If you are trying to install a double kitchen sink drain in your home, you may be confronted with a series of pipes that you must plumb correctly. Fitting a double sink drain with a dishwasher attachment or other utility attachment can be even more confusing, but you can easily put the basic drain together. In Part 1 of this guide, you will learn how to fit the drains to the sink bowl, attach the trap arms to the wall sub and fit the connections to the drain tailpiece.

Step 1 - Turn Off the Water Supply

Before you proceed, you should take care to turn off your water supply at the mains pipe. Drain water from the area you wish to use, in this case the kitchen. Don't forget to turn the water back on once you have finished the drain water installation.

Step 2 - Install the Drains

You need to ensure that you have enough space in your kitchen sink drain hole for the drain attachment that you require. It is best to find a drain of a similar make to the sink that you own. When you are ready, you can then add a layer of putty around the edge of the drain, and ensure that it is pressed down into the drain hole. The putty will help to keep the drain in place. Once this is done, you can then proceed to fitting the drain.

Step 3 - Add the Trap Arm

The next part of the installation involves fitting the trap arm. This is a straight piece which fits beneath the sink. The trap arm should be installed below a straight pipe attachment. The trap arm should be fitted to the drain-stub, which is done using a suitable washer, and a slip nut. The washer usually has a beveled edge which then can be installed against the side of the drain stub. you can trim down the trap arm if necessary.

Step 4 - Attaching the T-Fitting

Once the drain is added, you can then attach a small piece of pipe known as a tailpiece to the end of the drain below the sink. Screw this into place using the nut, and then add the T-fitting to this tailpiece using a slip washer. Level it up to the bevelled edge of the washer, s that it grips the pipe tightly. You can then fit it into position. Some pipe grease on the edge of the T-fitting will help it to move more easily.
