Shut Off Water Supply and Prepare Workspace
With your tools gathered, shutting off the water supply lines under the sink is next so no leaking occurs mid-installation. Locate shut-off valves and turn them clockwise fully to cut off the water. Open the faucet to release pressure and ensure water is no longer flowing. Place a bucket under pipes to catch any excess water.
Clear out under your kitchen sink workspace entirely in advance as well so you can access the area easily. Have paper towels handy to place small parts removed and catch drips while installing your kitchen faucet. Assemble all new faucet parts like washers, nuts and fittings so they are within reach.
Remove Existing Kitchen Faucet
Now comes removing the existing kitchen fixture from your sink:
- Disconnect flexible supply lines from shut-off valves and faucet inlets. Unscrew lines using adjustable pliers or wrenches.
- Take out mounting nuts and retaining nuts holding old faucet from above. You may need a basin wrench to reach into tight spaces.
- Carefully lift up the faucet from above the sink and place aside. Take out any remaining sealant, washers or debris left over at the sink base.
Thoroughly clean your sink surface area with a non-abrasive cleaner. Ensure no debris or previous caulk is left so your new faucet can adhere properly. Rinse and dry completely. At this stage, take time inspecting tubes, supply lines and shut-off valves for cracks or leaks since fixing issues is easier before the install.
