t&p valve ???
Posted by John on December 07, 1999 at 09:11:55:
I have a hot water baseboard heating system. I recently replaced a section of BB during a remodeling project. Afterwards I purged the system and turned on the boiler. At that time the pressure in the system when up very high and the t&p valve released. After it released it seemed to be working OK. The pressure would be around 20 psi @ 180 F when running. That was a few weeks back. Last night I notice that the t&p must have released again since there was water on the floor and the pipe from the valve was dripping. I put a bucket underneath and it had an inch or two of water in it this morning. What could be causing this? The system has a PRV, backflow preventer and expansion tank which I installed a couple years ago.
