Boiler Pump - Flow Direction
Posted by Tim Bradley on September 11, 19100 at 20:03:57:
While replacing some valves on my boiler heating system I opted to also replace the circulating pump gaskets, which were in rather sad condition. Now that cool weather is approaching I believe it's time to finish what I began several months ago. My problem; I can't remember which direction the pump is supposed to flow! Should the direction of flow proceed into the boiler from the pipes or visa versa? There are two sets of pipes (headers) which enter the boiler. One header system has the thermostatically controlled valves, located @ 2' above the boiler, and the other header is directly connected to the pump which is affixed to the boiler. I could ask my wife for advice but then I'd have to go in for therapy. Help!
