To replace a kitchen sink, disconnect it from the drain pipes and supply lines, remove it from its position, and install a new sink in the place of the old one. Turn off the water supply to the sink before you start this project.
- Uninstall the old sink
Turn off the water supply to the sink, unscrew the slip nuts from the drain, and detach the sink from the dishwasher and disposal. Remove the mounting clips beneath the sink, cut any adhesive with a utility knife, break the seal, and lift the sink out of position.
- Install the new sink
Turn the new sink upside down on the floor, and then fix the faucet and supply lines. Use plumber's putty and Teflon tape to fix the strainer onto the new sink. Seal around the sink opening with silicone, and fit the sink into the position held by the old one. Fasten new mounting clips beneath the sink, and reattach the drain pipe, trap and supply lines.
- Test the new sink
Turn on the water supply to the sink, test the sink faucet, and fix any defects. Allow the silicone to dry, and scrape off the excess with a utility knife.
