Ceramic Stem Disc Faucet Cartridge Replacement for Bathroom Tap (1 Pair Hot & Cold),2103201

These cartridges fit a pair of lavatory faucets I bought more than 10 years ago. I have seen the faucets under several brand names but they are now discontinued. The description and model number was: WAS00x-07, 4 in. Centerset 2-Handle Bathroom Faucet in Satin Nickel with Drain. I’m not much of a plumber, so don’t know how cartridges are standardized for these types of faucets but I have tried several options that don’t fit and these ones do fit. It’s as simple as that.Installation is also simple. Turn off water to faucet. Remove handle top with screwdriver, remove top of fixture which secures cartridge with wrench, pull old cartridge up and out (observing orientation). Ensure seat where new cartridge will go is clean, then push cartridge into place using orientation tabs on cartridge as guide. Reinstall hardware in reverse order of removal. Turn water back on. Note: check for leaks at shutoff valve when closing and opening, sometimes these valves leak after being in one position for many years. A leak may stop when valve is turned back to where it has set.I’m very happy to have found cartridges that fit and would buy again.

Easy to install. Red for hot, blue for cold good seal.

Went to the big box capital h capital d store that I bought the faucet from and got ones that didn't work. the ones I bought on Amazon did work. Took 5 minutes to replace.

Worked

Worked exactly as expected, the color coding is useful. Arrived on time, and went in easy. Not much more to say. Thanks!
