We just bought a house that was built in 1971 and the master bathroom had a single handle Price Pfister Flow-matic shower valve that was corroded and falling off. We wanted to put on a new handle but none of the newer models fit. We called the home warranty company who sent out a plumber who basically said he had never seen anything like this type of piping in 15 years, and apart from cutting the three pipes in the wall and putting in a modern system, which he wasn't too keen to do as it would require a lot of back and forth with the warranty company, the only other thing to do would be to get a longer screw to put the old handle back in place. We are wondering if anyone has seen this type of valve and what would model handle would fit on. Thanks!
