Very basic question:
I just bought a Gorton No 1 to replace an older, mis-sized Hoffman as a main vent. It was delivered today and it leaks a lot of steam from the vent hole even when fully heated. It seems to stop hissing when the low pressure gauge reads 1.5psi but as soon as pressure drops it hisses again.
I have had this happen in the past and a new vent fixes the issue.
Is this a faulty vent? I have a hard time believing that a brand new vent would be faulty but maybe rough shipping displaced the valve stem or seat?
