Anyone have any ideas why my pipes start whining when water's run only
in the winter (when the hose bibs are winterized?) It's a
medium-pitched whine with a little vibration. House is a 6 year old
three level townhouse built by Centex. Thanks.


I've heard similar sounds from vacuum breakers, but can't say if that has anything to do
with your situation...
