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!

Seller Verified Purchase
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!
