Intermittently, I hear a low, vibrating noise after shutting off the water. It first occured after the shower was shut off. Now it happens after the washer shuts off. Yesterday I heard it happen all of its own for a few seconds. If I turn on a faucet the vibrations will stop, then return after I shut off the faucet. After a couple of minutes it will stop completely. When it is happening, I can feel a slight vibration in the faucet when I touch it. I feel it from any faucet – upstairs or down. Note that this will happen for days, then go away completely for a few weeks and then come back. Any idea what is happening?
It sounds like to me you have lots of water pressure and have a loose washer in the faucet which intern viabrates when turned on, turn on faucet on fix and and let run then reach under fix and turn off stop and see if it stops, let me know. Some of the pipes might have to be fasten to joist.
