#2 is probably the most important. If the pipes are leaking, then a hot spot is usually where the leak is.
: I need some advice on what I think is a leak in the hot water side of my plumbing.
: The house has a concrete slab floor.
: The symptoms are as follows:
: 1) Cold water starts out cold, gets hot, then cold again.
: 2) Noticed "hot spots" on kitchen and bathroom floor.
: 3) New Rheem 12-yr guarantee water heater makes noises when all hot water faucets are shut off in house.
: 4) Water heater noises cease when water supply to hot water heater is shut off.
: Any words of advice for further diagnosing and localizing the problem? Is there any fix short of getting a jack-
: hammer and opening up the floor? Note that it is a 2-story house so running a bypass through the attic is NOT an option.
: Thanks for any help.
