Hey Bob, since the Thetford model 42050 is the Aqua-Magic II RV toilet yes the replacement water valve part # TH78SA that you referenced is correct part.

No, this part does not fit the 42050 toilet. Need to screen these answers before they get published. I purchased this part based on this expert reply and it does not fit.
