KBRP101C Pressure Balanced Washerless Cartridge (1 Piece), Raw

I purchased this cartridge to replace one that was leaking. It took a little bit of strength but I was able to push this new cartridge in its place and assemble the faucet back together with a new bonnet nut also purchased from this site. Everything worked like a charm! I'm so happy I got my bathroom sink back.

Simple to replace and working fine on our Kingston Brass faucet.

Cartridge and the washers I ordered with it are great! The order came quickly and was in a good box.

This replacement cartridge works. I just wonder why the original only lasted 2 years, by far the shortest life I've had from any faucet. I bought a couple extra cartridges, since I figure I will be needing them.

It is the wrong size for the tap .a little too big. May i return it and may you help me find the right one? If so, please send instructions on how to return it for a refund. Thank you.
