Re: Water pipes rumbling !!
If this "rumbling" sound is heard while using water and not as the water is suddenly turned off then it may be from a few things.. .......Depending on the sound that's being heard.
If it only happens when using a certain faucet the faucet washer may be loose or damaged causing the sounds .
Try tightening the screw the washer in the faucet stem. If the problem stops and later returns, then it's time for a new stem assembly.
If it's more of a moaning , humming,or fog horn sound .....
A faulty diaphram inside the toilet ballcock (fill valve) will cause resonance sounds like these.
Here's an easy way to tell if this is the cause...........
Close the supply valves to all the toilets. If the noise disappears, open them one-by-one till the noise starts again. Replace the ballcock in that toilet.
High water pressure can cause a variety of problems including noises..... also damage toilet valves and other devices connected to the plumbing.
If you're on a city water system, ask your neighbors if they are having similar problems. Some city water systems have higher pressures in the main lines and may have pressure reducers between the main line and your house, at the meter. In this case, if the pressure regulator is defective you could have high pressure even if your neighbors don't.
If your pressure is above 60psi you may want to adjust your pressure reducer or install one.
You may have a regulator installed inside the home already and may be a problem with the pressure regulator if your sound happens while the water's running :
While the noise is happening, check to see if it seems to be coming from the regulator. If so, the regulator may need to be replaced.
- it happens at more than one faucet
- turning on other faucets changes the tone
- the pressure changes with the sound
If you have a well you probably have a water pressure meter.... check to make sure it isn't more than 60 psi.
Just some thoughts.
