Purged air from hydronic baseboard heat system, now pressure relief is leaking! HELP!
A couple days ago I posted this thread, over here. I was set straight on how to purge the air from my pipes after I did some work on the system.
However, after using the manual fill lever on my auto-fill valve and letting the system drain and push the air out of the system my pressure relief valve has started to leak. Unfortunately its a pretty steady drip coming from the pipe.
The pressure shown on the front of the boiler is the same as it was after I purged the system. I made sure the manual fill lever was put back in the off position. I've even tried bleeding off just a small amount of water from the purge valves trying to see if that would help, but the auto-fill keeps kicking in to maintain pressure.
Could the relief valve have failed just from the purge process? Am I over-pressure for the system? Any help you can give is appreciated!
