Measuring the Existing Sink

Start with measuring your older sink. By doing this, you’ll know the exact positioning of the drains. Also, you’ll be able to make any adjustments upon installation.

In case the new sink comes with different dimensions from the old one, or its drain locations are different, then you may have to make additions or adjustments on the countertop.

You can hire a professional to make alterations on the countertop, especially if it comprises of sensitive materials such as natural stone and stainless surface.

 

Examining the Hardware

You need to decide whether you’ll be replacing the fixtures. In case you’ll need to replace any hardware fixtures, do it when installing a new sink.

If you’ll be adding new fixtures such as a hot water sink or a soap dispenser, you might have to drill extra holes in the sink.

Most sinks come with 1-4 factory drilled holes. Avoid altering the sink by investing in a sink that comes with the number of holes you’ll need for additional fixtures.

Removing the Old Kitchen Sink

There are several steps required to remove the older sink. Here are the necessary steps:

  1. Turn off the water: Start with turning off all the water supplies connected to the sink. Most cold and hot water supplies for the sink are located just below it. In the event that you are unable to trace the valves, simply shut off the main water supply. You would also want to take a picture of your valve and pipe configuration before doing any disconnections. This will assist you when reconnecting the water lines upon installing the new sink.
  2. Turn on the faucet: Relieve the water pressure by turning on the sink faucet. This will drain the water line.
  3. Disconnect the disposal and supply lines: Use a wrench to detach the supply lines. You can set a bucket to catch dripping water. Once done, turn off the disposal circuit. Then unplug it. Next, detach the sink’s P-trap. Allow it to drain. You can set a bucket to collect the drip. Next, remove the disposal motor as per the instructions of the manufacturer.
  4. Loosen the sink: Look for the clips holding the sink from below. You can take a screwdriver and use it to turn each clip towards the sink. Then take a razor and cut the caulking around the sink.
  5. Remove the old sink: Just push the old sink from beneath. Do this until it separates from the countertop. If it can’t move, use a razor to remove the sink’s caulking. Then confirm that the clips face the sink bowl. Use a sharp putty knife to scrape any leftover buildup or grime on the countertops.

Installing the New Sink

It’s not really difficult to add a new sink. Follow this simple guide:

  1. Checking the new fit: Start with placing the new sink onto the existing hole to double check whether it fits properly. In case it is over or undersize, contact a specialist. Kitchen pros have the necessary experience to adjust the countertop to fit any sink size.
  2. Attaching the clips: Simply flip the new countertop and attach all the clips. Make sure the clips face towards the sink bowl.
  3. Attaching the strainer: Take some plumber’s putty and roll it to form a thin putty strip. Apply the roll around the strainer’s edges and around the drain. Put the strainer in the sink drain while pressing it inwards.
  4. Adding the gaskets: Next, place the sink sideways and put the rubber gaskets on the drain. Then thread the flange. Do this until all the drains are covered. Remove any excess putty that may be pushed into the drain or sink bowl.
  5. Installing the sink: Take the mounting bracket of the sink and screw it. Apply some silicone caulk underneath the sink. Lower the sink onto the countertop. Ensure it is aligned squarely. Next, rotate the clips towards the sink bowl. This will secure it firmly.
  6. Sealing the outer part of the sink: Use silicone caulk to seal the outer part of the sink. Wipe any excess caulk using a slightly wet rag.
  7. Attaching fixtures: Reattach the water supplies and disposal lines. Attach all extra fixtures such as hot water supply and soap dispensers. In case you are not sure about how to reattach the sink fixtures, call a professional for assistance. Any mistakes when installing sink fixtures may result in leakages, reduced efficiency, and malfunctions.
  8. Reconnecting the P-trap: Finally but not least, screw the P-trap in place. Then turn on the sink’s electrical and water supplies.
