I am replacing the diverter valve in a 1963 residential shower and wondering if anyone knows the make and model from the maker's marks on this hardware?

I see imprinted: P-P, C.W., and 18. The hardware appears to be cast iron and brass, with one nylon lock washer, and one rubber washer.

diverter valve stamped P-P

diverter valve stamped C.W. and 18

"P-P" is likely Price-Pfister. Since 2010, they have been known simply as Pfister.

  • Totally forgot about my question. You're correct. I took it to a most awesome specialty plumbing shop who knew it right away and found a replacement.
