Made an amatuer mistake with shower valve installation
I installed a new American Standard R120 Ceramix shower valve on one of my jobs. I did not check and assumed the hot was on the left as it should be. I installed it as I always do and just received a phone call that the hot and cold are reversed. I simply soldered it in place where the existing was and of course that was a Moen with a reversible cartridge so no problem before my installation of this valve. I cannot reverse the installed cartridge in the AS so I am screwed unless someone knows of another cartridge that reverses the flow. Anyone?
