When a sink is installed it is meant to last a lifetime, but a dropped skillet or other heavy object can chip the glazing or even crack the porcelain, requiring you to replace your old porcelain sink.Even if all that's wrong is that you're tired of the old color and style and are looking for something new, you'll want to get the old sink out of the way to make room for the replacement. Whatever your reasoning, there are a few things to keep in mind to make the sink removal as simple as possible.
1 Turn off the water supply to the home and then disconnect all of the water lines and drain pipes connected to the underside of the sink. Use the screwdrivers, wrenches and pliers to loosen clamps and uncrew nuts and bolts. Also remove the visible hardware (such as handles, faucets or spigots and other hardware) using a screwdriver, wrench or pliers depending on how they are attached to the sink.
2 Turn the breaker off to the garbage disposal if your sink has one and disconnect all of the wiring. Remove the screws mounting the disposal to the bottom of the sink and disconnect the disposal.
3 Look for any attachment clips or mounting brackets located on the underside of the countertop. Top-mount sinks may not have any, but undermount sinks are always mounted to the underside of the countertop. Loosen and remove these brackets with pliers, a wrench or screwdriver depending on what is required. Have a friend help you lower and remove the undermount sink.
4 Look for the seal around the edge of the porcelain sink for top-mount sinks. Cut the caulking around this edge with the utility knife to free the sink from the top of the countertop. Push upwards on the sink from below and have a helper pull it from above to remove it from the hole.
Items you will need
- Wrench set
- Utility knife
- For undermount sinks, be sure to work with a second individual to help you maneuver the sink out of the way as you are loosening the fastening brackets. If you are by yourself, brace the sink up with something, such as scrap pieces of wood, until you can lower it safely and slowly. To determine how your sink hardware is attached, inspect it visually. There may be a cap in place on top of the hot/cold water outlets keeping the bolt or screw from view. Simply remove the cap to access the screw/bolt.
- Do not attempt to remove a sink until you have turned off the water supply and the power to any electrical wiring that may be attached to your sink.
