Hello to all,

I have a three-stem shower set-up. When I use the diverter to direct water to the showerhead, I notice that water is leaking from the cold water stem (leaking through the escutcheon and traveling down the stem). Is there a washer or seat that needs to be replaced, or do I need to replace the whole stem. I have already replaced the diverter stem thinking that that might be causing the leak, but I still have the leak.

Thanks for all help in advance.
