Hello everyone. First posting and it's a mystery. Just disconnected all water lines at the hot water tank to drain and winterize water system. Have done this many times before. However, this time a small 3/4" long x 1/2" dia. bullet shaped spring check valve stem with a small "0" ring on one end showed up on the bilge floor without my noticing where it came from. Hot water tank drained quicker than ever so I am thinking that it must have come from the cold water supply connection. Supply line attaches to a 90 degree push in coupler mounted directly to the tank. Anyone ever have this happen and figure out where this stem inserts and in what direction?
