jabsco electric head problems

[edbulmer]

We have a Jabsco electric head and it does not seem to flush properly, I put a new motor on it, cleaned out the joker value, but when you pee in it, the pee seems to just recycle itself and stay in the bowl even though water is going in and out of the unit. Anyone know if a solution to this problem.

May be a stupid question, but you sure the water isn't pee colored? Food coloring would tell for sure

[edbulmer]

no we have tried colored water, it just recycles in the bowl.

Did you put the joker valve in facing the right direction?

[edbulmer]

yes, it can only go one way

When you say you put a new motor on it, did that include a pump set?

It sounds like the seal between the raw water suction pump (the rubber impeller one) and the discharge pump (with the macerator) is faulty. It is only a small flat rubber washer. It wears on the shaft and leaks between the two pumps. This leakage prevents raw water being sucked up to flush the bowl and just recycles the bowl contents.

Jabsco makes several electric toilets, but assuming yours is the common 37010 series toilet, Craig is right. About the only way urine could recirculate is if the seal between the intake pump and discharge pump has failed. Following is a link to the owners manual for that toilet. If you scroll down to the parts list, the seal in question is number 19 on the drawing.

Bingo, you guys are awseome. Now where can I find one? Would I just goole Jabsco suppliers?

[HopCar]

Send me an email through my website, hopkins-carter.com, with your address and I ask my friend at Jabsco if she can just mail you one.

I'm clicking on your website on contact us but nothing is happening.
Also the intake and discharge unit on my toilet the 37100 series are one unit and this whole unit was replaced last year. Would it still be this washer?

It works for me. The site asked how I want to send the email, I chose gmail and it brought up my account and a new email with the address filled in. Using FF.

[edbulmer]

still can't get it to work. I will send you a pm.

This is occurring on one of our heads right now, but we know that the hose to the holding tank is mostly clogged with deposits and needs to be changed. It's on this week's todo list..... The fun just never seems to end.

Lets try this, hopcar marine at yahoo dot com. Take out the spaces and put in the little @ thing.

Ed I don't know the 37100. It's not in my catalog. Are you sure yours isn't a 37010?
The 37010 has one motor with a long shaft that drives a rubber impeller intake pump, a centrifugal discharge pump and a set of chopper blades. It's the seal between the discharge pump and the rubber impeller pump that we think might be your problem.

Capt. Bill brings up a good point. If there is back pressure caused by a clogged discharge line, it would try to push sewage past the seal in question. You should check that the discharge hose is clear all the way to the tank. Check the tank vent as well. That might be what caused the seal to fail.

I put on a new pump/motor that I was going to put in another head and still the same problem. So I now know it's not the seal. Could it be a blockage that would do this. I do see swirling and it looks like it's trying to flush but nothing seems to be going anywhere. Could I use a snake on it? I just bought a powered one.
