Toilet wont hold water.

[donr]

I have 2 Thetford elecric toilets on my boat.
Both fill and flush OK but neither will hold water in the bowl it just leaks out.
I have tried a couple of bottles of seal conditioner with no resuts, since it leaks out also.
I thought about removing the discharge hose and plugging it up to hold the seal conditioner until it has more effect but I,m hesitant to try that.
Parts no longer seem to be available either.

Thanks Don

Here are some tips from RV users of the same toilet?
