We are selling our house and the buyers did the home inspection. We have been told that the extending pressure relief valve to exterior of garage has a slight leak from pressure relief valve. What is that and how much might that run me in Columbia S.C. to fix?

Hi Jamie:

A few questions before I can offer answers.

I am figuring that this is a T&P valve (temperature and pressure relief valve associated with a WATER HEATER, Or is this a pressure relief valve from a HEATING (BOILER) SYSTEM?).

Also, do you have a sprinkler system or a recirculating hot water line.. I am wondering if have expansion issues?

Answer those questions... see what we can do.

Talk soon... Mark

Two solutions come to mind. 1) If Massplumbers question,
do you have a sprinkler system or a recirculating hot water line? ( or a check valve/ backflow preventer)is yes then you need a expansion tank installed on the water heaters cold water supply. **or** 2) There may simply be a small piece of trash caught under the seat of the T&P valve. Jiggle the handle and see if the leak doesn't stop.
If all else fails then just replace the valve. Good luck, Tom
