This video goes into how the pressure reducing valve works on a hydronic system. It also discusses the pros and cons of keeping the valve open or closed on the incoming pipe. Hope you enjoy it.

    I was taught to leave the water off. That way you'll know if you have a leak. Continuously adding water is never a good thing.

  • There's another cause for increasing pressure, which I'm sure Mr. Wohlfarth, with his long experience, has encountered. That would be a pinhole or leak in a tankless coil or the hydronic heating coil in an indirect water heater. I've experienced both at one time or another. This allows domestic water system pressure-which can be as high as 60 psi-to pressurize the closed hydronic system to the point where the relief valve opens.
