Could I have installed the Base Valve Gasket
Help, I can not sail until this issue is corrected.
There are two positions on the Pump Head
. One for "Flushing" in which case as you activate the pump, raw water
is drawn in, distributed around the rim of the bowl and evacuated from the base of the bowl with repeated "pumps". The Second position is for "Dry Bowl" in which case pumping drains the waster/water in the bowl but does not introduce any additional raw water
such that only a small amount of water
remains in the tube under the bowl once it's been emptied. If the foregoing is not what you are experiencing, you may have, in fact, inverted the gasket in the base of the pump. Properly installed, the round weight should be on top of the "flapper valve" seal.
