2015/05/24 (N) Nuts to That

Leave a reply

We had our usual coffee and breakfast granola but made a more leisurely morning of it than normal.  We finally got dressed around 11 AM and headed to the Howell Farmers Market at 11:20 where we bought another bar of soap from Marjorie.  I got to pick this time and chose the ginger-grapefruit.  We bought the Eucalyptus soap two weeks ago and Marjorie suggested letting them air dry for two weeks before using them.  We will see how long the Eucalyptus bar lasts once we start using it and that will tell us how often we need to purchase from her to stay ahead of our usage, allowing for drying time.

We stopped at Lowe’s to return the “white” toilet seat and buy a “biscuit” colored one.  We looked at pipe wrenches but did not buy one.  I did by a 14 TPI, 6″ long blade for my Sawz-All that said it would cut metal up to 1/2″ thick.  I still hoped to get the nut off of the trailer ball on the lawn tractor without having to cut the threaded stud, but the blade was my backup plan.

We had a brief confab regarding the motorcoach refrigerator alcove and cabinet.  I found my small plumber’s toolbox and it had several pipe wrenches inside.  I took the largest one and checked to see if/how it would fit the trailer ball on the lawn tractor.  It opened more than wide enough and looked like it would snug down tight around the throat of the ball (between the ball and the hex flange base).  Linda kept the pipe wrench from slipping out of position on the ball while I used the torque wrench with the 3/4″ drive, 1-1/8″ socket to remove the nut.  It was still a bit of work but we got the ball off without cutting, cracking, or heating.  I then backed the lawn tractor up to the utility trailer and Linda connected the trailer yoke to the tractor tow plate.

Next we tackled the hall bathroom toilet seat replacement.  Once again we encountered nuts that would not come off.  This time the nuts were a hard plastic but the bolts were rusted and the nuts would not turn.  I eventually cut through the two plastic nuts with a utility knife and pried them apart allowing us to remove the old retaining bolts.  We installed the new seat/lid which came with its own special bolt and elongated plastic nut.  The nuts had special tips designed for 1/2″ sockets and engineered to break off when tightened to just the right point.  We had both nuts torqued down and broken off but the seat was slightly crooked so I had to loosen then, reposition the seat, and re-tighten them by feel.  What should have been a simple, short job ended up being a long and difficult one, in part because there was not a lot of room on the sides of the toilet bowl to get under here and work.  As we were cleaning up Linda noticed that the toilet tank was leaning slightly to the right relative to the base/bowl and thought we should adjust it.

I was already aware of the leaning tank, and the fact that it was not as tight as it should be.  The tank is held to the bowl by two bolts that go through the bottom of the tank and are sealed by gaskets under the heads.  I tried tightening the wing nut on the left bolt.  Even though it was rusty I was able to turn it, but the tank immediately started leaking from the bolt hole in the bottom.  We shut off the water and flushed the toilet to get most of the water out of the tank.  Linda held the left bolt head with a long flat blade screwdriver while I turned the wing nut on the underside of the bowl, first by hand and then with pliers.  I was careful not to over torque it and the tank was still a bit wobbly, but it was straighter and it did not leak when we refilled it.  We will keep an eye on it.  A leaky tank will result in water continuously running onto the floor and causing major damage of not detected quickly and stopped.

Linda cleaned up the bathroom while I put the tools away.  We then changed the primary whole house water filter.  The filter we use is the same 10″ length as a standard potable filter element but is about 5″ in diameter and has two micron ratings.  It’s a spun polypropylene media that is 50 microns at the large outer surface and 5 microns at the small inner surface.  In principle it filters better and longer than a single micron rating element by filtering out larger particles first and thus not clogging up the 5 micron material with large particles.  The same thing would be accomplished, of course, with two filters in series, or three, or four, each with progressively smaller micron ratings.

The Post-It note by the filter said we had last changed it on 11 November 2013.  If that was true it was way overdue to be replaced.  The element was completely black from outside to in so it had been in there longer than the fall of 2014 for sure.  We are starting to get some slime in the toilet tanks again and the water seems to have a slight black tinge, but that may have been due to the filter element needing to be changed.  I may need to have Adams Water Treatment come out again to discuss installing an iron filtration system.  Our drinking/cooking water still goes through a reverse osmosis system, so it is very pure.

Having accomplished several rather physical tasks I decide to sit in the living room and work on my blog posts for the last few days.  Linda made hot tea for us to enjoy while iPading, after which she reheated the leftover risotto and asparagus from last night’s dinner and we finished the open bottle of 2013 Egri Merlot.  After dinner I finally settled in to work on computer-based tasks.  I had a long list of things to do but did not get to most them.  I did manage to off-load recent photos of the bus interior from my camera to my computer, select a few to use in blog posts, and processed them.  I edited a few more blog posts but did not get them uploaded to our website.  I then dealt with e-mails and went to bed.

 

2013_09_11 (Wed) Fresh Water Systems

Leave a reply

On Wednesday we had a new water treatment system installed by Brian and Matt from Adams Well Drilling & Water Treatment.  When Brian was out the week before he determined that our old Water Boss water softener was not working very well.  This came as no surprise to us based on the house purchase inspection, but we had hoped it might last a bit longer than it did.  Alas, he also determined (confirmed) that we had sulphur-reducing bacteria and probably iron bacteria as well.  The water has always had a slight rotten egg smell (hydrogen sulfide) but had gotten worse recently.  The inside of the toilet tanks had also become a nursery of sorts (iron bacteria), so something clearly needed to be done.  They removed the old Water Boss water softener along with the old sediment pre-filter and carbon post-filter.  We also had them remove a Culligan Reverse Osmosis (RO) system.  The only thing that remained from the old system, other than pipes and tubing, was the Well-X-Trol storage/surge tank (and the well pump, of course).

With the old stuff out of the way, they first installed a new large capacity, dual porosity sediment pre-filter.  The replaceable filter element is 50 microns on the outer portion and 5 microns on the inner portion.  Although 5 microns is relatively small, the element has enough surface area to pass many gallons of water per minute.  They reconfigured some of the pipes and fittings and then installed a Water Right water softener with a large brine tank, and a Water Right carbon filtration unit with a chlorine pellet tank for the unit’s self cleansing feature.  The softener will treat about 800 gallons of water before needing to regenerate the media and has a controller that tracks the usage.  (By comparison our Water Boss regenerated every 300 gallons.)  It will also learn over time what our water usage pattern is and adjust the regen cycle accordingly.  For this reason it would be in our best interest to standardize when we do things like laundry and running the dishwasher.  To date, however, our life in retirement has lacked that degree of routine.

Their last task was to install an RO system to replace the Culligan system they took out.  The new system has a pressure boost pump on the input, a pre-filter, RO membrane, post-filter, large storage tank, delivery pump, and finally an Arsenic 3 filter.  They replaced the Culligan faucet at the main kitchen sink.  They also ran a line to the bar sink in the basement where they removed the old Insta-Hot and installed an RO faucet.  Since Adams also drills and services wells (and probably installed the one in our house many years ago) we now have one local vendor responsible for our entire fresh water system, with the exception of the hot water heater, from well to faucet.  The water heater is part of the hydronic heating system and is serviced by TOMTEK HVAC.

Wednesday was also our Door-To-Door Organics delivery.  Linda has a standing order for the “bitty fruit” as it is an appropriate size for us and the fruit is usually quite good.  She has found that she does better buying vegetables on a more frequent, as needed basis, and gets what she can from the Howell Farmers Market on Sunday mornings if we are around.

 

2013_09_06 (Fri) House Systems

Leave a reply

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.
