Jabsco Flushing Issue

Good afternoon,

I just completed installing a new Jabsco pump cylinder on my Jabsco Model 29090 manual marine toilet. When I switch the selector tab to " fill" the pump works correctly.
However, when I switch the selector tab to " flush" , the bowl does not empty.
Could I have installed the Base Valve Gasket upside down?
Help, I can not sail until this issue is corrected.

The bowl doesn't normally empty when is in "flush".

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.


FWIW...

I think you'll find the solution to your problem in the owners manual Jabsco 29090 conversion owners manual See the operating instructions on p.3

The Jabsco 29090 is a conversion that replaces a manual pump with an electric pump...no pumping required. Jabsco 29090 Electric Toilet Conversion Kit

Re: Jabsco Flushing Issue

By strange coincidence, today, 3 hours ago, I installed a new jabsco pump on my aft head. The weight definitely goes up. That is to say the bump is on top.
At least I did it that way and it works correctly.
I am usually a rebuild person but the pump was 10 USD more than the rebuild kit.

Re: Jabsco Flushing Issue

I know a bunch of people who replace Jabsco manual pumps annually as part of spring recommissioning. They never even consider rebuilding for the same reason you didn't, plus removing and replacing a few bolts and a couple hoses is a LOT easier!
