Step 1: Gather the Necessary Tools and Materials
Before starting the installation, make sure you have all the tools and materials required. This may include an adjustable wrench, pliers, Teflon tape, a screwdriver, and of course, the under sink carbon filter kit.
Step 2: Turn Off the Water Supply
Locate the shut-off valve under your sink and turn it clockwise to shut off the water supply. This is important to prevent any leakage or damage during the installation process.
Step 3: Disconnect the Existing Water Line
Using pliers or an adjustable wrench, carefully loosen and disconnect the existing water line connected to the cold water supply valve. This will allow you to install the carbon filter system in between.

Follow the instructions provided with your under sink carbon filter kit to install the filter system. This generally involves attaching the filter housing to the mounting bracket and connecting the inlet and outlet tubes.
Step 5: Connect the Water Lines
Attach the water line that was previously disconnected from the cold water supply valve to the inlet side of the filter system. Use Teflon tape to ensure a tight and leak-free connection. Then, connect the outlet tube from the filter system to the faucet or water dispenser.
Step 6: Test for Leaks
Once the connections are made, turn on the water supply and check for any leaks. Make sure all connections are secure and no water is escaping from the filter system or any other component.
Step 7: Flush the System
Before using the filtered water, it’s important to flush the system for a couple of minutes to remove any carbon fines or loose particles. This will ensure the cleanest and freshest water.
