Review on 🚰 Delta RP47422 Two Handle Ceramic Stem Cartridge Pair for Faucet by John Eaton

I just replaced cartridges for kitchen faucets that started dripping less than two years later. It seems a little less than a full life. They are relatively easy to install. The only difficulty is making sure the protrusions of the ruler are fully seated in the grooves. If they are not fully seated, the hood will not attach. This is a fairly simple setup; Remove the cap, pull out the cartridge, keep the gaps right, put the cap back on and put it back on. Hope it lasts longer than the original. In fact, it didn't last at all. One cartridge works great, no leaks. The other cartridge always leaves two drops. They're not readily available locally, so I may have to back-order. I can't return it because I can't without a cartridge and the rest were shot. This is not good advertising for Delta faucets which I have always had good luck with as I have had with Moen.
