I have a Single turn knob for my shower made
By Price Pfister. The valve needs replacing.
Removing the knob and un-screwing the metal
Circular cylinder, I’m left with the stem valve.
From the front, It is circular with two tabs, one
On top and bottom. With a screw driver from the
Back tabs, and pulling on the handle, it will move
But will not pull out. How do I pull it out?

Sorry Leanord,

We can't do much without a model number. Regards, Tom

Will have to look for the mod# but the valve or cartridge that pulls
On and pushes off is made of plastic.
