We built a house in 1976 and put in a shower with a Moen single knob hot/cold control valve. The escutcheon has Moentrol stamped on it.
Taking off the escutcheon plate the valve appears to be fully symmetrical left to right with a large slotted face (balancing spool?) located right above the knob axis on the vertical centerline.
The unit works OK but it's getting pretty hard to push/pull the knob. I see that later models use Model 1200 and 1225 cartridges. I haven't tried to take it apart. Assuming this thing has a cartridge, which model cartridge would it be?
Any advice appreciated.
