Hi I hope someone can help me with an unpleasant issue! I have tried to search the forums with no success and it difficult to find the right search terms !

So when we got our new to us boat the toilet, manual jabsco twist and lock type, was backfilling with waste after use, also the pumping was pretty weak.A bit of reading later I purchased A full service kit , fitted it carefully and cleaned everything as I went. All good so far. The backfilling problem has gone, flush now much better and the smell is improved.

All good I thought! However here is the unpleasant bit, if you have a poo when you switch to left and pump in water bits of chopped up poo now flush back into the bowl from under the rim at the top, with the water ! It clears itself after a good pumping but the my wife is going to be less than impressed! Fortunately she hasn’t used this function yet but it’s only a matter of time !

What did I do wrong? I was really careful to follow the instructions but I must have missed something,

Any advice gratefully received !

Thanks
 
The only way bit of waste can get in to the flush water is if they're flowing past the piston in the pump. Did you replace the O-ring on the piston?

Are you sure it's chopped-up poo? Could it be debris from the inside of the pipe from the inlet seacock?

I was getting that issue but that seems to have stopped and I’m pretty sure it’s poo. I will check better next time. All is fine if you just pump water through the toilet so if it was from the inlet presumably I would have the issue all the time?

There is quite a bit of it and it carry’s on for a while, it must be a pretty bad seal in the piston if it’s all getting passed. The pump works well pumping water so I would be surprised if the seal isn’t sealing but as you say it must be getting from the bottom of the unit to the top somehow!
 
Where are the inlet and outlet in the hull? On our previous boat the inlet was only about 2 ft ahead of the outlet. No problem if the current under the boat was “normal” I.e. from bow to stern, but in some marinas this can change with the tide and we learned to be careful to wait some time between pumping out and flushing to avoid unpleasant recirculating.

Good thought.
 
I got some liquid mud into ours once, forgot we were in a "drying" berth...

Some got trapped in the rim, took ages (most of the season) before it was completely clear again.

I wonder if he has a holding tank and wonder if it is open or closed?

We have a holding tank, simple arrangement with everything always going through the tank. It’s a good thought about the inlet and outlet they are next to each other just aft of the toilet. The tank is aft of that all with the correct loops etc. Boat is a Jeanneau 32i if it helps
 
Sorry should

sorry should have added I have only tried this with the main outlet open, next time I require a “movement “ I will try with outlet shut!

If you have a spare bit of hose, stick one end into a bucket of fresh water and connect the other to the pump and see what appears.

Good idea thanks

You pump out in a marina?

No I was out at sea when I tested it, we have only just got this boat after selling our previous one and hence haven’t used it much yet. I tend to use the Marina toilets so no use when on the mooring
 
Just a thought. Unpleasant bits in the flush water may not be pooh: they may be algae/bacteria growing on the surface of the inlet pipe. Using the toilet for the first time in ages has loosened the coating and that’s what you’re seeing in the bowl. It’ll look remarkably like sh1t: black and flakey, but it’s not the genuine article....
If you head was smelly, that’s the algae/bacteria breaking down in the pipe giving rise to the typical bad eggs smell. A good dose of pumping will get rid of the pong and a protracted bout of pumping with a good deal of elbow grease will shift the black stuff.
