Hello, I searched for many hours to try and find solutions and or a place to possibly get parts for a single handle shower faucet made by LDR. It has been dripping/leaking ever since the water pressure was low due to a break in the water line this spring. I disassembled the cartridge and looked for any faulty o rings or cracks in plastic, but did not find anything wrong. Any suggestions would be appreciated. I may just have to try a new cartridge assembly. Thanks for your time.
