How to Replace a Bathroom Drain and Sink Trap

Replacing a bathroom drain and sink trap is a relatively simple plumbing task that can be completed in a few hours. This article will provide you with step-by-step instructions on how to replace a bathroom drain and sink trap, as well as some tips and tricks to make the job easier.

Tools and Materials You Will Need

Adjustable wrench
Plumber's putty
New bathroom drain
New sink trap
Bucket
Flashlight

Step-by-Step Instructions

1. Turn off the water supply to the sink. This is usually done by turning the water supply valves located under the sink. If there are no valves under the sink, you will need to turn off the main water supply to the house.

2. Remove the old drain. The drain is held in place by a nut that is located under the sink. Use an adjustable wrench to loosen the nut and remove the old drain.

3. Clean the drain hole. Once the old drain is removed, clean the drain hole with a damp cloth. Remove any debris or old sealant.

4. Apply plumber's putty to the new drain. Roll a small amount of plumber's putty into a rope and apply it to the bottom of the new drain. The plumber's putty will help to create a watertight seal.

5. Install the new drain. Insert the new drain into the drain hole and tighten the nut from under the sink. Do not overtighten the nut, as this could damage the drain.

6. Install the new sink trap. The sink trap is a U-shaped pipe that connects the drain to the sink. To install the new sink trap, first remove the old sink trap by loosening the nuts that hold it in place. Then, insert the new sink trap into place and tighten the nuts. Do not overtighten the nuts, as this could damage the sink trap.

7. Turn on the water supply to the sink. Check for leaks around the drain and sink trap. If there are any leaks, tighten the nuts until the leaks stop.

Tips and Tricks

If you have a flashlight, use it to inspect the drain hole and sink trap for any debris or damage.
If you are replacing the drain and sink trap on a sink that is located in a tight space, you may need to use a pair of pliers to tighten the nuts.
If you are not comfortable replacing the drain and sink trap yourself, you can call a plumber to do it for you.
