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

Re: toilet wont hold water.
Forget the liquid fixes for just about anything. There's only one solution; rebuild it. EBay is your freind. Search ebay for Thetford. Many seal kits show up. You will have to figure out which model you have so you can select the correct kit.
Rebuilding heads is easy. I just did my Crown.

Re: toilet wont hold water.
As Fred said - those seal additives are a joke. Bet you can buy the seal kit for less than what you have paid on additives.
