Universal Joker or Sanimarin replacement

The "joker" valve on my Sanimarin electric toilet is a joke, it's just a flapper valve that almost always develops a slow leak and allows backflow into the toilet. Also, unlike other electric toilets the valve isn't incorporated into the toilet, it's just attached to the outflow pipe and then the other end is attached to the pipe that goes to the holding tank. I've tried 4 different types of flapper style valves, although some work longer than the Sanimarin version they all eventually start letting the toilet slowly refill with the sewage that was in the line to the holding tank (which is above the toilet so it has some head).
Ideally I'd like to switch to a real duckbill style joker valve like Raritan and Jabsco use. However they all require a housing which I wouldn't have. Does anyone know of a "universal" duckbill style joker valve that can just be connected inline to the outflow line (it's a 1.5" line)? Barring that, any better solution than a flapper valve? Thanks.

Re: Universal Joker or Sanimarin replacement

According to the"official manuals" for both electric Sanimarin toilets, I'm pretty sure you do have the fitting you need....the joker valve fits a 1.5" discharge fitting and your toilet has a 1.5" discharge fitting (appears to be an elbow) connected to the pump. A joker valve goes into that fitting...the flange on it becomes the gasket that seals the connection.

I've tried to find an exploded drawing for the Sanimarin, but one doesn't seem to exist on their website. If you have one and can email it to me (to do that, just click on my name at the left of this post and select the email option...there's no way to attach anything to a PM) I think I'll be able to show you where it goes.

Their manuals are positively awful!. It's been a while since I actually disassembled it, but if memory serves there's just basically a pvc pipe coming out of the toilet. While it is probably 1.5", the problem is where the "duck" part of the duck valve goes? Into the discharge flexible hose? I'd worry that it wouldn't operate properly there because it's bent a bit, and I would have thought the duckbill would need to be in a rigid housing? Sorry if these are dumb questions, just having a hard time visualizing it.

Re: Universal Joker or Sanimarin replacement

I agree 100% that what passes for Sanimarin owners manuals is awful! The only ones that are worse are Thetford's!



This is the owners manual for a Raritan SeaEra Raritan SeaEra owners manual I know the SeaEra isn't the same design as your Sanimarin, but it does have a detailed exploded drawing that shows where the joker valve goes--which is prob'ly not the same location on your toilet) and the fitting it goes into...That's on page 12. The drawing on page 7 under Discharge fittings may help you even more 'cuz it shows HOW it goes into the fitting. If that "PVC pipe coming out of your toilet" is bolted on to the pump body, you should be able to put the joker valve into it as shown in the drawings.
