I am having difficulty with what I believe is air in my pipes. I hear
a very long and loud groan often, and from almost any tap. It is

while we do the laundry. Any ideas on how to stop it?

Long shot, but a groan or fog-horn noise may be from
a toilet ballcock. One brand in particular would create
vibrations like that as it attempts to close.

To find out: shut off the supply valve(s) to toilets
and see if the groan still occurs.

I had a Fluidmaster toilet valve that would do that. It didn't leak,
but would make an ungodly racket when you flushed the toilet. After I
shut the water off to the house to do repairs elsewhere it got so loud
that I finally broke down and bought a new one, et voila problem
solved. I guess a piece of crud must have been stuck in it somewhere
and was vibrating back and forth as the water flowed through it.

Those floating type water shutoffs have a cleanout feature few people know
about. You turn off the water (duh) crank the top 1/4 turn, set the
mechanism to the side, put a cup over the water outlet, turn the water on
and off a couple of times, wipe your finger around the top rubber seals, and
that will stop a lot of running on. It's in the instructions. (That white
paper that comes in the box.) I have changed at least a dozen of those, and
FINALLY read the instructions on how to clean them out.

It's a male thing.
