Re: Hot Water system Circulation Issues
Zone valves and a flow check should never be together on the same system. You can manually open the flow check by turning the lever on top and leaving it that way.
However, I doubt if that’s your main issue. You’re either air bound or the zone valves are not opening. I’m assuming your circulator is pumping in the right direction.

Re: LP boiler Shuts off completely after reaching room temp
Something is still not right. That is a standing pilot gas valve, there is no connection between the pilot and the controls. There's no way for the aquastat to kill the pilot flame.

Re: Corroded connectors on new boiler.
Two disimliner metals but it is ok. Take them apart clean them up and put back together. Do it befor it gets worse.
Re: Hot Water system Circulation Issues
If you have zone valves then that red flow control valve serves no purpose at all. The circulator shouldn't be buzzing, it should be silent.
Re: Hot Water system Circulation Issues
most often when you open a system, to replace a pump for example, you need to purge both zones. A single air bubble can stop circulation.
What does the pressure gauge read?

Re: steam radiators are hissing loudly and spraying hot water/steam
I feel the caps on the Hoffman 1As were an embarrassment. The fit was so sloppy the numbers were completely useless.

Re: New NYC steam radiator inspection law - what does it mean?
The way I see it, it may push tenants with children to rent in a much worse environment for their children. The end result may be a greater loss. Time will tell.

Re: Main vent hissing steam at end of cycle on new Gorton #1 vent
All I am saying is that it is quick and easy test to determine if a vent has failed, not prove that it is good. That is two different things. If it fails the blow test it is bad, either stuck closed or stuck open. I had one out of the box that failed this test and I sent it back and got a new one.
