3.4 Installation Steps
- Prepare the Vanity/Countertop: Ensure the surface where the sink will be placed is clean, dry, and level.
- Install Faucet (if applicable): Before placing the sink on the vanity, install the faucet and drain assembly according to their respective manufacturer's instructions. The sink features three mounting holes for an 8-inch widespread faucet configuration.
- Apply Sealant: Apply a continuous bead of plumber's putty or silicone sealant around the perimeter of the drain opening on the underside of the sink.
- Position the Sink: Carefully lower the vanity top sink onto the vanity cabinet or countertop. Align it properly and press down firmly to create a seal.
- Secure the Sink: If your vanity or countertop has mounting clips or brackets, secure the sink according to the vanity manufacturer's instructions.
- Connect Plumbing: Connect the hot and cold water supply lines to the faucet. Connect the drain assembly to the P-trap. Ensure all connections are hand-tightened, then use an adjustable wrench for a final quarter-turn, being careful not to overtighten.
- Test for Leaks: Turn on the main water supply slowly and check all connections for leaks. Run water through the faucet and into the drain to ensure proper drainage and no leaks.
