Shower Diverter Problem

[dbruce45]

I've got a plastic diveter stem I can't stop from leaking. I replaced the O-ring but I'm not sure I've seated it properly because it continues to leak.

It may need replacing but I can't find one on-line. Unlike most diverters, this one slides into a 3/4" or 1" male line with threads on the inside for the brass nut that holds the stem in place.

Does anyone know where I could get a replacment or have any suggestions on how to stop the leak with what I have? Thanks.

Never seen one like that, but that doesn't say much! If you're lucky, the pros have.

It's maybe time to consider updating to a new anti-scald valve.
