Replace Moen Bathroom Sink Drain

Replacing a Moen bathroom sink drain is a relatively simple task that can be completed in about an hour. By following these step-by-step instructions, you can easily replace your old drain and restore your sink to proper working order.

Materials you'll need:

New Moen bathroom sink drain
Adjustable wrench
Plumber's putty
Rags or towels
Bucket

Step 1: Turn off the water supply

Before you begin, it's important to turn off the water supply to your sink. You can do this by locating the shut-off valves under the sink and turning them clockwise until they are fully closed.

Step 2: Remove the old drain

Once the water supply is turned off, you can begin removing the old drain. Start by placing a bucket under the sink to catch any water that may leak out. Then, use an adjustable wrench to loosen the large nut that holds the drain in place. Once the nut is loose, you can carefully pull the old drain out of the sink.

Step 3: Clean the drain hole

Once the old drain is removed, take a moment to clean the drain hole. Use a rag or towel to wipe away any debris or old plumber's putty. You may also want to use a small brush to scrub the inside of the drain hole to remove any mineral deposits.

Step 4: Apply plumber's putty to the new drain

Before installing the new drain, you need to apply a bead of plumber's putty around the base of the drain flange. This will help to create a watertight seal between the drain and the sink.

Step 5: Install the new drain

Once the plumber's putty is in place, you can carefully insert the new drain into the drain hole. Be sure to align the drain flange with the sink hole before pushing it into place. Once the drain is in place, tighten the large nut by hand until it is snug. You can then use the adjustable wrench to further tighten the nut, but be careful not to overtighten it.

Step 6: Turn on the water supply

Once the new drain is installed, turn on the water supply and check for leaks. Open the faucet and let the water run for a few minutes. If you see any leaks, tighten the nut a little more using the adjustable wrench.

Step 7: Clean up

Once the drain is installed and there are no leaks, you can clean up the area around the sink. Use a rag or towel to wipe away any excess water or plumber's putty. You may also want to use a disinfectant to clean the area around the drain to prevent the growth of mold and mildew.

Replacing a Moen bathroom sink drain is a simple task that can be completed in about an hour. By following these step-by-step instructions, you can easily replace your old drain and restore your sink to proper working order.
