Boiler Expansion Tank Shut Off Valve at Brock Kleeberg blog

Boiler Expansion Tank Shut Off Valve. Then open the drain valve on the tank. Close the expansion tank drain valve. Open the isolating valve between the expansion tank and the heating boiler or heating boiler piping (photo below left). Pressure relief valves especially come into the equation when someone has a boiler pressure dropping causing it to turn off and central. You will doubtless hear some water. Shut off the boiler for about 30 minutes to let the system cool down. If that hole is blocked, the pressure can not be compensated by the expansion tank but must be released by the pressure relief. Test for waterlogged conventional (bladderless) heating boiler expansion tank: The reducing valve (what i call an autofill valve) adds water to the boiler loop when boiler pressure falls below its setpoint. First, shut the valve between the tank and the boiler, or the rest of the system. Expansion tanks are necessary to accommodate the expansion of water in hydronic heating systems. They rely on an internal air cushion that compresses as the system water heats up and expands, thus keeping the system properly pressurized at all times, regardless of temperature.
