I have a Thetford Aqua Magic toilet in my Hurricane motorhome. It has developed a leak at the base of the flush nozzle assembly on the back of the toilet. I have attempted to remove the flush nozzle ...
Disconect water line and take the the two nuts loose and remove the toliet. You can now get to the flush vale and remove the two screws to remove flush valve. There is also a piece of tubing that goes to bowl. I had a leak in it as it is thin plastic. You can get parts on line, flush valve runs around $30. Not a hard job.
