In this article, we will provide you with a step-by-step guide on how to change an undermount sink and answer some frequently asked questions related to the process.
Step 1: Gather the Necessary Tools
Before you begin the project, make sure you have all the tools you will need. These may include a wrench, screwdriver, utility knife, silicone adhesive, plumber’s putty, and a bucket.
Step 2: Turn Off the Water Supply
Before starting any plumbing project, it is essential to turn off the water supply. Locate the shut-off valves under your sink and turn them clockwise to shut off the water flow. Don’t forget to run the faucet to ensure there is no water left in the pipes.
Step 3: Disconnect the Plumbing
Using a wrench or pliers, disconnect the water supply lines from the faucet. If there is a garbage disposal or dishwasher connection, disconnect those as well. Place a bucket under the pipes to catch any remaining water.
Step 4: Remove the Old Sink
Loosen the clips or brackets that hold the sink in place. Once they are detached, carefully lift the old sink out of the countertop. Be cautious not to damage the countertop during this process.
Step 5: Clean the Countertop
After removing the old sink, clean the countertop thoroughly. Remove any adhesive residue or silicone using a utility knife or scraper. Ensure the surface is smooth and dry before proceeding.
Step 6: Install the New Sink
Apply a bead of silicone adhesive along the rim of the sink cutout on the countertop. Carefully lower the new sink into place, ensuring it is centered and level. Press down firmly to ensure a secure bond between the sink and countertop.
Step 7: Connect the Plumbing
Reconnect the water supply lines and any other plumbing connections, making sure they are tight and secure. Turn on the water supply valves and check for leaks. If any leaks occur, tighten the connections further.
