HOW TO VIDEO
If Water is leaking around the base of your kitchen faucet it is normally caused by worn out O-rings. Replacing your o-rings is simple and can be done yourself. TIP: O-rings should be replaced every 10 years to keep your faucet in tip top shape.
To get started you will need a crescent wrench or strap wrench, small cloth rag (optional), flat-head screwdriver or needle-nose pliers and Silicone grease
Turn off the water supply to both the hot and cold sides of the faucet underneath the sink. Loosen the coupling nut from the base of the spout by using a crescent wrench (Tip: cover the crescent wrench with a rag to prevent scratching the finish) or a strap wrench to turn the nut counterclockwise. Note: If the faucet is a single lever type, you will need to remove the faucet handle before beginning.)
Once the coupling nut is loosened, twist the coupling nut counter clock wise to remove.
To remove the spout you will need to twisting back and forth then pull the spout up and off the base.
The O-rings should be easy to see and locate, there are at least one or two O-rings, but there could even be three or four, remove each o-ring using a flat-head screwdriver or needle-nose pliers.
Slip the new O-rings onto the faucet body within their grooved slots, making sure the O-rings are not twisted.
Reinstall the spout, handle and screws along with the plastic decorative covers in the reverse order to which you removed them. Turn water supply back on and test for leaks.
