High Water Pressure
Posted by Marc E. Brown on September 19, 1998 at 11:39:16:
My residential water pressure in LA should be about 55 psi. But when the water is shut off, it creeps up to about 140 psi aftr about 3 minutes.

Is this normal or do I have a regulator problem? I am using a Wilkins 600 regulator.
