Replacing a double bowl stainless steel kitchen sink with a single bowl undermount model involves several steps. Here's a general guide to help you with the process:
Gather the necessary tools and materials: You will need a utility knife, adjustable wrench, screwdriver, plumber's putty or silicone sealant, a bucket or towels, and the new single bowl undermount sink.
Turn off the water supply: Locate the shutoff valves beneath the sink and turn them clockwise to shut off the water supply.
Disconnect the plumbing connections: Use an adjustable wrench to disconnect the supply lines from the faucet and the drain lines from the sink trap. Place a bucket or towels under the trap to catch any water that may spill.
Remove the old sink: Loosen the mounting clips or brackets that hold the sink in place. They are usually located underneath the sink and attached to the countertop. Once they are loose, carefully lift the sink out of the countertop opening.
Clean the countertop: Thoroughly clean the area where the old sink was installed, removing any debris or old caulk.
Measure and mark the new sink position: Place the new single bowl undermount sink upside down on the countertop and position it where you want it to be installed. Use a pencil to trace the outline of the sink onto the countertop.
Cut the countertop opening: Use a utility knife to carefully cut along the traced line to create the opening for the new sink. Be sure to follow the manufacturer's instructions regarding the size and shape of the opening.
Install the sink clips or brackets: Most undermount sinks come with clips or brackets that help secure them to the underside of the countertop. Follow the manufacturer's instructions to install these clips or brackets.
Apply sealant: Apply a thin bead of plumber's putty or silicone sealant around the edge of the sink opening on the countertop. This will create a watertight seal between the sink and the countertop.
Attach the sink to the countertop: Carefully lower the new sink into the countertop opening, making sure it fits securely. Use the mounting clips or brackets to secure the sink to the underside of the countertop. Follow the manufacturer's instructions for the specific installation method.
Reconnect the plumbing: Reconnect the supply lines to the faucet and the drain lines to the sink trap. Ensure that all connections are tightened securely.
Turn on the water supply: Turn the shutoff valves counterclockwise to restore the water supply to the sink. Check for any leaks and make sure the water is flowing correctly.
Clean up and test: Wipe away any excess sealant or putty from the sink and countertop. Test the sink by running water and checking for leaks.
It's important to note that these steps are a general guideline, and the specific instructions may vary depending on the manufacturer and model of the sink you are installing. Always refer to the manufacturer's instructions for the most accurate and detailed installation process. If you're unsure about any step or lack the necessary skills, it's recommended to consult a professional plumber or contractor for assistance.
