Jabsco Loo info needed

[Robin]

I need to replace the Jabsco loo one evening this week if the weekend is going to be sailing so urgent help needed!

Our existing loo is in a customised area and the pipe from the bowl that goes to the pump actually passes out through a bulkhead and back again to the pump. I have yet to see how accessible the other side is or if the holding tank is fitted up tight to it so I'm trying to get an idea of what is entailed and look at all plan B, C and D options.

How does the connection of the flushing pipe between bowl and pump fit into the bowl? The manual/diagram isn't clear but I think it might be just a tight push fit into the china? I will have to remove the existing one to take out the existing loo I think as it has (according to manual and as seen on the new loo) an elbow which is the wrong side of the bulkhead that is too big for the hole in the wall. Likewise there will a problem with the new set up and getting the elbow back into position. One option therefore would be to leave the existing pipe/elbow in place and disconnect it at both ends, that is if I can just prise it free of the old bowl, and use this connection and pipe again on the new loo??

I'm also thinking of using the existing plastic elbow connection to the outlet pipe and discard the one on the new loo, rather than struggle in a very confined space with heat gun or hot water to connect up to the new one. I suspect otherwise I might have to cut the old one free and would then be a few inches short of hose to reconnect. Any problems with that thinking?

Plan C is to simply transfer the new pump assembly (which is what broke last weekend, cracking across the barrel, I cannot think what SWMBO did to do it but...) and swap the lid/seat over. Before anyone asks the pump assembly cost £50, and new loo was £93 but then I broke the lid as well trying to fix the pump so need a new seat/lid set as well at £30 - makes a new unit the best option as these were in stock locally.

All offers to come and do the work gratefully received!

hmm, plan C sounds quickest/easiest & still renews the vital parts, yes?

The inlet elbow, from memory, is a push fit. I would use remove/cut off the existing hose and use the new elbow on the loo. It will pay you to fit new inlet and outlet hoses as they will be an absolut B***** to get off! And you will find the outlet hose will be extremely hard AND full of 'calcium' deposits.
Much easier and quicker to replace the hoses(with the more expensive 'No Smell' type - well worth it.
Good luck anyway.

Which model?
Is this an electric one or manual?

Don't forget - if you're fitting pipes then heat them up with a hair dryer (or carefully with a heat gun) first ... quick and easy to fit after that (so I found out after 2 hours of swearing at the damm thing! /forums/images/graemlins/blush.gif)

Alternatively, dip the end in a container with boiling water in it.

I'm trying to keep the job to manageable timing if we want to sail not loo build this weekend and replacing the hose is a nightmare job! The hose goes through 3 bulkheads and via an anti-syphon elbow so even if I ignore the holding tank part there are 4 (inaccessible) connections to break and remake! We haven't had any blocking problems yet or smells so replacing the outlet hose isn't an immediate need and might be better left at this stage, at least I keep telling myself that.

Plan C is a definite possibilty if the pump to bowl pipe becomes a time waster!

It's a manual and the compact version.

To others, I know about the heat gun/hot water method but I think if I remove the outlet hose from the existing elbow the end will be too loose on the new one and I'll need to cut some off, even If I could even remove it without cutting some off in the first instance. Hence the idea of using it as is, taking the new elbow off from the new loo and then bolting the old one with hose attached in it's place. I've had that apart already and the elbow is OK and not scaled up, I had already fitted a new joker valve.

If I was doing a quick job prior to the weekend. Plan C.

Sounds like one of those cases where the boat is built around the plumbing with no thought about future repairs and maintenance. The same often goes for wiring. With the time pressure, the easy option is the answer. Buy a new loo, use the pump and seat to get the old one working for the rest of your season and use the winter lay up to do a proper job with new pipes etc. As a veteran pipe wrestler I know it ain't a five minute job and I think you risk having to resort to the bucket if ( Sod's Law applying in spades to anything relating to marine toilets) you try to be more ambitious and it all goes Pete Tong.

Plan C!
That's what I did, I nowadays just buy a new pump anyway, have one as a spare in the locker.

I worked on that joint this summer. I managed to damage it trying to take it apart. There's a large nut on the back (part number 6 on the diagram that I got from somewhere) that squashes a rubber seal to make it a tight fit in the bowl inlet. Loosening that nut at the back of the bowl makes removing the seal without damaging anything a bit easier.
Tightening that nut on reassembly was not easy!
HTH,

In our case the interior was revamped for long term cruising and so Jeanneau can't be blamed, this was an owner conversion. The previous owners had the mods done to add a large holding tank and convert one of the two double stern cabins to additional stowage (known as the 'shed'). At the same time the forward loo was removed and the forecabin double extended aft, creating an owners stateroom/dressing area. It's is all rather nice but last Saturday night/Sunday was a painful reminder of the old bucket and chuckit days! Thankfully the dinghy was stowed on deck and we could get ashore without having to mess with that again. Now I know why twin engines (or 2 loos) are best!

Thanks! I thought that might be the case but even with the new loo sitting here it isn't obvious and it isn't mentioned in the manual. I'm glad I didn't try an exploratory prising off! I think I'll have a quick look at the other side of the bulkhead in case access is easier than I think but then probably adopt plan C with swapping bits over in situ.
