I have a Thetford 42070 RV toilet. Some google searches show this model as a fit for the valve. However, it is not listed on your parts page as a compatible part for my model.

Hey there Ryan! Thanks for the picture. It helps a lot.
Yes, you are spot on. The Replacement Water Valve for Thetford Aqua-Magic Style II RV Toilet - Restores Flush Power # TH78SA is a confirmed fit for the 42070 Aqua-Magic Style II that you have.
I will update the product page to reflect this fitment since it doesn't make it clear that it's a confirmed fit.
Let me know if you need anything else Ryan! Out of curiosity, do you have any fun trips planned, or are you winding down for winter months coming up?
