Posi-Temp/Moentrol Last updated Save as PDF I haven't used my PosiTemp shower in my guest bath in a while. I now only get hot or cold but not both.The temperature on my Moentrol shower seems to be reversed. Cold water is where hot should be and the hot water is where the cold should be. Is there an easy way to change this?What is meant by "pressure-balancing" tub and shower faucet?What is the difference between a Posi-Temp tub and shower valve and a Moentrol shower valve?What size hex wrench is used to remove my Posi-Temp lever?When I first turn on my Posi-Temp shower, I get scalding hot water. As I turn the handle counter-clockwise, the water gets cooler. How can I fix this?Why does my Posi-Temp shower, with waterdrop knob, only give me hot water or cold water and not a mixture?
