“These people were extremely helpful in taking me through replacing a 25 year old hard water frozen cartridge on my Philrich sink faucet. They were able to identify the correct part I needed from a photo I sent (I had it figured out wrong). I was pleasantly surprised they had an obscure part like this, but they also told me how to extract the old one when I couldn’t get it out. They said to unscrew it after I had concluded from YouTube the old cartridge was supposed to just slide out. It threaded out as they said and saved me buying a cartridge extractor and a hernia. The whole experience has been excellent. ”

The Peerless RP70538 is a single-function pressure balance valve cartridge used in many Peerless (and some Delta) single-handle tub and shower faucets. It helps control both water temperature and volume, and the pressure balance mechanism protects users from sudden temperature changes.
