I bought this toilet about three years ago when I rehab'd the master bath. I think it was a Cadet 3 model, the model ended in 3 and it is a 1.6 gpf. Works great but, once when it was new, the flush valve leaked. I fixed it then but lately it is doing it again. The flush valve is not a typical flapper valve, it looks like a short plastic baseball bat, blunt end down with a thin silicone seal that looks like a miniskirt a couple of inches from the bottom. The seal keeps coming out of the groove it mounts in.
I have not seen this design in the new Cadet 3 or any other American Standard toilets and cannot find parts. I wonder if there is a conversion kit to the current flapper style flush valve. Is there a recall on this toilet? Do you think superglue might keep the seal in place?
