On our 508 we have Jabsco Deluxe Flush E-Toilets. After use and rinsing they start filling up again after about half an hour. Does anybody know where to search for the issue? Is it a leaking valve of the blackwater tank or is it coming from the toilet gear directly? (sorry for the pic)

I have Jabsco Liteflush but usually changing the joker valves resolves this for me.

Normally the Jabsco toilet backing up is the joker valve which is pretty simple to change, just two screws to gain access. Lots of YouTube videos on the prcess well worth watching first. Good luck!

Hi Tobo

Just lived this situation.......Joker valve.........on our electric toilet, it is part number Jabsco 29092-1000.And yes easy job.

We flushed 2-3 buckets of luke warm water to clean pipes before changing valve.

Agree it is the Joker Valve and generally easy to replace.  Just watch it when you screw it all back together as sometimes it can be a tight fit and you are only screwing into the plastic fitting so it is easy to strip the thread.

It looks like an easy job but the bowl is fixed to the wall with Sicaflex. For a world leading company it is a shame that these valves don't hold not even two seasons. Even the fact that you have to demount the bowl to fix the screws for the toilet seat deserves the price for most unfriendly customer service solution! And if you have to flush at night you wake up the whole crew! Noise insulation is a strange word to Jabsco.

So I'm really thinking of throwing these e-toilets out (there are three of them) and exchanging them with Tecma (Osculati) types. We had it on our 470 with no issues for at least six years. What is your opinion?

Iím not a fan of Jabsco either. But all toilets with a Joker Valve arw susceptible to this kind of leak. The valve usually doesnít fail in the way you think, it usually gets mineral build up from urine and sea water, and the buildup causes it not to seal properly. This can be fixed by flushing a bit of muriatic acid (a.k.a. hydrochloric acid, available at hardware stores) down the toilet. If you have heavy buildup, it will take several rounds of treatment. I have fixed leaky joker valves this way many times.

In the future, build up can be mitigated by flushing with more water so urine does not sit against the valve, switching to freshwater flushing (seawater causes more buildup than fresh) and if if you donít want to do those things, treat with muriatic acid once a month or as required.

I have the same issue reported above. However, I could find no videos describing the replacement of the joker valve in an electric toilet. Am I wrong? Suggestions?

Won't muriatic acid damage the bowl, or other toilet parts? Do you have a suggested concentration, or you pour it pure from the bottle directly into the hole?

Muriatic Acid does not react with any of the parts in my jabsco manual toilet, plastic hoses, and plastic holding tank. I *do not* vouch for other types of toilets including your electric Jabsco.  But most ceramic and plastics are immune to this acid. I put about 0.5 liter full strength into the toilet along with about 1 L water, flush half, and wait 20 min or so, then repeat. If you have heavy build up it may take several times. Do wear goggles and gloves, it can seriously burn you.

That's a very good tip, thanks a lot. I will ask the pros in Lagos when we go to winter hard stay.
