: : My pipes rattle like thunder when no one is using any water. The noise comes once to four times a day and lasts about 30 seconds to a minute. Turning a tap on will stop the noise immediately.

: : We've lived in the house for 6 months, and have only had the problem for about a month. We had an Aprilaire humidifier installed on our furnace around the same time the noise began. However, I have shut it off and the noise has continued.

: : Your help could save a marriage!

: Are you on a well? If so, it could be the well pump recharging the storage tank. Of course then the question is where is the water going between charges?

Sounds like a loose washer somewhere in your system. It could be the house valve if it's a globe pattern and it was shut it off to make the water connection for the humidifier.However it could be in a ballcock, wall hydrant or any faucet. When water is used in the structure a lower pressure can occur which may allow a washer to displace which can 'rattle' back into place after awhile with full pressure.
Are you sure it is not your toilet tank refiling?
