I am replacing my bathtub faucet cartridge, which is made by Moen. I am not sure the original part number, but the Moen website has a handy lookup menu, which got me close... The cartridge is either part number
1200 or 1225. I can't narrow it down further than that without pulling out the old one.Does anyone know what the difference is between these two parts? Are they totally interchangeable? I just want to be sure when I purchase my new one, it's correct.
By the way, amazon.com actually has good prices on these!
Thanks!!
