Can anyone help. I have a boiler that is running about 30 psi and I know the pressure should be about 10 psi. I bled the valves on all the radiators. Also, near the boiler just above the boiler where there is an L there is a air vent that is leaking. Could the problem be a simple as replacing that air vent. Thanks for any help.

With the pressure in the boiler running @ 30psi, there are a few things that may be wrong: Expansion tank is full
water feed valve is leaking by
Take some water out of the boiler at the drain cock and lower the pressure to 10 psi. Allow the boiler to operate and see if the pressure rises again. If it does this can be an indication of a full expansion tank.
