How to remove a Kitchen Sink – 9 easy steps

Kitchen sinks are one of the most frequently used household fixtures. They are unquestionably necessary for a kitchen to function properly.

Kitchen sinks, on the other hand, can become outdated, stained, and even leak after years of use.

A new sink can address these issues while also updating the look and function of your kitchen, but first, you must determine how to remove the old one. Remove your old kitchen sink by following these simple steps.

Disconnecting the Sink is the first task.

Step 1: Determine the make and model of your sink.

Kitchen sinks are available in two basic styles: under-mounted sinks that are attached to the countertop from beneath, and drop-in sinks that simply drop into the sink opening in the countertop.

There are only minor distinctions in how each type of sink is removed, which will be explained as you progress through the steps.

Step 2: Open the cabinet beneath the sink.

Because this is where the majority of your work will be done, thoroughly clean this area.

It will provide you with additional space for the movement and storage of a bucket or tools.

Step 3: Protective eyewear and gloves should be worn at this point.

The area beneath the sink is compact and confined, with numerous pipes and other eye hazards.

Additionally, this job can be messy and taxing on the hands, so it’s a good idea to wear gloves. Bear in mind that while wearing personal protective equipment may seem inconvenient at times, it may ultimately prevent you from suffering pain and injury.

Step 4: If you have one, unplug it.

Due to the fact that electricity and water do not mix, it is critical to unplug your disposal immediately. You may also wish to disconnect the disposal from the circuit to which it was connected.

Turn off the circuit breaker that controls the garbage disposal plug at the fuse box in your home.

Step 5: Disconnect the sink’s water supply.

Two separate valves, one for hot water and one for cold water, should be installed beneath the sink. Occasionally, the hot water shutoff knob will be red and the cold water shutoff knob will be blue, but this is not always the case.

In either case, clockwise turn both handles completely off. By turning on the water in the sink, double-check that they are closed. While a few drips are acceptable at first, the water flow should be completely eliminated. [two]

If water continues to flow, you may need to consult a plumber to replace your shut-off valves, or you can replace them yourself using the steps below.

If there are no water shut-off valves beneath your sink, they must be located further down your water pipes. Follow the water supply lines as far as possible, looking for valves that could be used to shut off the water flow.

If all else fails, there should be the main water shutoff located either at the point of entry to your home or at the curb in a meter vault.

Step 6: Remove the water supply lines from the faucet’s underside.

Water supply lines that connect to kitchen sinks are typically made of flexible plastic tubing that is secured with metal nuts on both ends, at the sink and at the water shutoff valve.

Because the connection to the sink is located on the backside of the sink’s bottom, it can be a little difficult to access. To loosen the nut on the waterline, use an adjustable wrench, channel locks, or an open-ended wrench, whichever fits the space best.

With one hand, secure the line in place while loosening the nut with the other. This will allow you to maintain the line’s upright position if it becomes disconnected.

A small amount of water will remain in the line, so keep a bucket nearby to empty it. (four)

Spread towels across the bottom of the under-sink cabinet to collect small spills and cut down on clean-up time later.

If the connection between the water lines and the sink is completely inaccessible, you can typically disconnect the lines at the water shut-off valves.

Bear in mind, however, that you must be gentle with the connections on these valves, as breaking them would result in a flood of water into your kitchen.

Step 7: Unplug the sink’s drainpipe.

A slip nut or a coupling nut is used to connect the drain pipe to the bottom of the sink strainer. This nut connects plastic drain piping to a metal sink strainer.

With channel locks or an adjustable wrench, first, loosen the nut that secures the strainer to the drainpipe.

Typically, this is a plastic nut that can be loosened by hand, with some strength. Once this nut is dislodged, refrain from separating the connection!

Additionally, you must loosen the slip nut on the far side of the P-trap, which is a distinct J- or U-shaped span of pipe in the drain line beneath the sink.

By loosening this nut as well, you should be able to remove the entire section of piping between the strainer and the far side of the P-trap without damaging the piping. Keep your bucket close at hand to collect spills.

If your sink is mounted beneath the counter, additional drain piping may need to be removed to make room for the sink to come out.

Remove the drain pipe further past the P-trap, allowing for an angled sink. Whatever you remove is easily replaceable as long as at least an inch of pipe remains visible where it enters the under-sink area.

Although a slip nut connection is designed to be removed by hand, if you are unable to do so, you may want to wrap a rag around it and gently turn it with your channel locks to avoid damaging the slip nut.

Step 8: If you have one, disconnect the garbage disposal.

To begin, you must unplug your disposal’s drain pipe. With a screwdriver, unscrew the primary connection between the garbage disposal and drainpipe.

Additionally, if your dishwasher is connected to the drain via your garbage disposal, you may need to remove the dishwasher’s drain line.

This is a straightforward connection that should be simple to disassemble using a screwdriver or a wrench, depending on the fixture.

Step 9: If you have one, remove the garbage disposal.

Certain garbage disposals come equipped with a specialized Allen wrench that allows the assembly to be disconnected from the connection (this should come with your disposal when you buy it.

Turn the special wrench counterclockwise with one hand while maintaining control of the disposal with the other. Snap rings are used to connect other types of garbage disposal units to the bottom of the sink.

One ring is attached to the sink’s bottom and the other to the disposal using this connection.

The two rings are then sandwiched together by several screws that can be easily loosened and removed during disposal detachment. In either case, the unit will rapidly detach and you’ll need a firm grip on it to catch it.

Often, a sink with two bowls will have one bowl directly connected to the drain and the other directly connected to the garbage disposal. In this case, both connections must be severed.

Task 2: Removing Your Sink

1. Cut around the kitchen sink’s caulking.

Slice carefully through the sealant along the fixture’s edges with a utility knife. Avoid cutting into the countertop if you intend to keep it.

2. Remove the sink from its mounting bracket on the countertop.

If you have an under-mounted sink, you will need someone to hold it up while you detach it; otherwise, it could fall on you. This step is optional for top-mounted sinks.

Disconnect the sink’s metal clips from the countertop. Remove the tiny clips with a screwdriver. Because these screws may be difficult to access or rusty, take your time and be patient when removing them.

To enable your assistant to support an under-mounted sink, remove the strainer from the sink, allowing them to grasp the sink via the strainer hole.

A locknut located beneath the sink secures the strainer to the sink. To loosen the locknut, use large channel locks and turn it clockwise until it detaches. Then simply tap the strainer’s bottom to release it from the sink.

3. To loosen the sink, reach beneath it and gently push up on it.

If it does not easily move, work your way around the sink from side to side, pushing up until the fixture is loosened on all sides.

If you are having difficulty detaching the sink and are concerned that it will pull pieces of your laminate countertop off, have a helper cut along the caulking as you push up on one side of the sink.

This should enable you to remove the sink without accidentally removing some of the finish from your counter.

4. Remove the sink from the countertop.

While stainless steel drop-in units are light enough to remove on your own, older porcelain sinks can be quite heavy, so enlist assistance.

Taking out under-mounted sinks is a little more difficult. Angle it out of the cabinet doors, taking care not to damage any cabinet surfaces or remaining piping.

5. Clean up spills and surfaces.

With a paint scraper or a razor blade, scrape away any old caulk or plumber’s putty from the countertop. Before you begin installing a new kitchen sink, ensure that the surface is clean.

Additionally, wipe up any water that may have leaked from the sink during removal.
