Easy even for an amateur!

I have ZERO plumbing skills, other than replacing some inner parts of a toilet tank, so when i researched that the drip in the faucet was from this part that needed to be replaced, i was skeptical i could do it, but other reviews said it was easy. Sure enough, very easy to do, the faucet works like NEW now, no drip! Go for it!

Original lasted 14 years

We love our Allora kitchen faucet and the Delta lifetime warranty that comes with it. The faucet started dripping until you played with the handle a bit so called support and, within 5 minutes, the cartridge and retaining nut replacement order was placed under warranty. I flushed the lines as instructed and performed the replacement... like brand new again! I hope the replacement lasts as long as the original.

Good, but a redesign could make it great

The original cartridge in my 2017 Leland kitchen faucet only lasted 2yrs before the drips started. The second cartridge lasted another 7yrs before failing the same way. Both times it took only a few minutes on the phone and Delta sent a free replacement. Kudos to them for standing by their product. I am a bit surprised that Delta did not come up with an improvement on the RP50587, but maybe they have moved away from this cartridge on new faucets. Seven years is good, but I have seen other similar design (ceramic valve) faucets last over 20yrs without leaking. This design uses two polished ceramic plates that slide against each other. The plates are forced against each other by the plastic case and partly by the faucet bonnet nut. When the holes in the plates line up, the water flows. When the movable plate slides far enough the holes no longer line up the water stops. On this failed cartridge there is no obvious reason for failure - the plate faces are still highly polished with no obvious scoring or wear on other moving parts - so why is it leaking? It is possible the plates while still polished, are no longer flat and do not mate well when moved around. There could also be tiny wear in the actuating parts that together prevent the moving plate from sliding as far closed as before. The forces that push the plates together may have lessened over time due to aging of the plastic/rubber pieces. Does Delta know what the failure mode is?

Hi valued customer, We appreciate you taking the time to leave your review! I am glad you are satisfied with the Delta Faucet model RP50587. A common cause for a leak with this cartridge can be wear or damage to the seal on the bottom. Thank you for your feedback and for being a loyal Delta Faucet customer! Best Regards, Bryan
