Toilet flush valve stuck

While de-winterizing my 2015 38RL today I discovered the toilet would not open the valve from the bowl to the black tank. There had been antifreeze in the bowl for a few months and I think it might have attacked the seals. Any ideas as how to unstick this? If the seal is shot, can I replace it?

I've put rv antifreeze in every unit I've owned, while winterizing, with no ill effects. There needs to be something there to keep the seals from drying out, and water isn't an option during the winter.

Thanks. Does anyone know where I can get a diagram of the toilet innards?

It's a Thetford. Should be able to get it from the website.

Not sure if your toilet is the same as in my 2012 36RL, but here is the manual for mine. It might help.

Mine stuck briefly and I used RV antifreeze as well. I try to make sure that there is always some form of liquid in the bowl to prevent the gasket from drying up. Once I was able to open the valve I just kept opening and closing several times and it seems to be fine now.

I put a glove on turn off the water, open the valve, and apply Vaseline to the seal once or twice a month depending on use.

You might try some type of Teflon spray around the knife seals to get the valve going smoothly. Not sure.

More toilet help!

I can manually open the waste valve now and have lubed the seal. The foot pedal still doesn't move it, but it looks easy to fix if I can get the foot pedal off. Has anyone ever done that?
