Plumbing/waterlines/noise
I hear a sound that I think is coming from the waterlines.What is causing this and how do I correct it.

What kind of sound is it... and do you have a boiler heating system?

To check to see if you have a hidden leak first shut down everything in the house, no flush, no drinks of water, and if you are on a meter go out and check the little pointer in the gage. It should not move or creep. If it does you have a leak. If you're on a pump then check the pressure gage after the pump builds up to pressure and shuts off. The gage should not fall and the pump come back on. If so then you have a leak. Hope this helps and thank you for rating my reply, Tom
