Made an amatuer mistake with shower valve installation

mikec · Jan 11, 2009

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?

Most moentrol shower faucets have the handles facing up . (clockwise)Cold on the right, (counterclockwise)hot on the left.

AS may have the handle facing down, so it may look reversed, but it actually works in reverse. Arrow facing down, (counterclockwise)right hand is cold, (clockwise)left hand is hot

It's an AS valve and is installed correctly it is the fact that the pipes themselves are backwards.

Call American Standard and see if they make a cartridge that reverses the hot/cold. Several manufacturers do. If it turns out that they don't, you could maybe switch the lines somewhere where it is more convenient, like in the crawl space or the ceiling below.

Ultimately, they were the ones with 'backwards' piping.

Careful with that. Ten years later, I still tease my friend about the time he accidentally switched someone's toilet to hot.
