White, wax paper like residue in Moen cartridge
I have a strange thing happening. My tub faucet started leaking so I went to replace the cartridge as I have done a few times before. When I removed the Moen cartridge it had a bunch of pieces of little wax like paper stuck in different parts of the cartridge. I put in a new cartridge and it started leaking again a couple of days later. When I pulled out the new cartridge it also had this wax paper stuff clogging it up. Any ideas what this stuff is and how to get rid of it? Thanks.
