when shutting off fixtures throughout the house, a deep moaning horn sound emits through the pipes.....this occurs no matter which fixture is used and sometimes the noise occurs just out of the blue. Any suggestions?
COMMUNITY FORUM
Because it's caused by any and all taps, it must be in something common to the whole system. For lack of any better ideas, I suggest you go to the crawl space (or basement?) and have someone else make it fail. You might be able to find the problem by following the sound.
