Howdy! Thank you for your inquiry about our Peerless RP70538 valve cartridge. According to Peerless, they don't have a rebuild kit for this cartridge. If you are experiencing a leak, they recommend replacing the RP70538 valve cartridge and the RP73625 check valve. We hope this helps. If you want to purchase a product, feel free to go to its product page, click "Add to Cart", enter your zip code and you're all set. Thank you for visiting PlumbersStock.com. Have a fantastic day!
