I purchased a hot water tank about a year ago and had it installed. I noticed the other day that the pressure release has water comming down the pipe. It looks like it is constantly draining. My question is what could be wrong? The place i bought it from (Lowes) tells me it a water pressure regulator and has nothing to do with the tank and wont come and look at it.
What is a water pressure regulator and is this a valid reason for this problem or are they trying to get out of living up to theri end of the warrenty?
