Plumbing the sink

Step by Step Guide: How to Install an Outdoor Kitchen Sink

If you have to repair an old outdoor kitchen at some point you will have to install the sink.

Like us, we did not know how to go about it either. With more time than money we finally struggled through it.

This easy-to-follow guide will get you started. You’re Welcome, we hope it helps you!

Preparation

Before starting this project, check that you have the right kind of sink used for replacement. This install is for a drop in sink only.

It would be a bummer to pull it out the old sink only to find the new one didn’t fit. Or it’s different. It has to be the same size or a bit bigger. This is so we can fit it back in the same size cutout.

Now go through the instructions in the manufacturer’s manual for the exact fitting instruction.

It will also have the cutout template with the correct fit for that model.

Step 1. Measure both Sinks

Take the measurements of the existing sink. If there is a difference in measurements between the existing sink and your new sink, then the countertop opening and/or plumbing may need to be modified.

Step 2. Check the Faucets

Decide if the faucet will also be replaced whenever components like soap dispenser, sprayer, on-demand hot water tap or filtered water cap are being installed.

Standard sinks normally have 1, 2, 3, or 4 holes on the back lip for a faucet and other components.

Installing a new faucet plus other components is easier if done when installing a new singer because accessing the hardware is more conveniently done with the sink coming out of the counter top.

Step 9. Check the cut out

Place the new cut out template on the countertop hole to check that it fits.

If the dimensions of the new countertop opening are bigger than the current one, flip the sink upside down to where you want it on the countertop.

Mark the outline and make a new cutout using a jigsaw.

Step 10. Test the new sink

Take the sink out of the box and turn the clasp inward facing the bowl.

Position the sink in the cut out and make sure it fits. Remove and place the sink upside down on the bench.

Step 11. Fit the new sink

Make sure the manufactures seal is in tact and remove any application tape. Otherwise, apply a small bead of clear silicone around the edge of the new sink.

Gently fit the sink back in place. Underneath the sink, there is a plated attachment that is outwardly clipped.

Make sure that it is adequately fastened with screws.

Get rid of excess putty with a soft towel.

Step 12. Reconnect plumbing

Reinstall the dishwasher drain if applicable.

Connect the Drain pipes and re-attach the P-trap. Apply a little bead of sealant to the pipe perimeter.

Step 13. Turn on water

Reconnect the power to the disposer. Turn on the water and check for leakage.


Your Fitting’s Are Different – Help?

In case your old drain pipes do not fit your new sink, you can adjust in these ways.

Where the pipe is too long.

  • Measure the needed length
  • Extend a little thee measured length to make sure the connection is tight.
  • Cut the pipe using a hacksaw wearing safety glasses.
  • Put a washer on the pipe, slide the slip nut onto the channel towards the right direction, thereafter, add washers.
  • Fasten the channel in position and screw the nut to the right fittings.

In case a pipe is too short:

  • Check the needed length
  • Leave an extra length to the actual length to ensure the connection is tight.
  • Buy a longer pipe. Verify that the new channel has the right diameter.
  • Cut the pipe using a hacksaw if it is longer than necessary.
  • Put the washer on the pipe, and then slide the slip nut onto the channel towards the right direction. Thereafter add a washer.
  • Screw the slip nuts to the correct fittings as you hold the pipe in place. In order to make a bend first try turning the outlet tree, P-trap or any other types of pipe to align adequately. If that fails, using an extension pipe that is flexible would easily make the connection. Bend the pipe to the preferred position and using rubber washers and slip nuts, attach it to other plumbing.

Learning how to install a kitchen sink yourself would not only save cost but would also help you become more efficient as an individual.

However, it is important that you understand all the risk so that you know when to hire a professional and when to do it yourself.
