I replaced the shower diverter and seat due the shower and tub running at the same time and I still have the same problem. I have taken out the diverter numerous times and don't see anything wrong with it. ANy help would be appreciated. Oh, it is a sasco valve with a separate hot, cold and diverter valve.

Hey Ollie,

I can not draw up a image of a Sasco tub valve. Does yours look like the one in the attachment? Tom

Yes that is it. Do I need to put teflon tape on the seat threads? Thanks

Good morning Ollie,

"Do I need to put teflon tape on the seat threads?"

Yes, treat the seat threads just like you would any threads that hold back water pressure.
