    Worked Perfectly
    I am a landlord with multiple properties. It makes my life much easier when repairs can be done quickly and effectively. This part was easy to replace. I wish it hadn’t stopped working in the first place, but that’s the way it goes!

      Six years and still going
      We moved into our home six years ago, and this cartridge was in the faucet the previous owner had installed. It recently started to leak, and using the Delta website, I disassembled the faucet, removed the cartridge, cleaned it, reassembled it and now have a leak-proof faucet once again!

        How to fix leaky cartridge
        We have a 3 year old Delta faucet that started leaking. When I disassembled the cartridge, I found that the cheap white plastic sleeve or mounting disc that separates the black articulating ball from the white ceramic disc had broken apart. See attached photo. I attempted to glue this disc, so it looks less broken. However you can see that the half circle part that protrudes breaks down. In my case, it had almost completely separated or ripped off of the main white disc surface. This wear is from the protrusion from the black plastic ball wearing against this surface even though it is heavily lubricated from the factory. Because of this issue, this made it difficult to completely close off the water to the faucet. I disassembled the entire cartridge, cleaned all the parts, and reassembled without the plastic sleeve. I added some lithium grease lubricant to the ball assembly. The faucet now works and water shuts off completely without dripping. However, without the the plastic sleeve there is a little extra "slack" that you can feel when articulating the handle. The plastic sleeve acted to reduce or eliminate this slack, but when it breaks down, it interrupts with the proper movement of the ceramic discs. So, the faucet can operate without the disc, but you do have a bit of slack until the black ball engages the half circle slot in the white ceramic disc. While not 100% ideal, this is a good enough fix for an average product. I think if Delta manufactured this plastic disc out of a stronger material, they would eliminate the problem.

          Another one started dripping
          The quality of these cartridges is terrible. I replaced one 2 years ago and 2 more in the last year. Usage is on a regular house.... I will try this time with a non genuine alternative as paying the higher price for the original doesn't bring any advantage.

            Faucet leaks, runs randomly.
            2 1/2 years old. This faucet began leaking after only a year, then failed completely. I took the valve apart and determined the thin white plastic retainer, which holds the base of the lever in place, cracked. The bottom of the lever slips slightly out of the base and the sliding valve is unable to close completely, allowing the water to run.

              Stick with Delta's brand. Our Leland Faucet was 10 years old and it wouldn't shut off the water easily or it'd leak sometimes. I replaced this by prying off the little cover on the handle, using an allen key to take the handle off, unscrew the dome shaped part under the handle, then used a wrench to loosen the nut holding this cartridge down. Attached are the pictures of the old one. It looked pretty good but the internal parts must've moved or something. Instructions said no internal parts are repairable so it's a good thing I got a new cartridge. Popped it in, put the nut back on it, and reinstall everything. Took me under 6 minutes. Delta does offer a lifetime warranty on this part so contact them if you can wait

              Great Fix....so far
              Faucet leaked. So grateful that the whole system didn't require replacement.
