Need help with a pressure problem. Two floor house with four heating loops. My hot water heating system is 4 yrs. old and has been fine until a few weeks ago. I checked the pressure gage and it read about 50 psi. Turned off the boiler and jiggles the high pressure valve and wosh it dumped water on the floor. Must have been stuck since it is supposed to go off at 30 psi.. Since then service people put in a new fill regulator valve and closed the fill line valve but pressure is still eratic. I drained out several pails of water just to try to maintain about 10 psi when operating. Then a new vent valve was put in. But the pressure still keeps climbing when the boiler gets hot and i'm still draining about 1/2 pail every day. Repair guys don't seem to know what to do. I'd appreciate any guidance. snipped-for-privacy@aol.com
