How to Replace a Bathroom Sink Drain

Replacing a bathroom sink 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 * New sink drain * Plumber's putty * Adjustable wrench * Basin wrench * Rags ### Step 1: Turn Off the Water Supply The first step is to turn off the water supply to the sink. There are usually two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to shut off the water. ### Step 2: Remove the Old Drain Once the water supply is turned off, you can remove the old drain. Place a rag under the drain to catch any water that may leak out. Use an adjustable wrench to loosen the nut that holds the drain in place. Once the nut is loose, you can remove the old drain by hand. ### Step 3: Apply Plumber's Putty to the New Drain Before installing the new drain, you need to apply plumber's putty to the base of the drain. Plumber's putty is a sticky substance that helps to seal the drain and prevent leaks. To apply plumber's putty, simply roll a small piece of putty into a ball and place it around the base of the drain. ### Step 4: Install the New Drain Once the plumber's putty is in place, you can install the new drain. Insert the drain into the sinkhole and tighten the nut by hand. Use the adjustable wrench to further tighten the nut, but be careful not to overtighten it. ### Step 5: Connect the Drain to the P-Trap The next step is to connect the drain to the P-trap. The P-trap is a U-shaped pipe that helps to prevent sewer gases from entering the bathroom. To connect the drain to the P-trap, simply insert the drainpipe into the P-trap and tighten the nut. ### Step 6: Turn On the Water Supply Once the drain is connected, you can turn on the water supply. Check for leaks around the drain and the P-trap. If you find any leaks, tighten the nuts accordingly. ### Tips * If you have a double sink, you will need to replace both drains. * It is a good idea to replace the P-trap at the same time that you replace the drain. * If you are not comfortable working with plumbing, it is best to hire a plumber to replace the drain for you.
