Leak

[highlandlass]

Hi would a small leak in my hall radiator cause constant pressure drops?

Yes not much water would have to come out for the pressure to drop.

Thank you! Time for a new radiator but at least i know why the pressure drops. Thought it might have been a more major issue.

Well the hope would be there is no other leaks. When the pressure was dropping on mine only a minimal amount of water was coming out the PRV valve and the pressure dropped quite quickly in a short time.

Turn the valves off either end of the problem rad, and see if the pressure remains constant. If it does, new rad needed. If it doesn't, you've another issue.
