May I order a part for a Delta 522-MPU faucet?
The part for the Delta 522-MPU faucet that I need is the RP50 Cap with adjusting ring. Note on your diagram that this part has flats for removal by a hex wrench. In my home, one of my 522 faucets seems to have been made with an older style part which has knurling instead of the hex flats. It was nearly impossible to remove so that I could get access to the seals to replace them. I don't want to repeat the experience and would like to replace this part with your updated RP50 with the hex flats. Is this part available?
Thank you for your question! The RP50 cap can be replaced with the RP1050. Also, if the cap seems stuck, we recommend to try wrapping it with a cloth soaked in 50/50 white vinegar and water for about 15 minutes.
