Are faucet cartridges interchangeable?
Also to know is, how do I identify my faucet cartridge?
For sink faucets, look at the front of the spout. The logo may also be on the base of the spout, where it meets the sink, either on the front or the back. For shower faucets, look on the round plate (escutcheon) behind the handle, on the handle itself, or perhaps on the actual valve behind the wall.
Similarly one may ask, are shower cartridges universal?
Cartridges aren't interchangeable among different faucets, so if you decide you need a replacement, you need to know its part number so you can order it from your plumbing supplier or online. That number is usually available on the manufacturer's website in the online version of the owner's manual for your faucet.
There is absolutely NO difference between the Moen 1222 vs 1222B replacement cartridges. They are both the replacement part cartridge for the Posi Temp Moen shower valve. They are made from the same parts, the only difference is their packaging and model number.
