Jabsco Manual Toilet Not Bringing Water In.

Jabsco Manual Head. Models 29090-2000 29120-2000

First purchased in 2002.

Jabsco Manual Toilet Not Bringing Water In.

I'm miffed.

1) Replaced Joker Valve
2) Replaced Base Valve Gasket
3) Replaced Piston, Rod & 'O' Ring
4) Lubricated Piston "O" Ring
5) Replaced Top Valve Gasket

Completely disassembled and re-assembled the Head twice. I also watched all the "How To" videos on the Jabsco Site. http://jabscotech.com

I did find a leak in the hose where it enters the head pump from the seacock, but replaced that hose.

With the inlet seacock open and the switch on the head in the "draw in water" position, nothing comes in. I have tried filling the bowl with water to prime it, but still no water. Could my seacock valve be bad? I do hear water splashing under the hull when I operate the pump.

Any help would be appreciated.

If you disconnect the intake hose from the head and open the through hull does sea water come in rapidly? Wondering if something is clogging the through hull or intake hose.

Thanks Paul, no I haven't yet. Just talked to my old mechanic and he said the same thing. I have given in and my old mechanic will be meeting me at the boat tonight. Guess I should have checked the obvious, but I am going to have the Pro give it his blessing. Thanks Paul I hope that's all it is.

Proven Fixit technique

Jeff, if you get frustrated enough...
I find that the best way to "fix" a Jabsco manual head is to remove it, hold it about 2' beyond the edge of your boat, and release it back into the wild.
Remember that tranquility can be achieved - sometimes - by "letting things go!"
:rolleyes:

Tongue in cheek, but not completely,

But Loren, I have already enjoyed 12 years of frustration with my old Jabby. What would I do then? :confused:

Jabsco water issue.

Jeff, With the understanding that your mechanic will be dropping by later today, I still want to share a thought with you as regards "I do hear water splashing under the hull when I operate the pump", that suggests to me that you might be hearing air bubbles emerging from the through hull. Is there anything you can think of to account for the pump functioning in the reverse direction? FYI, I have a completely rebuilt Groco Model K-H sitting in the garage and ready to go should you decide to change out your present one. The Groco K-H and WIlcox Crittenden Skipper II heads have a reputation for being the last heads you'll ever have to buy and I can attest to that in both cases. The Groco used to be in our boat up until about two years ago when for reasons not relevant in their discussion or making any sense in my own noggin, I bought and rebuilt the Skipper II which we now use aboard. I'd venture to say that I could let the Groco go for far less than the cost of a new Jabsco. Marilyn would be delighted, as she reminds me from time to time that it would be good to have the space back, in the corner where she keeps all her garden tools. One last word of cautionary advise if you will. Please be careful when getting frustrated with your pump. Don't operate it rapidly such that you lose your grip on the handle, for if you do you run the risk of getting a flush wound. Glyn, H: 310.453.1892, C: 310.804.9198

Oh I have a few "flush wounds". :boohoo:

Yeah, I thought about the possibility of some how getting the installation backwards, but that's pretty much impossible because Jabsco parts all only have one way they can fit. If it turns out that my head is toast, I may consider your offer to sell your Groco. In all honesty I have not had too many problems with the head over the past 12 years. The macerator is another story though. Put a new one in last year and it's working fine for the moment.

I have my mechanic coming down to try and free the locking nut for my stuffing box anyway, so he's going to get to the "bottom" of my head situation as well. :headb:

Jeff,

Although by now you might have it solved, I'm wondering if there's a way you might have installed the valve piece backwards or upside down--that's the small rubber piece that fits inside the square plastic housing by the handle--those metal valves that are held in the rubber part need to open and close in a certain way, so if you have installed it wrong, your toilet won't work. Just a thought...

By the way, we have had our Jabsco toilet for 7 years and it has been flawless--simple, reliable technology, parts readily available if needed, easy to clean, inexpensive to buy. I know I'm in the minority, with others complaining about them, but I'm very pleased with ours!

Mine works like a champ. I'm a fresh water flusher though, and there is zero smell or problem. They can be rebuild stone drunk with a coat hanger in a hurricane.
That's the way I do it anyways..:)
