r/HomeImprovement on Reddit: Is there an easy way to tell what shower cartridge you need by just looking at the end that sticks out the wall?
December 9, 2022 -
Maybe I am just talking out my ass but why must they make it so difficult to identify by making you to turn off the main water and removing the part to find the number or taking it to Home Depot to match when they can just simply put a model number on the stem end for anyone to see??? It would be so much easier to order the part or at least check inventory status for the closest supply store before having to remove the whole cartridge.

Mine is moen brand (it’s marked on the shower handle). Google took me to a page on their website that shows they have 3 different styles and how to tell them apart. For moen, you could tell by the location of the screw holes. I’m not sure if other brands are similar.

December 9, 2022shower cartridge replacement
As a plumber the cartridge jobs are pretty annoying because we have to source out the exact part and come back, usually involves a couple visits. If its a Moen cartridge then yah the price is high. I've charged $500 to replace a higher end shower cartridge. Source out the cartridge yourself and have them just install it for a lesser fee. But this price seems par for the course to me.

June 2, 2022How do I find the right shower cartridge replacement?
It looks like 2112 is a Moen single handle shower system that uses the Moen Posi-Temp valve. I replaced some Posi-Temp valves in my showers, and it was pretty easy. The newer ones are brass and plastic, and seem to be working just as well as all the old all- brass ones. https://www.lowes.com/pd/Moen-1-Handle-Brass-and-Plastic-Faucet-Tub-Shower-Cartridge/3133585 ? They usually come with a crappy plastic faucet puller, but I spent the $16 on a metal tool to get the old cartridge out and put the new one in. It helped out a lot!! The old ones can be tough to wiggle out, and this was the right tool for the job: https://www.lowes.com/pd/Danco-Cartridge-Puller-For-Moen/1085199 More on reddit.com
