How to Replace an Old Sink and Install a New Sink?

There are many steps when wanting to replace the kitchen sink and installing a new kitchen sink drain. When performing the job it is important all steps are followed correctly to prevent a future problem, such as a leaky sink. Follow these steps to ensure when the new sink is replaced and installed all parts function perfectly:

Measuring the Old SInk

Gathering the dimensions of the old sink is important to make sure the new sink bought will fit into the area. Unless new cabinetry is being installed, the new sink should be the correct size so it can be installed perfectly. It is also important so the drains can fit properly and if any adjustments to the pipes or drain can be made. Hiring a professional to fix or adjust the countertop so the new sink will fit might have to be made as well.

Replacing the Old Sink

When it comes to the part to replace the kitchen sink follow these steps:

  1. Turn off the water supply connected to the sink. These hot and cold water links are located below the sink. When the valves cannot be found then having to turn off the water from the main water supply might be needed. While the main water supply line is turned off this means that water to the home will be temporarily unavailable. 
  2. Turn on the tap faucet to have the water pressure relieved. The water line will be drained and so when replacing the kitchen sink water will not create a mess.
  3. Disconnect the supply and disposal lines from the sink using an adjustable wrench. Have a bucket to catch any remaining water and when the process is complete turn off the garbage disposal circuit and unplug it if one is connected. Remove the sink P-trap, have it drain then remove the disposal motor from the sink.
  4. Loosen the existing sink by using a screwdriver to loosen the clips under the sink and cut the caulking around the edge of the sink. 
  5. Remove and take off the sink from pushing up on it from underneath.

Installing the New Sink

To install the kitchen sink the steps are simple:

  1. Place the new sink in the existing hole and check to see that all fits correctly. If the sink is too small or large then organise a professional to adjust the surroundings.
  2. Attach all the slips of the new sink into the countertop, ensure these clips face towards the sink drain.
  3. Attach the strainer by adding some plumber’s putty and rolling a thin strip. Have this thin strip of putty around the drain and strainer’s edges. Place the strainer into the sink and press inwards.
  4. Add the gasket by first placing the sink sideways and place them on the drain. After this thread the flange until all the drains are covered and then remove any excess putty.
  5. Install the kitchen sink on the mounting bracket and screw it in. After this underneath the sink apply silicone caulk and lower the sink carefully on the countertop. Make sure everything is aligned and rotate the clips towards the sink blow to secure it. Add some silicone caulk to the countertop of the sink to seal it. 
  6. Attach the disposal lines, water supply lines, hot water supply and garbage disposal unit, such as an InSinkErator. Reconnect the P-trap and turn the sink’s electrical and water components and perform tests to make sure the sink works perfectly.
