The plumber who came over to fix my boiler and bleed the system reiterated to me a few times that the pressure on the boiler should not exceed 20psi. Well, what do you know .. it did tonight at 4am. Luckily I was awake and heard water dripping from the boiler -- so I went to check. Apparently, it had gotten to 30psi and water was coming out from the pipe connected to the reducing/relief feeder. Turns out he had set the temperature to 190-200. Weird thing was that the system had been running all day on that temperature and it didn't happen till 4am. So, I lowered it to 180 degrees and I see it now goes up to 24psi about. Is this still too high? I read a few threads where njtrooper said 180 at 24psi is fine. I've been watching the boiler turn on/off for the last hour and the maximum has been 24/25psi before it turns off. Now, here's the other weird thing ... as I'm writing this message -- it turned on again and I went to watch it. It only went up to 21psi this time ... I did readjust the temperature to be exactly on 180 (whereas before it may have been slightly off at 179 or so).

I have a Weil McLain GV-4 Series 2 boiler that short cycles. Even though there is a call for heat the gas valve only stays open for about 3 minutes. The water temp. is not getting above 140 degrees. I have set the thermostat anticipators at .9. any suggestions?:wall:
