Thank you for your question. Here are the instructions for installing a new set of seats and springs in your faucet:
First shut off the water supply to the faucet. Next remove the faucet handles.
A Phillips head screw located below the plastic cap on top of the handle holds on knob handles. Pry off the plastic cap with a butter knife or a small screwdriver to gain access to the Phillips head screw.
For lever handles, you should find either an exposed Phillips head screw on the top of the handle or, on newer faucets, a set screw on the side of the handle below the lever. The set screw can be loosened with a 3/32" Allen wrench.
Unscrew the bonnet nut. You will then be able to pull the stem unit assembly out of the valve body. The seat and spring will also just lift out of the valve body.
You may also need to flush out the valve body. Place a pitcher or bucket upside down over the open valve and turn the water back on full strength for 5 to 10 seconds. Do this on both the hot and cold sides. After the allotted time, turn the water off.
The wide part of the new spring goes down into the hole first. The larger opened side of the new seat then fits down over the narrow part of the spring and also goes down into the hole. Reinstall the stem units, bonnet nuts and handles in the reverse order.
