Plumbing making rumbling noise?
Ok, so my toilets were making banigng noises after the tank filled up so I thought I had water hammer so I drained the entire house and opened up all the Faucets to let the air out and the noise is gone. I still have noise when I turn on my kitchen sink as well as my upstairs bathroom sink. Can anyone tell me how to get rid of this or what the problem is? The toilets no longer make the rumble, just the Faucets.
It is - almost for sure - a loose washer somewhere. Either in both fixtures that are rattling, or in a common valve somewhere.
I see it most often in toilet fill valves.
BTW, if you're on city water (as opposed to a well) air is not likely to get in the line. The incoming water is under pressure. If there was an opening, water would go out rather than air getting in.
