In response to Re: New home....concrete floor or crawl for plumbing repair ease ???
: In Arizona, I don't think they would even consider a crawl space no matter how much you wanted to spend. The water piping is all under the slab and there are relatively few problems. The majority of the underfloor leaks are caused by the plumber kinking the tubing when he comes up in the wall and the hot water flexes the kink. Over time the constant hot/cold cycles cause the kink to develop a crack. If this were to occur, you homeowner's insurance normally covers the cost of the repairs, minus your deductible and the cost of actually repairing the pipe.If the water piping, particularly the hot water, is enclosed in a foam insulation, which you should do anyway for energy savings, you shold have no problems.

I had a leak under the slab. It was caused by the chemicals in the soil attacking the copper pipe. Have your builder wrap or insulate the pipe so it is not in direct conact with soil or concrete. Even so, my insurance took care of it and it really was not a big deal to have repaired.
