How To Plumbing In A New Bathroom Sink Drain

If you're in the middle of a bathroom remodel or installing a new sink, you'll need to know how to plumb in a new drain. It's not a difficult task, but it does require some basic plumbing skills. Here's a step-by-step guide to help you get the job done right.

Tools and Materials:

Adjustable wrench
Plumber's putty
Teflon tape
P-trap
Sink drain
Putty knife

Step 1: Remove the old drain.

If you're replacing an old drain, start by removing the old one. Use an adjustable wrench to loosen the nuts that hold the drain in place. Once the nuts are loose, you can pull the drain out of the sink. Be careful not to drop the nuts down the drain!

Step 2: Apply plumber's putty.

Before you install the new drain, you'll need to apply a bead of plumber's putty around the base of the drain flange. The plumber's putty will help to create a watertight seal and prevent leaks.

Step 3: Install the drain flange.

Once you've applied the plumber's putty, put the drain flange in place. The drain flange is the part of the drain that fits over the drain hole in the sink. Tighten the nuts that hold the drain flange in place. Be careful not to overtighten the nuts, or you could crack the sink.

Step 4: Install the P-trap.

The P-trap is a U-shaped pipe that connects the drain flange to the sink drain. The P-trap traps water, which helps to prevent sewer gases from escaping into your bathroom. To install the P-trap, simply hand-tighten the nuts that hold the P-trap in place.

Step 5: Install the sink drain.

The sink drain is the part of the drain that fits into the drain hole in the sink. To install the sink drain, simply insert the drain into the hole and tighten the nut that holds the drain in place. Be careful not to overtighten the nut, or you could crack the sink.

Step 6: Test the drain.

Once you've installed the drain, test it by running water into the sink. Check for any leaks. If you see any leaks, tighten the nuts on the drain flange and P-trap until the leaks stop.

That's all there is to it! If you follow these steps, you'll be able to plumb in a new bathroom sink drain in no time.
