Moen balancing valve?
Posted by George on February 02, 2004 at 15:16:54:

I have what appears to be some type of moen tub/shower balacing/mixing valve that the flow has become very low. (Just replaced the water heater) The device uses a standard moen one piece cartridge. Its not exactly like a picture of a Moentrol, mine has the two Stop-Check valves on either side of the cartride opening. Two small pipe plugs (1/8"?)just below these on the brass body. There is a plug just above the cartridge opening with large standard screwdriver slot, (about .75" wide)
Should I just try taking out the check valves and the slotted plug to clean out any rust flakes? What does the center plug with slot cover/do?
Thank you in advance!
