Leaking Kohler Vinnata kitchen faucet.

To remove the plastic insert on your Kohler K-171 kitchen faucet, you can follow these steps:

First, turn off the water supply to the faucet.
Next, remove the handle of the faucet by unscrewing the set screw on the underside of the handle using a hex wrench or an Allen key.
Once the handle is removed, you should see a plastic insert that covers the cartridge. To remove this insert, use a flathead screwdriver to gently pry it off.
Once the plastic insert is removed, you should be able to access the cartridge.
If you need more detailed instructions, you can refer to the installation manual for your Kohler K-171 kitchen faucet .
