K31080 Insert and Seal with Tool

Easy to install, with good instructions

The photo shows the insert and seal, bit not the tool, which is a fitted punch. A bit scary to pound the punch hard with a metal hammer, but the press-fit old insert came out fine, and the new one likewise. I now see why the instructions for the removal of the old (non-threaded) insert emphasize the requirement for the tool (a type of drift). Don't try to remove it without the tool if you have not seen how it works. Grit had plugged some of the 8 holes in the faucet, and now I have more flow than ever!

Excellent

Thank you very much. My dishmaster works great.
