if you're hearing a long and loud groan even when not using the water at
nite, you'd best be looking somewhere's besides the plumbing.

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
getting more frequent and loud and actaully will occur when we are not
even using a tap i.e. during the night. Right now it is happening
while we do the laundry. Any ideas on how to stop it?
