MikeAqua:
Is it stuck open or closed?
If open Draino (powder/crystals not liquid) will deal to hair, fatty deposits and general goop. Read the label.
I don't see the benefits of these fittings. In my experience they cause more problems than they solve.
Closed, but the lid is unscrewed and is now open. Ill add that to the box of tricks. I feel we are hard water here from other symptoms, but it all helps
