I had a leaky seal that I replaced on my recirculator pump. I drained the water from my system and everything went pretty well. There is no leak anymore and the pump works fine. The issue I have is filling the system back up with water. I open the cold water supply valve and filled the system. When I did that the pressure relief valve popped due to the high water pressure. It released a lot of water. Now that I am using the system, I hear the water filling my baseboard units every time the pump comes on. I replaced the pressure relief valve with a new one. Should I simply bleed the air out of my baseboard units? How do I know if there is enough water in the system?
Any info is appreciated.
