Finding a mystery leak?
April 10, 2011 8:50 AM Subscribe
My house gets its water from a well. I've been noticing the well pump running at odd times, even when water is not being used. As a test, I double checked that all faucets were off, no washer in use etc. Sure enough the gauge on the pressure tank was slowly dropping, at a rate of about 5psi/min. There is no visible leak anywhere. Any suggestions on how I track this down?

I also shut the valve to the well, and to the hot water tank. This did not stop the pressure drop so I've eliminated those as possibilities. If I shut the valve supplying the house cold water, the drop stops.
My house is on a concrete slab and there is no crawlspace or basement underneath. The pipes are well hidden somewhere (run through the slab?).
I am hopeful there is something simple I am overlooking...
