I have a house that was buildt in 1980 and all the plumbing water supply is copper.
In my Guest bathroom the handles for both Hot & Cold water haven't been working lately, they are slowly stripping the copper handle extensions, see photo attachments.
I bought several boxes of those universal handle adapters at Lowe's to secure to the copper handle extension. They secure with 3 very tiny screws, and lately these screws losen up or start to slip their grip and the other end screws onto the plastic knob.
Without getting into having a plumber come out a re-install new hot & cold lines into the shower with new updated hardware... is there a better way to save this situation?
I've attached 3 photos to make it easier to understand the situation.
Thanks for any help,
Scott
