Pressure Balance Washerless Shower Cartridge for Gerber GA507978

chat iconWHAT OUR CUSTOMERS SAY…

“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. ”

“Recently I purchased a rebuild kit for my American Standard R series bathtub faucet. I want to say thank you for carrying this product. The rebuild kit worked beautifully and I was able to save the original look and feel of our 1957 bathroom. Thank you! ”
