Clanging Pipes

When faucet, shower, or clothes washer is turned on pipes clang & bang, and for about a second no water flows. Heating system is a tankless, hot water by oil, and the house was built sometime during the 1960's.

Sounds like you need to install air arrest or valve- these were demonstrated on ask this old house.

Re: Clanging Pipes

I have the same type of problem when I turn on the washer, sink faucet, or shower located on the other side of the house. The pipes run across the attic from the hot water heater which is located in the garage. The pipes clang, moan, groan, or thump until hot water gets to the other side of the house. The house was built in the 70s. Replaced the hot water heater 5 years ago, turned down the water pressure, opened the relief valve on the heater many times, and the problem is still there. The noise happens near the living rooms in the attic. Any ideas or help?
