Need help fast please re hydronic boiler water supply and backflow
Yuri, yes I also have a smaller valve downstream of where the backflow was, which I know is a pressure regulator (this regulator also has an arrow so it can only point towards the boiler). Before this issue occurred, the water supply was always kept on to the backflow, then to the pressure valve and then to the boiler. I suspect the boiler then was able to accept new water when and if needed.
Since my setup appears as being the newer type that does not require manual filling, I assume I'm OK with just turning off the water supply until I get a new backflow. Just in case, I will turn on the water supply for 5 minutes daily just in case the boiler needs more water.
As for the backflow though, can I get a cheap $20 unit with one test valve, or do I need a bigger unit like the Watts 009QT I currently have. Will pictures help?
