Re: jabsco electric head problems

Okay, found the problem, block in the line. Now I have a leak where I had to replace a section of hose that was brittle and put in a barb. Does anyone know how to stop a leak coming off of a barb? I cranked it a hard as I could with a clamp, maybe I need to get a ratchet on it or is there some kind of glue I could put on it?

Re: jabsco electric head problems

Ed, replace the whole line. They age and it's just not worth the hassle.

We have 2 of those toilets, and replaced both motors in the last month. I will never buy another Jabsco toilet for one single reason: Some moron has the wrong size o ring in the repair kit. It is just over-sized. To the point that it rarely goes on correctly. Now, normally, it wouldn't pi$$ me off that much - but this is what keeps sewage from leaking into your head. So, you have to take it apart again (water - if you are lucky - everywhere) and try and make it seal again. Typicall takes 2 - 5 tries.

What really ticks me off is that Jabsco has failed to respond to this, even though I've called and emailed them repeatedly. Conversely, Raritan has been just outstanding in dealing with minor issues we've had with our Purasan unit.

Next head will be a Raritan.

Re: jabsco electric head problems

I agree, but instead of paying Jabsco $400 for that whole part I found a replacement for $100 TMC. They got the gasket right. As for the barb, it's only temporary until I get the little piece to replace the one that is broken off where the joker valve is. It gets brittle and breaks when you move the head for repairs. I have two also and am hoping I don't have to replace both of them.

Hope this link works-it's the one I found on ebay. It's sold by five oceans and they have a 10 percent off deal until the end of Jan. the code is fiveoceans675 for the discount. This is a much better unit, it actually works. Shame on Jabsco. The only thing is yo have to convert the in and out from 5/8ths to 1 inch if you have a 5/8 Jabsco head.

Re: jabsco electric head problems

It may be sacrilege but I use RTV. That stupid Jabsco o-ring is the wrong size and even if you can get in in place dry it will inevitably slip out on assembly. RTV may be the lazy man's solution but it works.

White vinegar flushed regularly will help prevent the line plugs. If it will still pump out then a gallon of white vinegar will do wonders. If it has gone past where white vinegar will pump relatively freely then it is time for more severe actions - muriatic acid works.

Re: jabsco electric head problems

Room temperature vulcanizing
Otherwise known as silicone caulk to most people

Re: jabsco electric head problems

Do yo mean you put it around the edge of the motor where it mounts to the toilet instead of the gasket? I think that would work. Would you use 5200?

Yes to the location. And no to the 5200 - I use blue or black RTV - whichever I happen to have on hand. And no, I don't know what the difference is between black and blue other than colour.

Re: jabsco electric head problems

After spending a lot repairing the Jabsco , I replaced it with a fiveocean unit, cheaper and worked flawlessly for the past two years, live aboard full time

Re: jabsco electric head problems

My head is filling up with seawater, what's wrong with it? It's the electric Jabscio quiet flush, that isn't so quiet.

Re: jabsco electric head problems

Bet it's the joker valve. Pull it out and clean it or better yet replace it. All heads need a little love every year. I put a new motor on mine last year it is much quieter.

It depends what you mean by "filling up with seawater". If you mean water is entering when you're not using it then I'd blame the joker valve too. On the other hand if you mean that when you flush, the water comes into the bowl faster than it gets pumped out, then there's a couple of possibilities. You may need a pump rebuild or need to clean the macerator impeller. Or you may have some restricted or plugged lines.
