How To Connect Sink To Drain

Connecting a sink to a drain is a relatively simple plumbing task that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.

Materials You'll Need

Sink
Drainpipe
P-trap
Slip joint nuts
Washers
Teflon tape
Adjustable wrench
Plumber's putty

Step-by-Step Instructions

1. Prepare the sink. Start by placing the sink in its desired location. Apply a bead of plumber's putty around the sink's drain hole. This will help to create a watertight seal.

2. Install the P-trap. The P-trap is a curved pipe that connects the sink's drain hole to the drainpipe. Place the P-trap under the sink and connect it to the drain hole using slip joint nuts and washers. Tighten the nuts until they are snug.

3. Connect the drainpipe. The drainpipe is a straight pipe that connects the P-trap to the drain. Cut the drainpipe to the desired length and connect it to the P-trap using slip joint nuts and washers. Tighten the nuts until they are snug.

4. Wrap the drainpipe with Teflon tape. Teflon tape is a self-adhesive tape that helps to create a watertight seal. Wrap the drainpipe with Teflon tape in a clockwise direction, starting from the bottom of the pipe. Overlap the tape by at least two layers.

5. Connect the drainpipe to the drain. Insert the drainpipe into the drain and tighten the slip joint nut until it is snug. Do not overtighten the nut, as this can damage the drainpipe.

6. Test the drain. Once the drain is connected, run water into the sink and check for leaks. If you see any leaks, tighten the slip joint nuts until the leaks stop.

Tips

Use a level to make sure that the sink is level before you tighten the slip joint nuts.
If you are not sure about the size of the drainpipe that you need, consult with a plumber.
Do not use excessive force when tightening the slip joint nuts. Overtightening the nuts can damage the drainpipe.
