Jabsco Toilet Question

[Stemar]

I have an RM toilet that's about 10 years old. The rubber connectors that connect the flush water and basin drain to the bowl are both past their best and leaking and the pump's getting tired. Until recently, parts were unavailable, so my only choice when bodges can't keep it going was a replacement. Parts are now available, but at slightly eye-watering prices. £12 for the pair of connectors and £40-odd for a repair kit - half the price of a new Jabsco. If I need a new pump, I'm within a few pounds of the cost of a new bog and I've still got an old one with little faith in the continued availability of spares.

One factor is that the wash basin drains into the head via its own connection into the pan. Does the Jabsco Compact have a separate inlet for this? I seem to remember the knackered old thing (Par Brydon?) that was on board when I bought the boat was installed so the basin drain went into a Y connector on the inlet pipe and enthusiatic pumping sent flush water up into the basin, which I'd rather avoid.

If there's only the one inlet on the Jabsco, does anyone have any suggestions as to how to prevent flush water going up the drain pipe? I'd rather not install a separate drain & seacock and I doubt that gravity would push water from the basin through a non-return valve.

Any other considerations that might influence my repair/replace decision?

Check valve? The jabsco doesn't have a separate connection for wash basin..

I'm no expert but how about putting the non return valve in the heads inlet pipe, upstream of the sink outlet?

Whatever you do, keep in the back of your mind that RM went belly up no too long ago. So spares are only those still present at shops and the distribution channel. I don't think the RM brand will have a restart anywhere soon.

Speaking to my local chandler, it appears that they're now resurrected, but I do have to wonder for how long. Also, Jabsco parts seem to be around 2/3 the price of RM stuff if I need them in the future, so I'm definitely leaning towards replacement. I just have to figure out a way to stop flush water going up the basin drain. I can't see how any sort of valve would work as the head of water in the drain wouldn't be more than about a foot. Maybe I'll just put a Y piece in and see how I get on. If it's too bad, I'll just have to put another hole in the boat. The things I do for SWMBO...

A ball valve in the sink drain would do, surely? Not terribly convenient but then I don't suppose the sink is used all that often?

I take it pushing the sink plug in firmly is not good enough ?

A valve ( ballvalve) in the sink drain would do it provided you can position it so that its accessible or operated remotely, like basin drains on posh basins . The plug then becomes redundant 'cos the valve would perform the same function, then just open it to drain and rinse the basin and close it again.

Oh beaten to it by Vyv!
It shows how great minds work alike though.

Good idea Vic & Viv - Thanks. I'll have to see what I can do to make it agreeable to SWMBO, she's the arbiter of what's acceptable

Don't go sticking baby wipes anywhere near it. :disgust:

Quite. It's well understood on Jissel that anyone who does will be swimming home

If you are in the SWales area I am selling a jabsco toilet that I took out of a small boat, I think its less than a year old, according to the owner, it certainly looks new, £35.

I saw your advert, but I'm London based (boat in Gosport) and, unfortunately have no plans involving anywhere west of there. If you're coming anywhere near either in the next couple of months, I'd gladly relieve you of it.

A few years back, about thirty I suspect, I saw a drain made for the sink on a MFV which consisted of a piece of flattened copper pipe which was bent over the edge of the porcelain at the back of the toilet and under the seat. It was only visible when the seat was lifted for various standing tasks. I was surprised as it looked 'Heath Robinson' but it did the job very well since it only carried away soapy water.

Now that looks like an idea worth trying - thanks
