OK, apparently this cartridge is not as popular as the 1255, as it was nowhere to be found at big- or small-box HW stores in San Diego. Nonetheless, Amazon came through in less than a day. The Moen product comes with an instruction sheet in the box, which has the necessary tricks to get the thing changed out. A 3/32” Allen wrench, small, is crucial to get the handle set screw loose. Also, the little red o-ring (Mickey Mouse shape) may remain in the faucet body, so a small seal pick, such as the OTC Tools 7312 https://www.amazon.com/dp/B000P70QPW is a handy way to extract the seal, if needed. The whole thing is a really quick fix with the 4000 cartridge. And no drips now. Yay! Read more

My faucet started to leak right at the handle. It was slow over time but recently you could tell it was ready to call it quits. It's super easy to access with some allen wrenches, pops right in and you are back in business. Read more

I like to leave reviews but some things, honestly it is hard to figure out what to say. This cartridge fit in my faucet easily, quickly and seemed to be a great replacement for what was in there. That is what I needed and what I got, so all needs satisfied. What I will add is that I ordered this very late in the day, I believe late Tuesday night, and yet it still arrived 2 days later on Thursday. I was expecting it to arrive on Friday. So, I thought that was a nice and unexpected bonus. Read more

Yes, it is easy to install. It doesn't flow very well, just like the original one. It leaked, just like the original one! That isn't the fault of this piece, it is the fault of the faucet. I think Moen is French for "wet, frustrated plumber". I had previously sworn I would never buy a Moen faucet again, that still stands! This faucet was installed when I bought the house, not I do not have a Moen faucet anywhere here (all Delta or Peerless now! Read more

Good instructions and perfect fit. 15 minutes for a faucet to work like new for around $10. The most difficult part was making sure I found the correct cartridge before ordering. Read more
