I have steam heat mostly radiators but in a bathroom I have a small section of baseboard Black pipe with the fins around it. On the end I placed a veri valve, which can be fully opened or closed.. A few times when the heat is turned on and the pressue builds, alot of water comes out of the valve. I know this should not be. I have drained some water out of the system and that seems to have stopped it, but occasionally a small amount will still come out. Do I need to have a relief valve there, can I just cap the end. Any solutions.
