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
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.
