We have single-pipe steam in our four unit building. We installed Danfoss RA 2000 valves in 3 of the 4 apartments but they seemed not to work too well and also tended to spit water from the air valves.
The system was running around 3-5 PSI. I turned it down to 0-2 PSI. After doing that however I noticed the water level in the boiler slowly rising and now it flooded. Any idea why that would happen? Am I stuck with higher pressure?
I have the Danfoss controls for 1 pipe steam. (My radiators stopped heating consistentenly, so I put a Hoffman vent on one of the radiators.) The rest are Danfoss vents.
As for the boiler flooding... looks like my Pressuretrol tripped? The mercury bulb tipped over and opened the circuit.
I drained the boiler until the sight glass was 1/2 way and pressed the lever and the boiler turned on again. But it keeps tripping. Sorry if I'm not using the right terminology.
The water in the glass moved higher and seems to be hovering around 3/4 full. (It visibly oscillates up and down slightly when the boiler is on but I assume that's normal?)
I am attaching picture(s) of my boiler controls maybe you guys can see what's wrong...
I don't know how to adjust these controls to try to keep the pressure below 2-3 PSI.
