I was given a Roman tub faucet buy someone who had it "sitting around" for years. They said all the parts were there. Ha. Should have known better! (To make matters worse, I went out and purchased the matching sink faucets, which my dear husband promptly installed.) He procrastinated on the tub.....so now I have to make this work.

Anyway. The rough valve is missing some parts. Ok. So I am trying to find out what rough valve I need to purchase to use with this particular set...I can't seem to find the same information anywhere.

The Roman Tub faucet is Price Pfister Treviso 806-DY11. I need to know if it will work with a rough valve 0X6-140R. How can I find this out? I hate to order it and then find out they won't work.

Thanks so much!
