This is highly odd. I can not figure out the cause, but I suspect a check valve. A very loud noise which actually vibrates the house a little occurs in the plumbing once in a while.

I have noticed that there is a relationship with when the pump starts and stops. I can here the click of the relay. I'm not sure if it occurs when the pumping begins or ends though.

The plumbing in the house goes:
line from pump -> check valve -> pressure tank -> house.

Is this just a problem with the check valve? The tank holds pressure fine, but maybe 10 years has cought up with something?

Just to clarify, I have in in-well pump.

I've also read that similar noises may occur due to a leaky flap valve in my toilet (whic his lekaing slightly).

I can not isolate where the noise is coming from.

The noise starts quiet, gets loud then quiets down again. Maybe a 5 second duration.

As an addition to this.

The noise can occur at anytime. It's happened while showering, after flushing hte toilet, while sleeping at 4 am. It's loud enough to wake you up! Or just when sitting around doing nothing.

Thanks again,

I should add that I suspect that the noise occurs when the pump stops, but I can not verify this.

Maybe the pressure tank has to little or to much air in it.

Sorry for the 3 posts. This is somewhat urgent seeing that my house is for sale and the noise just started recently (1-2 weeks ago).
