2015/09/12 (S) Making It Usable

Leave a reply

In spite of all that we still have to get done on the bus we got up at 7:15 AM and went to our SLAARC breakfast.  We did not get to go last week because our grand-daughter (Madeline) was here and we won’t get to go next week because we will be at an RV rally.  We did not hang around like we sometimes do and left at 9 AM, but at least we got to go.

When I quit working on the toilet in the bus at 10 PM last night I had come to the conclusion that I had spent six hours trying to fix the wrong thing.  I assumed that the leak was due to a faulty O-ring or a misalignment of two pieces with the slip fit, presumably caused by the 9″ piece of Qest pipe with 1/2″ NPT lavatory fittings on each end.  After hours of effort and numerous attempts it occurred to me that the problem could be the threaded fitting in the first piece.  The fitting is unusual in that it is hollow and has an inside hex shape.  I got my SAE and metric Allen wrench sets but the largest wrenches, 3/8″ and 10mm, were too small and would not engage the fitting.

After dropping Linda at home I went in search of a 7/16″ and 1/2″ Allen wrenches.  I stopped at our bank for a little cash and then went to The Home Depot as they are next door to one another.  No luck there, but I did buy a 20″ flexible supply line with 1/2″ FIP threads.  I tried Lowe’s next but that was another strike out.  I tried O’Reilly’s auto parts store, the Tractor Supply store, and the Sears store across the street.  Nope, nada, nothing.  The guy at Sears suggested ACE hardware back in Howell so I headed that way but pulled into an Advance Auto Parts.  They had a set of Allen wrench (hex key) stubs, with 1/2″ drive sockets.  It included sizes smaller and larger than what I was looking for, in addition to the ones I was looking for, so I bought it.

Back home we installed the three large drawers in the rear of the bedroom.  I then spent several more hours working on the toilet while Linda changed out the handles on all of the cabinet doors.  She even figured out how to remove the handle on the built-in laundry hamper in the bathroom. As I have said here before, she is a clever girl.  I unscrewed the insert with a 7/16″ hex key, cleaned off the old thread compound, wrapped the threads with Teflon tape, and screwed it back in.  I mated the air/water sequence valve with the vacuum breaker and got them mounted to the support bracket, getting them aligned and snug in the process.

The last step was to attach the 20″ flexible supply line to the air/water sequence valve and water supply line.  I attached it to the air/water sequence valve first, looped it around, and attached it to the incoming water supply fitting.  Easy to say but tough to do.  There is a lot of stuff crammed into the back portion of this toilet and there is barely room to get one hand in there to work, never mind two.  To make matters worse (for me) the only hand I could get in there was my left one.  Being right-handed that made a difficult task even more so.

I turned on the water and checked for connection leaks.  I did not see any so I applied air pressure and initiated the flush cycle but it did not work.  Nothing, nada, zilch, no movement of the valve, drain flapper opening, and no flow of water.  The air-water sequence valve is mounted to a horizontal plate.  It installs from underneath and is held in place by a large nut that threads over the top.  I thought perhaps this nut was too tight and causing the valve to bind so I loosened it and the valve started working.  I flushed it several times looking for leaks and did not see any.  We made tiny adjustments to the location and decided to screw it down.  It was 3 PM.

I found the four screws that were originally used to mount the toilet to the floor.  They are very large and quite unusual.  They are 2.25″ long with coarse threads and hex heads with large Philips screwdriver slots.  The center of the heads, where the screwdriver slots cross, are drilled and tapped and there are four black caps with screws built into them that screw into them to conceal them and give the toilet a finished look.  I was concerned, however, about their length.  The underlayment and tile are somewhere between 5/16″ and 7/16″ thick, slightly thinner than the ceramic tile I removed, and the bus subfloor is (presumably) 3/4″ thick.  Anything that penetrates the tile by more than 1″ risks coming through the bottom side of the plywood and potentially screwing into something it should not.  I measured the base of the toilet and it was an honest one inch thick so I decided I would reuse the screws when we got to that point.

At this point we took about 45 minutes to clean up tools and put things away in the garage.  We then turned our attention to getting the built-in sofa installed.  I removed a piece of expanded metal mesh and cut a piece of aluminum sheet metal to cover a hole and used heavy duty double sided 3M tape to attach it to the HVAC duct.  While Linda cut pieces of felt to go under any pieces of the sofa that touched the floor I cut and attached foam weatherstripping to the back edges of the two plenum/support boxes and the return air duct/shelf.

We put the two plenum/support boxes in place against the end cabinets and HVAC duct but did not take the time to cut and screen openings into the duct.  We set the return air duct/shelf in place and put in the vertical front panel but the shelf held it out so I removed the weatherstripping from the back edge.  We also did not take the time to drill the 4″ holes at either end of the vertical panel for the round diffusers as there was no point doing this until the HVAC duct was modified.

We secured each of the plenum/support boxes to the wiring chase with a single angle bracket and to the front panel with a pair of brackets.  I drilled and countersunk a three foot length of 1/8″ aluminum angle and we installed it against the inside of the vertical panel and the top of the shelf.  The shelf is 45″ wide (side-to-side) and there is a 3″ high by 44″ long piece of the vertical panel missing at the floor and centered side-to-side.  The aluminum angle will transfer vertical loads on the central portion of the vertical panel to the shelf, which is 3/4″ plywood with full depth pieces along each edge and a slightly shorter central support piece.

We had been making a list throughout the day of parts that we needed.  When we got to a point with the sofa where we did not have the screws we needed we took a break.  We went to Qdoba in Howell for dinner, our first visit to this particular eatery since we moved to the Brighton/Hartland/Howell area, and both had vegan taco salads.  The salads were good enough although the taco shell bowels were not the best we have had.  The servers seemed a bit stingy with the various ingredients but in the end the salad was substantial and tasty.  It was also a convenient and efficient location being on an out lot of the Meijer’s supermarket property and right across the street from Lowe’s.

After dinner we went to Lowe’s and bought felt drawer/door bumper pads, screws, and two more angle brackets.  Back home we worked on the built-in sofa until 9 PM and called it quits for the night.  I spent two hours at my desk and finalized a featured bus article for Bus Conversion Magazine on Larry and Carol Hall’s GM4106.  I uploaded the article and photo files it to my Dropbox BCM folder, and then e-mailed the publisher, editor, layout person, and Larry to let them know it was there.

I try to finish these posts each night before I go to sleep or first thing the next morning.  If I fail to do that I quickly lose the sequence of events and details.  I tend to be up too late as a result, but if I fall behind by even one day it is very difficult to catch up while also trying to keep up.  As much as I have enjoyed the remodeling project I will be glad to not be so busy this winter and be able to write shorter posts about the interesting people, places, and things we experience.

 

2015/09/11 (F) Reassembling

I’m sure everyone who is old enough to remember September 11, 2001 remembers exactly where they were and what they were doing that morning.  Along with Pearl Harbor and the Invasion of Normandy 9/11 is certainly one of the most somber days of the year.

I was up late last night so I did not get up until 8 this morning.  I took a warm shower which was very refreshing.  (It was chilly overnight.)  I then fed the cats and made the coffee.  Linda got up and washed the blueberries, and we had granola for breakfast.  She worked at her desk while I researched expanded metal mesh.  It is readily available online in a wide variety of forms and basic stuff is apparently in stock at The Home Depot in Howell.

Linda needed to make deposits at two banks in Howell so we added The Home Depot to our errand run.  We picked up two small sheets of decorative metal screen and some other miscellaneous items.  By the time we got back to the car I had already decided that would probably not use the metal screens but we took them home anyway.

We finally got busy in the bus at noon.  Linda started putting the drawers back in and changing the handles in the cabinets.  It turned out that we needed #8-32×3/4 machine screws for at least some of the cabinet doors.  It also turned out that every drawer in the coach fit in a unique location.  In most cases it was obvious where a drawer went, but not all.  While she dealt with that I worked in the bathroom.

A portion of the OTR HVAC return air grill in the bathroom had been cut out, presumably by Royale Coach, but was not being used to pass plumbing or wiring.  It was yet another point of access for mice to get into the coach via the HVAC system (if that’s how they are getting in) but I wanted to seal it up while I had the chance (just in case it was).  I wanted to preserve the return air flow functionality of that area, however, buy covering it with expanded metal mesh.  I had salvaged some from the old furniture but had already used it as temporary screening on the HVAC duct by the living room sofa.  I had to uninstall a piece from there and cut it down to the right size.

It took way too much time to find my metal shears but I eventually did, in a tub with garden tools of all places.  I hate it when that happens.  It was an inauspicious and inefficient start to the day’s work.  Some of the inefficiency in this project can be directly attributed to the fact that we are still not fully moved in to this house after 2-1/2 years and do not have all of the tools and supplies unpacked and organized in a proper shop.  We spend too much time looking for things and even more time driving to the store to buy something we probably already own but cannot find.

We moved the toilet from the bedroom storage box to the bathroom and set it approximately in place.  We left the wood cover off the HVAC/wiring chase and then moved the toilet into position as far as possible.  Final positioning required the drain to be connected.  It was difficult to disconnect and even more difficult to reconnect.

The toilet outlet and the drain pipe get connected by a rubber sleeve with a stop in the middle.  A metal compression sleeve with two integral worm gear band clamps then goes around the rubber sleeve.  In order to get this assembled I left the compression sleeve off and got the rubber sleeve over both pieces.  We were the able to move the toilet back and make sure the two pipes were fully seated but it was a lot harder than this makes it sound and took a lot longer to do that it did to write these few words.

To get the compression sleeve on I had to unwind the worm screws until the bands popped out.  I spread it open and slipped it over the rubber sleeve.  I then put a zip tie around it to compress it and hold it in place while I bent the compression bands around and back into the worm gear.  Once I got them to “bite” I was able to use a 5/16ths socket on a very long extension to reach inside the back housing and tighten the bands.  Again, it was a lot harder to do than this description suggests and took quite a while to accomplish.  There is very little room to work inside the back of his toilet and the drain/clamps are at the very bottom near the floor with the only access being from above.

Next was hooking up the water and that was ordeal in its own right as I could not get the water line to line up with the plumbing in the toilet.  I eventually realized that the tile floor extended back over the bottom flange of the HVAC duct where the water supply line used to sit.  We heated the tile behind the toilet with a hair dryer and I then used sharp utility knife to trim it.  The nine inch piece of Qest pipe with nuts on both ends still did not want to line up with the supply pipe or toilet connection.  I eventually got it connected but it was a struggle.

Last, but not least, was the air.  The Microphor LF-210 is an air-flush toilet that uses 1/2 gallon of water per flush.  I started the bus to pressurize all of the air systems.  Once the auxiliary air tank was full I had Linda hold a rag over the open end of the air line and gave it five good blasts of air to blow out any debris that might have gotten in there.  I then shut off the air supply and connected the air tube to the flush actuator.  I turned the air supply back on, turned on the water pump, and opened the water valve.  Everything looked OK so I flushed the toilet.  Everything worked but we had a leak between two components where we had never had a leak before; at least not as far as I knew.  It was 4:30 PM and it was now obvious that we were not going to accomplish most of what we planned/needed to get done today.

The leak was between two of the fresh water components, the air/water sequence valve and the vacuum breaker.  The air/water sequence valve has a pipe with an O-ring that slides into a matching hole on the vacuum breaker and the leak was at that junction.  The vacuum breaker has a second hole, at a right angle to the first one, which slides over another stub with an O-ring that is screwed into the back of the toilet (inside) and feeds water to the bowl.  I ASSumed that the leak was due to the O-ring between the two parts having failed.  All told I spent another 6 hours on trying to fix the leak, including trips to various stores for O-rings, etc.

About 1/2 hour before I quit working for the night it occurred to me that the leak might not be the O-ring as the pipe with the O-ring is threaded into the air/water sequence valve.  It’s a pipe, so it’s hollow, but it threads into something and is smooth on the outside with nothing to put a wrench on.  Looking in the end, I saw that internally it was a hex socket.  I got my Allen wrench sets to see if I had the right size, but I didn’t.  My hex keys only go to 3/8″ and this was bigger than that.  It was 10 PM and I had spent 10 hours working on the installation and repair of the toilet without successfully completing the task.  Some days are like that and you have to take them in stride.  If you can’t (or won’t), converting (or reconverting) a bus is probably a bad choice of hobby.  For that matter so is owning a house and trying to maintain it yourself.  I guess life really is easier if you can just throw money at problems.

Given the progress of the work today we realized that we would have to delay our departure for Edwardsburg/Elkhart until at least Tuesday morning, and might not be able to leave at all if I could not get the toilet repaired without ordering parts.  We considered alternatives, including me taking the bus by myself to Coach Supply Direct and then bringing it home, skipping the GLCC rally in Elkhart.
