A year old house is starting to have a noise problem when water, hot or
cold, is turned off in all locations. Coming from the pipes behind the
walls, a low frequency groan lasting several seconds .
This is a new phenomenon never noticed during the first year.
I am wondering if the outside water pressure regulator is going bad. I have
no other ideas.
Any comments help appreciated,

Groaning, moaning, fog-horn type resonances are
almost always caused by a failing toilet ballcock.

Have someone create the groan while you go around
and either shut off each toilet supply in turn or
hold the tank float up. That should tell you
which one to replace.

Thank you for the idea. Will try.
Best,

I've had that happen a couple times. Try bending the arm on the float
downward a little and see if that takes care of the problem....

You don't happen to live in or near Amityville, do you?
