Have one of those HD Glacier Bay Showers Their Model 8473100GB or 8474100GB
It's the kind that has a slider bar that provides for a hand held shower head (via a hose) and also a top mounted shower head
There is a 3 position valve at the bottom of the bar that selects one or the other, or both heads.
The valve handle has gotten loose, and is no longer firm in it's housing. If pushed in, and held, it works fine.
Can't find any replacement part drawing for what is likely nothing more than a screw that has become loose, somewhere.
Anyone familiar with these kinda things, and can perhaps suggest what might be wrong, and how to go about repairing it ?
Much thanks, Bob
