Outstanding Diverter

This unit is very well designed and it's manufactured with the highest quality materials. With a quick quarter turn in the lower valve, all the water goes to the shower head. The Moen Posi-Temp water valve is the best shower/bath water control I've used. I highly recommend this all in one unit.

Warm shower at best

I Purchased 2521 I cannot get a hot shower out of this system. I had a professional plumber install system. I turn the valve to hot setting and the best I can get is a warm shower. When I turn the shower knob to full hot and then turn hot water heater valve off at tank this valve continues to deliver cold water from shower head. Can I stop this valve from mixing cold water in with the hot water when it is on its maximum setting? My old valve would deliver only hot water thus producing a nice hot shower.
