Jabsco manual toilet issue

Congratulations on the shortest video I've seen!

There is an O ring to stop water coming out past the shaft. Replacing this should solve the problem.
 
Please see the link below to a video I took. Water seeping up when pumping!

Any ideas of the cause/fix?

Thanks.

I can't see the video but, every time I took a jabsco toilet pump apart, armed with a full service kit, it always leaked. In the end I bought two new pump bits for about £60 each, (2009), for the two toilets.

I sold the boat but, if I ever had another Jabsco loo, I'd replace the whole pump, rather than try and fix bits.

We are just fitting a brand new TwistN'lock Jabsco and will buy a complete new pump assembly To carry as a spare on board. We inherited a manual jabsco that had the electric convrrsion kit fitted and which leaks, Decided to go back to KISS principles and revert to manual

Looks like you need a new spindle seal Jabsco part 29044-3000. The twist and lock seals (made in China) don't last as long as the older pump types.

I had the same problem with the older model (circa. 1980) and removed the seal to get the part number. I bought a half dozen seals from Bearing Services for a pittance and they lasted for a long time.

I'd assumed I'd need to do the same with the new Jabsco units but part in link actually looks like quite good value. If I'd had to guess a price I'd have said it was worth about £6 but would cost £12-£15. I think I might grab a couple as spares, thanks for the link.

When (if) you put in a new seal, if there is any crud, scale or rust on the shaft, clean it off and make the shaft shiny and smooth. If you don't or can't, the seal will just chew up again in no time.

And a smear of lubricant. Also, when you grip the shaft with pliers/mole grips etc. to be able to unscrew the handle, do it right at the top and wrap with a rag to avoid damage to the shaft.

Living aboard 9-10/12 I've found I have to change them annually. The seal bit, no doubt costing pence, is well embedded in the plastic and I've not managed to get one out without damage.
