2014/09/04 (R) More Organized

Darryll did not call last night so we knew he would not be here today. That gave us another day to work in the garage.  We moved things around, cleaned, sorted through stuff, decided what to re-store, and where, and what to add to various disposal collections.  We are pretty sure the old window A-C unit is going to our son’s house, so we loaded it in the Honda Element, which got it out of the garage.  Linda also loaded some old video and satellite TV electronics in the car to take to Recycle Livingston tomorrow.

We were making good progress and decided to stick with it and then have a slightly later lunch.  We removed all of the doors from some old kitchen cabinets, upper and lower, in the northwest corner of the garage.  We plan to eventually remove these cabinets, but not this year.  Without the doors we will be able to see what is stored in them, or at least that something is stored in them.  We moved a set of small parts bins and a bookcase which allowed us to reposition two work benches.  That, in turn, allowed us to move the radial arm saw and finally set the saw on the base and secure it.  It is now in a place where I could use it if needed, if it had power.  It requires a 240VAC/15A outlet.  I bought and installed a 30A double pole breaker in anticipation of this, so I will have to get a 15A breaker instead.

The weather forecast for today and tomorrow was for warm temperatures becoming hot with increasing humidity and chances for rain.  We closed the house up at lunch time and turned on the A-C.  We have hardly used it this summer, but have appreciated having in on those few sultry days.

We watched our current resident flock of wild turkeys—three adults and three young that have been in the area for a few weeks now—forage in our back yard while we ate lunch.  After lunch Linda decided to make banana bread as we had several bananas that did not get eaten fast enough.  She was researching dinner recipes when I went to my office to work on computer tasks.  Except for a dinner break, I worked late into the evening on the following:

  • Cleaning up (filing or deleting) e-mails
  • SLAARC Website user maintenance
  • Updating WordPress websites (ver 4.0 was just released)
  • Social media sites (RVillage, Facebook, Linked-In)
  • Editing daily blog posts
  • Off-loading digital photographs
  • Organizing photo storage

BTW:  Dinner was a new dish, a pineapple quinoa stir-fry with cashews, ginger, scallions, a little bit of hot peppers, and several spices/seasonings including fresh basil that Linda has been growing in the northwest corner of the kitchen where there is good light. It was excellent.

 

2014/07/18 (F) Tracing Circuits

When I talked to Steve from Village Landscape Development (VLD) yesterday he explained that they had not been out to work on our project because one of his employees had not shown up on Monday or Tuesday and late Tuesday informed him that he was done for the season for personal reasons.  Unfortunately for us, that employee was the crew chief for our project.  Steve said he spent Wednesday rearranging his crew assignments and assured me there would be people and materials at the house today.  When I left at 10 AM there was no sign of either, and no phone call letting us know when we might expect to see them.

I stopped at AAA Appliance to pick up the HVAC filters I ordered yesterday and then went to Lowe’s and bought the Square D Homeline electrical panel value pack.  It’s a 100 Amp main breaker panel with 20 slots and came with five 20 Amp single pole breakers.  I bought two ground bar kits, as well as a 20 Amp and 30 Amp 2-pole breaker (for 240 VAC devices).

As I was getting in the car to come home Linda called to see if I remembered to buy the weatherproof outlet covers for the outside outlets by the deck.  I had not, so I went back in to get them.  Apparently I forgot to buy some other electrical things I needed because I ended up with a non-contact voltage sensor, an outlet tester that works with GFCI outlets, and a system for determining which breaker supplies an outlet with having to turn breakers off and on until you find the right one.

When I finally got back to the house we installed one of the new filters behind the large return air grill in the living room.  We had to trim pieces of foam weather seal and pack it in to the small gap around the filter to force air to flow through the filter rather than around it.  We turned on the A-C to check the airflow and decided to check all of the registers.  There turned out to be return air ducts in all three bedrooms, which actually makes more sense than a single return in the living room.

The return air duct in the master bedroom had fiberglass insulation stuffed in it, presumably to cut down on winter heat loss, but there was no filter material.  Of the two supply ducts only the one farthest from the air-handler seemed to have airflow.  We removed the return air grill and cut a piece of the old living room filter material to fit and screwed the grill back on with the filter material behind it.

The return duct from the small bedroom had a thin piece of filter material behind the grill and adequate airflow from the supply duct.  We removed the return air grill, cleaned the filter material and re-attached the grill with the filter material behind it.  The middle bedroom had good air flow from the supply register but nothing to filter the air going into the return air duct.  We cut another piece of the old living room return air filter and installed it behind the return air grill.

I think we now have filter material on all of the cold air returns.  It strikes me as very odd that all of these air return ducts do not come together and then feed through a single filter.  We turned the A-C on and let it run while we had a quick lunch.  Except for the poor airflow to the one of the two supply registers in our bedroom, everything seemed to be working so we turned our collective attention to our next task.

The Coleman compressor/condenser unit was noticeably out of level.  Linda weeded around the base and trimmed back the rhododendron as the leaves of the closet ones were being sucked up against the heat transfer panels (radiator fins).  Once we had a little space around the base of the compressor we lifted the low side with a 3′ crowbar and slide a couple of bricks under that edge to hold it.  We had an old, unopened, bag of paver base so we used that to fill the large gap under the compressor base.  I scooped and placed it with a garden trowel and packed it with the end of a 1 x 2. We raised the unit a little and pulled the bricks out.  A minor tweak and we had it level.

We used the circuit tester to finish checking all of the outlets in the garage and the library and map what each circuit breaker supplied.  We discovered that the switch to the left of the sub-panel controlled an outside outlet mounted very high on the wall just under the soffit.  We have no idea why that outlet is installed where it is; perhaps it powered deicer cables or some other roof/gutter-related system at one time.  I was getting some very strange voltage measurements at the switch and at the outlet so I replaced both of them, but that did not change the readings.  I put a weatherproof cover plate on the outlet while I was at it.

Steve showed up mid-late afternoon with the excavator, his nephew Spencer, and a large role of plastic drain tile.  He used the excavator to move a couple of large boulders around back and then dig trenches for the drain tile.  He assured me there would be a crew here all day tomorrow, and he would be here to supervise them.

I needed to trim a stud in order to install the new electrical panel in my desired location but was unable to cut it with any of my existing tools.  What I needed was an oscillating cutter, so I headed back to Lowe’s and got one.  I was about to use it to trim out a section of a stud when I double checked a measurement and realized it was supporting the drywall that formed the northwest corner of the library.  Removing it was definitely not a good idea and that forced me to rethink the installation of the new panel box.  I do my best thinking when I’m asleep, so that was the end of my work for the day.

2014/07/17 (R) A-C Service

Allen from TOMTEK arrived a little before 9 AM to do the annual maintenance service on the air-conditioning system.  The A-C system looks to me like it was retrofitted to the house, but it’s hard to say how long ago.  The house has a hot water baseboard heating system so the air-handling portion of the A-C system (evaporator, blower, and flexible ducts) is all in the attic.  The air delivery registers are all in the ceiling of the main floor (it’s a ranch style house).  There is one air return grill in the living room with a 12″ flexible return duct a smaller register and duct from each of the three bedrooms.  The system does not supply conditioned air to the finished basement.

To service the air-handler Allen had to use a step ladder to gain access to the attic through an opening in the ceiling of a hall closet and then work his way through the trusses to the west end of the house.  He had to work by flashlight while lying down, having pushed insulation out of the way to make space.  It was a cool, but sunny, morning so at least the temperature in the attic was pleasant.  He cleaned and inspected the unit and checked it for refrigerant leaks and then had me turn it on.  He checked its operation while running and pronounced it good to go.  He also indicated that there was no evidence of an air filter anywhere in the attic.

The only other place there could be air filters was behind the return air grills.  The living room grill is up high on a wall in the northeast corner of the living room (cathedral ceilings).  I set up my 8′ step ladder so Allen could remove the grill and have a look.  Sure enough, there it was, only it wasn’t a typical furnace/A-C filter with pleated material surrounded by a frame and held in place by a wire fence.  Rather, it was just an oversized piece of loose fiber mesh filter material pressed into the square box that the return air duct attaches to inside the top of the other hall closet.  He removed it, took it outside, cleaned it, and re-installed it.  It was dirty but not completely clogged and Allen said the system was now drawing air better than before.  He then turned his attention to the outside compressor (condenser) unit.

The outside unit is a Coleman, and that is about all we know.  The information plate was so badly faded that Allen was unable to get any of the information he needed from it.  He cleaned and inspected the unit, checked it for refrigerant leaks, and then hooked up his special test fixture.  He said it was working properly and did not need refrigerant, which was a good thing because refrigerant is very expensive and is not included as part of the pre-paid service call.

After Allen was done and had left I climbed back up and measured the return air box.  It was 16″ x 16″.  We checked Lowe’s and Home Depot online and could order one that size but it would not get here until next week.  With company coming Sunday I wanted to complete this project and put the furniture back in place and not have to move it again.  I drove into Howell to check the local stores but they did not stock that size filter.  The guy at Lowe’s suggested I try AAA Appliance (AAA Service Network) just down the street.  They did not have that size in stock either, but they could order one and have it by Monday.  They were cheap enough that I ordered four of the 2″ thick ones.  (I got a call at 5 PM that they had arrived and were available for pickup.). While I was out I also shopped for a new electrical panel for the garage.  I checked Home Depot, Lowe’s, City Electric, and Standard Electric Supply.  I did not buy anything, but that’s a story for another post.

While I was out Linda moved a few more items into the storage container and dealt with much of the stuff we had moved into the library yesterday.  When I got back we worked together to move even more stuff into the container.  That, in turn, freed up space in part of the garage that allowed us to move three of the large stationery shop tools out of the area where Darryll and I will be working.  The whole impetus for the storage container is to clear out the east half of the garage so Darryll can install the garage heater and the new HVAC unit for the library.  As long as we had to make space for him to work, it was an opportunity to further empty out the garage, repair some things, and rearrange where/how we have things stored.  It seems sometimes like a never-ending process as there isn’t really a place for everything so it isn’t possible for everything to be in its place.

In the center area of the back (north) wall the previous owners had removed the drywall and installed Wonderboard to act as a heat shield for a wood burning stove.  The husband restored old cars and used the garage as a shop.  We saw the stove when we looked at the house in January 2013.  Wonderboard is normally used as the substrate for laying tile but contains concrete, so it also works as an insulator against heat and doesn’t burn.  I wanted to drywall this area and decided to remove the Wonderboard.

I removed the Wonderboard and discovered two things:  There was another layer of Wonderboard underneath and there was visible evidence of a fire.  When I removed the second layer of Wonderboard the extent of the damage was fully revealed.  One 2×4 stud was burned almost completely through for about 12″ and the paper facing on the insulation on either side of it was charred.  An electrical wire also ran through that wall and the insulation was discolored.  Such is the nature of remodeling projects; you never know what you are going to find.

I spent a little time after dinner trying to figure out what each of the circuit breakers in the garage sub-panel controlled.  There are 12 breakers occupying 14 of the 16 positions.  I figured out that four of them controlled about 90% of the outlets in the garage.  It dawned on me later as I was discussing this with Linda that the other breakers might supply power to the library.  I will have to verify that tomorrow.

 

2014/07/14 (M) Education

Linda was up at 6 AM and was out the door and on her way to Twelve Mile, Indiana at 6:30 AM.  She decided last night not to have breakfast at home in favor of getting on the road.  I slept in and got up at 7:30 AM.  Lind’s homemade granola made for an easy, tasty breakfast.

Two landscapers showed up a little before 9:00 AM as I was getting ready to leave to run some errands and said Steve was on his way, so I stuck around until he got there.  We looked at a few things together and then I left.

On the way home from running my errands I got a call from TOMTEK reminding me that we have an annual service contract with them for the main house furnace (hot-water base-board heat) and air-conditioner.  I agreed to have them come on Thursday to service the A-C.  Perhaps while they are here they can figure out why it makes a noise that sounds like the thump, thump, thump of a helicopter blade.

About a mile from the house I spotted a small Painted Turtle trying to cross Hacker Rd.  A truck going the other way spotted it at the same time.  We both turned around and came back.  I got there first and put it on the front passenger floor mat after assuring the other driver that I was going to take it to our property and release it near the (neighbor’s) pond.  Turtles have very little chance of successfully crossing a road most places, including around here.

The two landscapers worked into the afternoon.  They could only go so far before needing Steve to inspect and approve their work.  He did not make it back today and I think they quit working around 3 PM.

Education is what I did professionally for the last 21 years before I retired, and I am still doing it to some small extent.  Back in the late winter I agreed to serve on a newly reconstituted FMCA national education committee.  There are 6 – 10 people on the committee, depending on how you count, and except for a couple of staff at FMCA headquarters in Cincinnati, Ohio we are spread out all over the U. S.  Our meetings are, therefore, conducted by telephone conference with ideas and information shared via e-mail in-between.  I also set up a folder in our personal Dropbox as a place to put documents so the committee can retrieve them.

We had our third meeting today from 4:00 to 5:30 PM EDT.  I spent the rest of the evening creating an outline of a possible RV curriculum and dealing with e-mail related to our meeting.  Linda got home at 8:00 PM and we had leftovers for dinner, after which I returned to my work and she headed to bed.

I have one, maybe two, days to concentrate on desk tasks.  Once the Pack-Rat storage container arrives on Wednesday I will be tied up with house-related chores through the 19th and then company through the 23rd.  I expect delivery of some HVAC equipment and materials during that window.  With any luck Darryll will be here starting on the 24th and I will be tied up working with him through the end of the month.  I’m hopeful, if not optimistic, that the landscapers will also be done with their two projects by the end of the month.

 

2014/04/07 (M) Big Wheels Keep On Turning

The boots may have been made for walking, but the wheels were made for turning and it does not make much sense (to us) to own a motorhome and not use the motor to move the home around at least occasionally.  Checkout time at Williston Crossings RV Resort is nominally 11 AM.  We were planning to leave by then, but a call to Suncoast Designers at 9 AM caused us to push our departure time back.  They suggested we not arrive until about 4 PM to make sure we had a place to park with hookups.  That put our departure time target at 2 PM.  We walked up to the office to make sure this would be OK.  It was; we have been here a long time and been good residents, and no one was scheduled to go in to “our” site today.

Given some extra time we had not planned on, we went for one last, long walk around the RV resort.  How different it looked and felt.  The resort is turning over from long-term winter/seasonal use to short-term summer/vacation use and there were many empty sites.  Eighty-nine rigs left yesterday.  Many were Carriage 5th wheels that were part of the 70 rig Carriage Travel Club rally that was here all last week.  But some were winter seasonal residents who have been dribbling out since April 1st and will continue to do so into May.  We were not the only rig pulling out today.  Our other neighbor, Sharon, is leaving this coming Sunday.  A few rigs were pulling in, of course, but the departures currently exceed the arrivals on any given day.

When we returned from our walk I mixed up a batch of the concoction we use in the waste holding tanks (48 oz PineSol, 48 oz water, 1cup Calgon).  I dumped the black-water tank and back-flushed it, followed by dumping the grey-water waste tank.  I ran additional water through the drain hose and then disconnected the hoses and fittings and stowed them for travel.  I reconnected the water softener and filled the fresh-water tank.  Once that was done Linda helped me disconnect, clean, and stow the fresh water hoses and the water softener.

We tend to forego coffee and breakfast on travel days, but had a little of both this morning as we were not leaving right away.  Because of the delay in our departure we did not have lunch.  To pass the time I continued with travel preparations.  The last time I had the coach batteries connected I noticed that the Pressure Pro TPMS (tire pressure monitoring system) was not reading one of the sensors (PS outside drive tire).  We have a repeater for this system that I plan to install in the rear of the coach someday, but for now it gets attached to the rear view mirror of the car.  I took care of that task and then decided to move the car up onto the patio next to passenger side of the coach.  I left the ignition on to power the repeater and connected the coach batteries to power the TPMS receiver.  After a few minutes all of the tire sensors were active and the tire pressures were OK for travel.  I disconnected the coach batteries and put the car back in front of the coach.

At 1:30 PM we started our final travel preparations, clearing off the counters and moving stuff from the cockpit to the sofa, the bed, and the bedroom floor.  At 1:45 PM I shut off the 240/120 VAC electrical power to the coach, disconnected the shoreline, and stowed it in the slide-out tray over the DS drive tires.  I installed the screw-in cover for the utility port hole in the bay floor, and closed/locked the bay.  I then checked the Magnum 4024 to make sure it had switched to inverter mode, which it had.

Once the shore power is cut we seem to develop an increased sense of urgency about leaving.  I think this is due, in part, to the fact that I do not have the ZENA power generator operational yet, so our house batteries do not get charged while we are driving.  That’s OK, up to a point; the battery bank was designed to be large enough to run the inverter and power reasonable loads for a reasonable length of time.  But the sooner we leave, the sooner we arrive, and the sooner we arrive, the sooner we can plug back in to shore power.  We have an auxiliary power plant, of course, so we always have the option of using that if needed.  The other reason we are probably anxious to leave is more psychological.  Once we are completely disconnected (physically) we are become disconnected mentally, although not necessarily emotionally.  We are no longer “tethered” to that spot, and that means it is time to go.

I connected the chassis batteries, fired up the engine, and set the level low system to the driving position.  While Linda moved the car to street I drained the auxiliary air tank using the nice dry air from the main engine air compressor.  With John’s assistance we got the coach out of the site and lined up on the street.  Linda pulled the car up behind the coach and we went through our procedure for hooking it up to the tow bar.  We did our standard light check and found that the turn signals on the car were not working.  A quick check of the connectors on both ends of the cable revealed a socket on the car end of the cable that was corroded.  I used the awl on John’s Swiss Army Knife to clean it up.  A recheck of the lights indicated that everything was working.  After a final “goodbye” with John and Ali we were on our way.

Our departure delay meant we would be traveling SSW into the sun at the hottest part of the day.  The air temperature was 85 degrees F when we left, and the engine ran slightly hotter than usual, indicating just above 195 degrees F on the coolant temperature gauge, so I decided not to run the coach air conditioning.  The drive to Hudson was warm, but not unbearable.  A cold front was approaching the gulf coast of Florida so we had increasing cloud cover as we progressed south and west towards the coast, which helped keep the cockpit from getting too warm.

We had a nice run from Williston to Hudson.  We headed south out of Williston on US-41/US-27/FL-121.  US-27/FL-121 split off to the west a mile south of town, made a sweeping turn to the left and then followed a nice straight line SW for 17 miles to its southern terminus at US-19.  This stretch of FL-121 is straight but hilly.  With the cruise control set the engine is very sensitive to hills.  I always know we are on a grade, however slight, by the reaction of the turbo boost gauge and the pyrometers.

Most of the rest of trip was on US-19 except for the last three miles.  Traffic was light until we got to Crystal River, which had slower speed limits, lots of stop lights, and lots of vehicles on the road.  It opened up a bit after Homosassa Springs, but got congested as we approached Weeki Wachee where FL-50 ends at US-19.  From Weeki Wachee to just north of Hudson traffic remained slow and congested with increasingly dense commercial use on both sides of the road and stop lights every mile.  Just north of Hudson we turned east onto Little Road, which immediately swung south, and followed it for about two miles to New York Avenue, where we turned west and went another mile to Labor Place, the location of Suncoast Designers.

The coach ran fine, although the Check Engine Light came on almost immediately and was on more than it was off for the whole trip.  That did not surprise me as we had not done any work over the last couple of months to fix the fuel temperature sensor voltage problem that is apparently setting a fault code in the DDEC II.  I had hoped that the repairs we made in the dashboard wiring harness would fix the speedometer/odometer problem, but they did not; the gauge sat on zero for the whole trip.  The left pyrometer (exhaust gas temperature) gauge, however, was much more responsive and tracked the right pyrometer gauge much more closely than it ever had before.  It appears that the wires we repaired were for this gauge rather than the speedo/odo.

Once we pulled in to Suncoast Designers we pulled to the side of the road, so as not to block traffic, and unhooked the car.  While Linda parked the car I found the office and checked on parking arrangements.  Suncoast Designers has at least a dozen RV sites with water and 50 A electric hookups.  The only one open was a somewhat tight spot between two other large Class A motorhomes that required me to back in.  The maneuver was made more difficult by the fact that the road in front of the sites had a curb on the far side and was not wide enough to allow me to swing the front end without scrubbing the front tires.  I repositioned the coach so that I was turning in from the driver’s side, but Linda and I could not figure out how to get the coach into the site.  The guy next to us on the driver’s side offered to help.  A former truck driver, he knew exactly what to have me do.  Unlike some RVers, our pride is not injured by not knowing how to do something, and we gladly accepted his help.

I pulled past the site close to the front of his rig and then turned out to the passenger side, putting the coach at an angle to the open site.  He had me back part way into the front of the site at that angle and then turn the steer tires full left to start to bring the coach around.  He had me stop and then turn the steer tires full right and pull forward.  Steer tires full left again and back up some more, then full right and pull forward. We repeated this one more time and finally had the coach lined up straight and centered between the coaches on either side without having hit either one!  Linda was keeping an eye on the back of the coach the whole time (to make sure I did not hit anything) and guided me into our final position.  We then leveled the coach and shut the engine down.

The outside air temperature was only in the upper 70’s, but it was 90 degrees F in the coach and the outside humidity was high.  In spite of having nine windows that open, the three ceiling vent fans are not very effective at cooling down the interior under such circumstances.  In theory we can run all three air conditioners on a “50 A” shore service, but we have tripped breakers before when doing that.  (The issue is that circuit breakers are commonly designed to only carry 80% of their rated current on a continuous basis, so two of our A/C units plus a little bit of miscellaneous load can exceed 40 A on one of the legs.)  Besides, as soon as I plugged in the Magnum 4024 was going to switch to charger mode and start recharging the house batteries.

I got the shore power connected and checked the Magnum 4024.  It went into bulk charging mode and started charging the house batteries at 86 Amps. Since it is a 24 VDC charger, it was drawing ~1/5 that much AC current, or ~17 A, the equivalent of one of our air conditioners.  The front (living room) and center (kitchen) A/C’s are on separate legs of the 240/120 VAC power supply, so we can run them at the same time.  The bedroom A/C is on the same leg as the front A/C and the Magnum is on the other leg.  We ran the front and center A/C’s along with Magnum and let the bedroom stay warm for the time being.

Suncoast Designers provides free WiFi for customers camped at their facility, but the signal we thought was theirs indicated it was “filtered” and we had not obtained the login information from the office before it closed.  We used our Verizon MiFi instead and had a good, strong signal.  I had a chance to ask our neighbor (helpful truck driver guy) later, and he said the open signal was the one they were using.  Although it was a weak (one bar) “g” signal, our WiFi Ranger latched on to it without difficulty.

Linda needed a few grocery items and located a Publix grocery store on Little Road less than three miles from Suncoast Designer’s.  As evening settled in we switched off the front A/C and turned on the bedroom unit.  Linda reheated some of the leftover Sloppy Joe’s from the pot luck dinner the night before, and we had that on the skinny buns we have started using, along with a simple spinach salad and a few Fritos corn chips.

After dinner Linda sent e-mails to several of our new friends from WCRVR while I checked in to RVillage and took care of a few e-mails of my own.  The overnight temperature was forecast to only drop into the upper 60’s with high humidity, and with rain starting before sunrise, so we decided to leave the rig closed up and the kitchen and bedroom A/C’s on all night.  We rarely do this because of the noise and because we prefer fresh air, except when it is too warm and/or too humid.  Considering that we had traveled less than 100 miles and been on the road just under two hours today, we both felt like it had been a very long day.  As much as we enjoyed the social life at WCRVR, it was nice to not have anything to do but go to bed and get some rest.

 

2013_09_06 (Fri) House Systems

I have often commented here about the “house” systems in our converted coach; the water (fresh and sewage) and electrical (lights, appliances) systems and their components that make a large motorized vehicle behave like a stationary house.  Those components include things that are found in any stationary dwelling (water and sewage pipes, plumbing fixtures, electrical wires, circuit breakers, switches, light fixtures, appliances, etc.), things that are found in some stationary dwellings (sewage tanks, macerator pumps, well pumps, fresh water pressure tanks, reverse osmosis systems, power generators and transfer switches), and things that are not commonly found in stationary homes (yet) (various gauges, batteries, inverters & chargers, power protection devices, solar panels, and even wind turbines.)  RVs do not have geothermal or low-head hydro systems.

Today, however, was about actual house systems, that is to say, systems for our actual (stationary) house.  We have had a “rotten egg” smell in our domestic fresh water system since we bought the house and finally called Adams Well Drilling and Water Treatment, a local Howell-based company, to come out and take a look at our current equipment.  Brian arrived as scheduled at 9 AM and we walked him through the complete fresh water system.  He took some water samples directly from the well (before any filtering, softening, or other treatment).  The good news was that our dissolved iron was at 1.2 ppm (mg/L), which is a treatable level, but above the 0.3 ppm at which iron starts to become a problem in the water.  The less good news came from two directions: 1) that our Water Boss water softener wasn’t doing a very good job and 2) we appeared to have iron bacteria, which a regular water softener doesn’t treat very well (or at all) even with the special “iron out” salt.

We discussed a range of options but Brian’s recommendation, which we accepted, was a new water softener and a “carbon unit”.  The carbon unit is self cleaning using special chlorine crystals, and is very effective in dealing with iron bacteria.  We will also have new sediment and taste filter housing installed as part of the installation.  There may be other issues with the water system in this house, which was built in 1977, but the water treatment equipment was probably due to be replaced regardless of what else we do.  The following website from the Illinois Department of Public Health gives a nice synopsis of iron in drinking water:   http://www.idph.state.il.us/envhealth/factsheets/ironFS.htm .

The other fresh water issue we have, based on the testing that was done as part of the purchase inspection, is Arsenic.  The level that came back from the lab was 34 ppb (ug/L).  The old “safe” level was 50 ppb, but the current “safe” level is 10 ppb.  Zero ppb would be ideal, of course, but is not achievable at a reasonable cost. To further complicate matters, there are two kinds of Arsenic found in well water: Arsenic 5 and Arsenic 3.  The prior water testing did not test for these separately, but the sample Brian took today is going to a private lab that can/will test for each separately.  We were told previously that Arsenic 5 is the more typical and is mostly removed by Reverse Osmosis (RO) but that Arsenic 3 is not removed by RO.  The house has a Culligan RO system installed that supplies water to the refrigerator and a special faucet in the kitchen sink.  It was in the house when we bought it and we decided to continue renting it until we could determine our true needs and consider our options.  Not knowing if we had Arsenic 3 in our water, we purchased a special Arsenic 3 filter from Culligan which installs in the manifold after the RO membrane.  We made a call to Culligan to check on our contract and got a call back from our rep (Jeff) who has been a good guy to work with.  Long term it makes no sense to rent the unit, so we are exploring purchasing it or removing it and having Adams install a similar system.

While Brian was doing his thing, Darryl showed up from DMC HVAC.  Darryl did the HVAC installation for our office/library/garage addition/renovation at the old house and did a great job.  When it comes to contractors I like to use local people when I can but I also like to stick with people we have worked with before.  Darryl is not local to our new place, but he is a known quantity whose work we respect.  Although we have a loop from the hydronic hot water heating system in the Florida room/library, it has some issues.

The major issue is that the supply and return lines run through the ceiling and into the wall which adjoins the garage.  We think this house originally had a detached garage with a concrete patio between the garage and the end of the house.  Sometime later a roof was added connecting the house and the garage and the two open sides were closed in with 16 feet of doorwall and fixed glass panels.  The only practical way to extend the heating systems was to run the pipes overhead.

The other issue is that this space does not have air-conditioning.  (There is a small window mount unit in the garage wall.  Yup, it exhausts heat into the garage.)  We have space in a corner of the garage by this room to install a small forced-air furnace/air-conditioner and get the air to/from the room easily along the garage ceiling.  We would also like a ceiling mounted forced-air furnace in the garage so we can store paints and other things that we want to be able to keep above freezing, or bump the temperature up a bit and have a comfortable place to work.  Darryl installed one of these at our old house, and it was a very nice feature.

In anticipation of this work, we had a second propane tank installed next to the garage when the whole house backup generator was installed back in May.  I told AmeriGas at the time what we planned to do so they did a temporary installation of the tank and ran a line directly to the generator.  One of the thinks Darryl will need to do is mount a permanent pressure regulator on the side of the garage and then run pipe to get the propane over to the two new furnaces.

As Darryl was finishing up, Tom and Tom showed up from TOMTEK HVAC.  TOMTEK is a Howell-based company that we decided to have service our hydronic heating system.  It’s an old Weil-McLain Gold unit with some corroded parts.  It was also filled with water.  When we looked at the house originally the heating loop to the Florida room was shut off.  It turned out that something had failed while the owners were away during the winter and that loop had frozen and ruptured.  They repaired it prior to closing, but I never did understand why the system didn’t have an appropriate anti-freeze in it instead of water.  As of today, it does.

One of the nice things about hydronic heat is that it is easily zoned.  Our system has four zones, each with its own thermostat.  One of those thermostats also controls the air-conditioning for the main floor of the house.  That may seem odd, but it is a consequence of the A/C unit probably being added sometime after the house was built.  As a result, the air handler is in the attic and all of the air ducting is too.  It’s a single system controlled from a single point, and is completely separate from the hydronic heating system except for this one shared thermostat.  It was the failure of this particular thermostat that prompted us to go ahead and contact TOMTEK and have them out to service the system and install four new thermostats.  The one that controls the living/dining rooms and kitchen, as well as the air-conditioning, is a Wi-Fi enabled device that will allow us to monitor the temperature in the hallway, which is the most central point in the house, and control the main heating loop and the air-conditioner remotely if we so desire.  Pretty cool; literally.  The “boiler” needed some additional service for which TOMTEK had to order parts, so they will be back another day to finish up the maintenance on the unit.

Overlapping contractors made for a somewhat intense day.  Fortunately there were two of us available to interact with them, and they all got the attention they needed from us, when they needed it.  As soon as Brian was done I called Adams Well Drilling and Water Treatment and scheduled him to come back on the 11th to install the new water treatment equipment.
