Just read all 83 pages of this thread (yeah, I need a life). Fascinating, enlightening, horrifying. And worth the time.
1) I learned that I'm the guy who fixes everything (heck, I built this house 15 years ago) and Dear Bride (tm) will really need an "operators manual" for it if something happens to me. Not worried about "something" but it is better to be prepared.
2) I learned that I really need to drain the water heater and change the anode. I've known that but somehow never gotten around to it. I even have the replacement anode.
3) I learned that we made the right decision to build with light gauge steel and face with block (split face decorative, it doesn't look like a bomb shelter). There is NO WOOD in this house except for the furniture. My building philosophy is this - wood is for hippies, steel is forever. Termites do not eat galvanized steel (even the roof trusses are steel, as is the underlayment and the roof itself), steel doesn't burn, doesn't rot, and if properly galvanized, will long outlast the two of us. I used to be a slumlord and I know lots of ways NOT to build houses.
4) I learned that I really need to redo the well pump plumbing and the paving slab (14" from Home Depot) the pump is on. The slab is settling and stressing the PVC pipe - one of the unions broke already, but the whole thing is poorly thought out even though it was installed by a professional well driller. Time for new PVC, new shutoff ball valves, an in-line centrifugal sand filter (have it), and a better filler cap to re-prime the well if the system is opened. Right now, it gets filled by unscrewing the pressure valve, inserting a funnel, and pouring. It needs a bigger opening.
I'm also going to add an anti-vibration pad or rubber mounts (like car engine mounts) under the pump. I already have a thermostatically controlled heat tape on the pump body. Fortunately it very seldom gets cold enough for that to kick on, and I do know that over the past decade it has become slightly warmer in the winter here (USDA plan zone 9B is now south of us, a decade ago it was north of us).
5) I learned that I'm a pretty passable electrician. I wired this house and a 50 by 90 workshop (110 and 220, lights and outlets everywhere), and there are NO exposed wires and ABSOLUTELY NO wire nuts anywhere. GFCIs and whole house surge blockers as needed, all the wiring in the workshop is in conduit, zoned lighting because if I turned everything on at once, you could see the building from space.
6) I have to pay some attention to the bathroom. The sink trap is connected with one of those accordion pipes because the PVC flat refuses to line up properly, and from what I read here, those things are an affront to civilization, which I did not know when I bought it. The toilet needs a rebuild (no big deal) and I have to change the shutoff valve to it - the handle and stem disintegrated. Finally, the grout in the shower floor is crumbling and it needs to be re-grouted.
All in all, I think I have a couple of full days work here (which I'll do a little at a time) and we'll be all set for the next 15 years (by which time we will have bought another water heater and water softener).
Comments are solicited by anyone here who is more experienced that I am (which means everybody), I like to fix things ONE TIME and be done with them, and I do appreciate and even follow advice!
Thank you and best regards,
Mike/Florida
