When installing a kitchen sink, begin by performing a test fit. The process involves manually lowering the sink into the countertop. Position the new sink to the hole in the counter top to make sure that it is suitable.
If the countertop opening is small, then you might need to make adjustments using a tile cutter, tile or jigsaw. Also, if the new sink is built with a larger opening than the countertop opening, you need also to modify the hole in the countertop.
To do this, invert the sink on where you want to fix it to the countertop and trace the outline. Thereafter proceed to create a cutout using a jigsaw.
To allow attachment of clips, you need to remove the basin from the countertop hole.

Tighten the clamp which holds the pipe in position using a screwdriver. If you are using a garbage disposer, use the manufacturer’s guide regarding installing a kitchen sink. After that, insert the discharge line and tighten up the clamp using an appropriate tool.
Attach the dishwasher to the disposer.
Fix the disposer discharge line to the sink drain line and fix back the P-trap to the drain configuration.
If the old drain pipe does not fit well with the new sink, try to make some modification. Here are the main types of modifications to encounter when installing a kitchen sink:
When A Pipe Is Longer Than Required
- Determine the correct length needed. – Add an allowance to the length measurement to provide a tight connection.
- Cut the pipe using a hacksaw. You should ensure that you wear safety glasses before beginning the cutting process.
- With the washer on the water line, slide a nut onto the water line over the washing machine.
- Holding the pipe in position, close the slip nuts to the correct fitting.
When The Pipe Is Short
- Measure the correct length needed.
- Add an allowance to the length measured to provide a tight connection.
- Buy a new pipe ensuring that it has the correct size of the diameter.
- If the pipe is extra-long, use a hacksaw to reduce it to the correct size. You should put on safety glasses every time you are cutting the pipe to avoid exposing yourself to danger.
- Position the washing machine on the pipe followed by sliding the slip nut over the washer until it holds correctly.
- If you require a slip nut to place it on the opposite end, then you should insert the slip pipe ensuring that it is facing the correct direction. After that, you can add a dishwasher.
- Holding the pipe in position, screw the slip nuts to the right equipment.
If You Require A Bend
Start by trying to rotate the outlet tree, P-trap or other pipes to position it correctly. Alternatively, you can use an elastic extension pipe for linking. Bend the pipe until you achieve a suitable position and use slip nuts and rubber washers to fix it to other plumbing components.
Apply a sealant around the outer edge of the sink using a caulk gun. Ensure that the perimeter is well sealed.
Finally, search for leaks with your dry hand in all parts of the connections. Plug in power to the dispenser and turn on water and check if there are any leaks after installing a kitchen sink.
