I had a damaged seat in the hot side of the tub faucet. I pulled the seat and noted it’s size and cannot find a replacement seat that matches. The seat is about 1-1/4″ long. Can I replace the seats with the standard short seats and then get a different cartridge set to mate up with the new seats? I guess my question is are the threaded pipes behind the wall standard to adapt any cartridge? I hope someone out there can help me. Thanks.
