How To Replace Your Bathroom Sink Drain

How to Replace Your Bathroom Sink Drain

A clogged or faulty bathroom sink drain can be a major inconvenience. Thankfully, replacing a sink drain is a relatively simple plumbing task that can be completed in a few hours. Here's a step-by-step guide on how to do it:

Tools and Materials You'll Need:

New sink drain assembly
Adjustable wrench
Pliers
Bucket
Caulk gun
Plumber's putty or silicone sealant
Screwdriver (optional)

Step 1: Turn Off the Water Supply

Before starting any plumbing work, it's essential to turn off the water supply to the sink. Locate the shut-off valves under the sink or behind the toilet and turn them clockwise to close.

Step 2: Remove the Old Drain Assembly

Place the bucket under the sink to catch any water that may drain out. Use an adjustable wrench to loosen the large nut that holds the drain assembly in place. Once loose, carefully remove the assembly by pulling it up from the sink.

Step 3: Clean the Sink Opening

Once the old drain is removed, clean the sink opening of any debris or old caulk. Use a damp cloth or sponge to wipe away any residue.

Step 4: Apply Plumber's Putty or Silicone

Apply a generous bead of plumber's putty or silicone sealant around the underside of the new drain assembly's flange. This will create a watertight seal between the drain and the sink.

Step 5: Install the New Drain Assembly

Carefully position the new drain assembly over the sink opening and press it down to set the putty or sealant. Use the adjustable wrench to tighten the large nut until it's snug but not overtightened.

Step 6: Connect the Drain Pipe

Locate the drain pipe under the sink and inspect the old connection. Use pliers to loosen the old connection and remove the pipe. Clean the pipe ends and apply a light coating of plumber's putty or sealant. Connect the drain pipe to the new drain assembly and tighten the connection.

Step 7: Reconnect the Water Supply

Turn on the water supply and check for leaks around the drain assembly and the connection to the drain pipe. If there are any leaks, tighten the connections until the leaks stop.

That's it! You have successfully replaced your bathroom sink drain. If you encounter any difficulties during the process, don't hesitate to contact a licensed plumber for assistance.
