The dump valve for our Thetford toilet isn't fully closing, but I'm wondering it this is even an issue. Can't I just fill the drain pipe with water and then fill and charge the toilet? What is the benefit of the seal at the bottom of the toilet?

Speaking of toilets, I have been considering a switch to the Sealand 711-M28C, but don't really want to make the large investment. Would it be possible to modify a Thetford curve or similar cassette toilet by cutting a hole in the bottom and just draining the holding tank through the hole in the floor? How would this be much different than the Sealand?
