Toilet valve problem

[Charles Q Treichel]

I am fixing up and old 77. The problem I am having with the toilet is than the water will not shut off when the bowl automatically fills and therefore overflows. There does not appear to be any access to the valve that controls this. For this reason I have to temporarily turn off the water to the toilet after each use. Any tips on how this system works and how to fix it would be greatly appreciated.

If you go to the Thetford site: http://www.thetford.com/parts.cfm and select the model you have you ca n see a parts break down. When ours had problems I added up the bits an pieces and figured in the long run it was cheaper to replace theold one with a new one for $156.00 plus tax. YMMV
