How to Quiet Heating Pipes
This Old House plumbing and heating expert Richard Trethewey shows how to silence noisy heating pipes
1. Raise the temperature on the thermostat to activate the heating boiler. As hot water flows through heating system, listen for creaking, popping sounds.
2. Inspect the hot-water pipes leading from boiler. Check to be sure there's sufficient expansion space where the pipes pass through holes in walls and ceilings.
3. Use pliers to remove any metal strap clamps holding the pipes tightly against joists or other hard surfaces.
4. Replace each metal clamp with a plastic "Mickey" clip. Slip the plastic clip over the pipe and then screw it to the joist.
5. Now move upstairs and check the vertical sections of hot-water pipes that come up through the floor. Slip a plastic clip around each pipe and then press the clip down into the hole to isolate the pipe from the surrounding wood.
