Thetford Style II

I guess I have to chime in here and give my two cents worth. I have to say that the the Thetford Style II is really a great designed toilet. I have to agree that the mechanical parts could be made out of brass or metal but the design cannot be better for maintenance. I ordered all the parts on Amazon and it cost about $75. Two screws to pull the toilet out- 3 minutes. Placed a doubled up rug on the tailgate of my truck and laid the unit down on its side. Watched the Youtube video on removing and installing the pedal. Removed/replaced gate ball arm after greasing with plumbers grease, greased spring and replace water valve and vacuum breaker, installed new waste ball and screwed in the waste ball arm,replaced pedal. Paying attention to placement of spring into pedal = 45 minutes (Because I wasn't paying attention to that danged spring placement.) I could do all that now in less than 10 minutes. Set the toilet up and removed two screws from behind- turned the bowl counter -clockwise and removed porcelain upper. Removed/replaced the gate ball seal after applying plumbers silicon grease. Replaced the upper and screwed the two screws back in. Pay attention and make sure you use the plastic washers first against the porcelain and do not over- tighten. Replace closet bowl seal and reinstall the toilet. BAM - all in about an hour and most of you could probably do it in less that thirty minutes once you know how. So the Style II is made to be easily serviced and maintained. Of course I drained the Blank tank first and I cleaned the toilet prior to removal. I used latex gloves but man, this was really easy. I am thinking maybe you should rebuild maybe every 225 nights if you use the commode like one does in the sticks and bricks.
