Replacing the Joker Valve on a a B321

Ron20324 · Sep 6, 2015

On my B323 I can remove and re-install the joker housing with the hose attached. YMMV.

IF..... there is room for a short connecting hose and then just enough space to make a turn, you might try a 90 degree piece of ss tubing. These are quite smooth, and you will need to rough up the exterior with some 60 grit to better clamp the hose onto. Use double clamps, but for waste you do that anyway.

I found a couple of these at McMaster Carr when I was re-formatting our whole head and holding tank scheme. I had some routing places where a tight hose radius would have kinked otherwise.
Of course, in most boats, there's hardly room for the head and the hose emerges from a bulkhead or cabinet with little clearance....

Anyhow, an idea, FWIW.

'all have done an amazing job of figuring out the hard way and the wrong way to s

Chris, the right solutions to your problem are 1. Don't remove the hose from the fitting, remove the fitting from the pump. 2. Swap the straight discharge fitting for a 90. You can get one from Jabsco (or whoever made your toilet) and aim it where it needs to go. Meanwhile, don't cut any more off..the outer diameters of fittings are sized to create a snug hose fit...sanding some off will result in a leaking hose connection.

Warming hose a bit makes it a lot easier to get off a fitting...warming it plus lubricating both the inside of the hose and the outside of the fitting with dishwashing liquid makes it a lot easier to put it on a fitting.

Loren, metal fittings should never been used in a sanitation system...you'd be smart to replace 'em with PVC 90s or 45s before you find out why (urine will eat through them, creating stinky leaks in your plumbing Check the plumbing department of any hardware store...if they don't have what you need, you can get 'em from Dometic/SeaLand... Here's a sheet from a Sealand distributor site http://www.marinesan.com/PVC-Fittings-s/120.htm or you can order direct from SeaLand 800-321-9886

The flange on the joker valve is the gasket that seals the fitting connection to the pump. You want to tighten the screws/bolts enough to get a good seal, but be careful not to OVERtighten them...that will cause the rubber flange/gasket to pucker at each of the screws...and leak. So just go for snug...if it leaks, no more than 1/4 turn of each screw (all of them) at a time till it doesn't leak.

And when you change the joker valve, DO NOT use original Jabsco three blade valves. I had four of them and they all leaked from the beginning. Buy some two blade copies and check that you can not see light through the lips.

Vaseline isn't a good idea for two reasons...it's petroleum based, which is damaging to rubber, and it stays greasy...hose can work its way off the fitting. The industry has always recommended dish soap, but K-Y jelly is even better because it's much slicker and it's water soluble, so it dries out...plus, it's cheap and available at any drug store and most super markets.

I would have used dish washing liquid if I had on the boat.

Preparation is the most important step in any project. It's when prep is "short changed" that people jury rig, substitute materials, charge ahead HOPING they can do it instead of asking questions etc... proving more often than not that it's always cheaper and easier to do it right the first time than it is to do it over.

So PLAN your projects...make a list of what's needed and get everything on it...if it's a job you've never done before, read the directions! If the directions leave any questions in your mind, ASK...post to a forum, contact tech support for that product--BEFORE you start. You'll be glad you did.

Can you post a link of a two blade copy?

Peggie Hall HeadMistress · Sep 7, 2015

"Two blade" is just his term for a joker valves that has a single slit instead of a Y or X cut into it...the most common type.

Btw, the slit should be aligned vertically.

Replace the joker valve on our 321 a couple of times ,found it easier to remove the hold down bolts that hold head in place then uncured joker valve housing replace valve,bolt up and blot head back in place (first pump some vinegar through system)
total time about 20 minutes

I agree with Peggie about metal potentially being a problem in the waste plumbing. Years ago when I reformatted our system, I could not find a sweep elbow like her current example. OTOH, our new HT has no bottom connections and we always pump enough water thru the lines when finishing the flushing process that all waste should be gone from the hoses and joints. Hope so, anyway.

I wasn't born knowing this stuff...I had to learn it too. And I'm still learning, even after 25 years.

Where can you find a two bladed joker valve vs the three blade that is specified by Jabsco?

Google will turn up a whole bunch of sources for it. This is what you're looking for...also in black.

Try Raritan, same size, two blade.

That photo IS a Raritan joker valve, Stu!
