 Pipe vibration
Author: ramonekalsaw (WA)

Hello ... another post on vibrating pipes ... but apparently not water hammer.

When the temperature outside drops i've been getting regular, in that it's been happening for over several months now, but intermittent, in that it doesn't happen everyday ... but MYSTERIOUS ... because it only happens when i'm not running water. And generally, when water has not been used for quite a while.

I'm typing at the computer and all of a sudden i hear a loud vibration in the pipes under the house where the water comes into the pressure tank. At least it's in that area.

Can anyone shed any light on this? It's quite unsettling and i'd like to know as much as i can before i get a plumber involved or if i have to.

You're probably hearing the pump kick off. The check valve, depending on it's location and style, can cause a pretty decent vibration on your piping. As Packy said, you should check your toilet tanks, as a slow leak there will cause the pump to cycle, even though you're not "using" any water.

Check valves will "chatter" when the pump is running and pushing water thru them. You are less likely to hear it when you are actually using water (shower, sink, etc.) than when all is quiet around you and a toilet "calls" for water refill. If this is the case, your only concern is with the toilet tank losing water.
