I have a Moentrol single handle shower control with diverter. I recently changed the Cartridge and Diverter. I also finally figured out why the hot was cold and cold was hot, simple adjustment.

The issue I have now, and always ave had, is in order to get hot enough water for a shower I have to have the knob on the 10 o'clock position as opposed to 12 o'clock.

Is there an adjustment for this or is it possibly a bad Balancing spol or Stop Check Valve?
