Intermittent Noise In Attic After Outside Water Turned On

Open your faucets to drain all of the water from your plumbing system.

Intermittent noise in attic after outside water turned on.

Let the top faucet run until it stops sputtering then turn it off. The incoming water will flush the air out of the pipes but not out of the vertical air chamber where the air supply has been restored. Turn off the water supply to your house at the main supply or street level. The sound can sometimes come and go depending on temperature and humidity levels which makes the belt expand and contract.

At this point the air will be refilled in the air chambers. Open the lowest faucet it s usually outside or in the basement and let all the water drain out. Supply pipe leaks may be continuous and thus are eventually discovered by water stains or mold or intermittent such as a leak around a tub or shower control that drips into the wall cavity only when the valve is turned on. If your boiler is knocking your circulation pump may be on its way out.

We recently noticed the sound of water running in the pipes even when nothing is turned on. Intermittent or constant squealing points to a misaligned or worn fan belt. The water that was rushing toward that exit has a high amount of momentum and when it meets the closed valve causes a loud bang. Water hammers can also result in a series of smaller bangs in your pipes.

If you don t replace a worn fan belt it will eventually break so you run the risk of not having air. What causes the noise. If you see water or water damage call a plumber immediately or a roofer if the water dripping sounds occur only when it is raining and or when there is ice or snow on the roof. First make sure the radiator inlet valve is fully open as a partial opening could result in some noise.

As hot water flows through a cold metal or plastic pipe a process of expansion can cause a rapid ticking sound for approximately 45 seconds followed by slower intermittent ticking as the pipe. We checked through the house the noise stops when the main water line is off and when the hot water is off so we figure it is the cold water line somewhere. If the sound continues the u s. If there is a water leak that water likely would find its way down there.

Air can become trapped in your pipes due to issues in the water line. If you do not find water beneath the location of the dripping sound but the troubling water sound persists conduct a water loss test. A drain piping leak inside of a building cavity can also produce a noise that is hard to track down. Turn the water back on.

Turn the lowest faucet off the one you opened in step 3 and turn the water main back on.
