Why does my Posi-Temp shower, with waterdrop knob, only give me hot water or cold water and not a mixture?
In most cases, the knob has been installed upside down. To correct this simply:
- Remove handle cap and the Phillips screw under the cap.
- Pull the handle off the faucet.
- Now replace the handle, only this time, make sure the point of the waterdrop handle is pointing downward to the six o'clock position.
- Replace the Phillips head screw and handle cap.
