Is your old bathroom sink drain pipe constantly leaking or causing clogs? It may be time to replace it. The process can seem daunting, but with the right tools and a little bit of know-how, you can easily replace your old bathroom sink drain pipe and have it functioning like new. Here are ten steps to help guide you through the process.Replace Old Bathroom Sink Drain Pipe
Before you begin, make sure you have all the necessary tools. You will need a pipe wrench, pliers, a hacksaw, a bucket, plumber's putty, and a new sink drain pipe kit. It's also a good idea to have some towels on hand to clean up any spills or messes.Step 1: Gather Your Tools
The first step is to turn off the water supply to your sink. This is usually done by turning the shut-off valves located under the sink clockwise until they are fully closed. If your sink doesn't have shut-off valves, you will need to turn off the main water supply to your home.Step 2: Turn Off the Water
Using your pipe wrench and pliers, disconnect the drain pipe from the sink and the wall. You may need to use some force to loosen the connections. Once the pipe is disconnected, remove it from the sink and set it aside.Step 3: Disconnect the Drain Pipe
The drain flange is the circular piece that sits on top of the sink and connects to the drain pipe. Using your pipe wrench, unscrew the flange from the sink. If you have trouble removing it, you may need to use a hacksaw to cut it off.Step 4: Remove the Old Drain Flange
With the old drain flange removed, you can now thoroughly clean the sink and the drain opening. Use a mild cleaner and a scrub brush to remove any buildup or residue.Step 5: Clean the Sink and Drain Opening
Next, take your plumber's putty and roll it into a long, thin rope. Place the rope around the bottom edge of the new drain flange. This will create a watertight seal when you install the new flange.Step 6: Apply Plumber's Putty
Place the new drain flange into the drain opening and press down to create a seal with the plumber's putty. Make sure it is centered and level before moving on to the next step.Step 7: Install the New Drain Flange
Now you can attach the new drain pipe to the flange. Make sure all connections are tight and secure. You may need to use your pliers to tighten them fully.Step 8: Attach the New Drain Pipe
With the new drain pipe in place, you can now reconnect it to the sink and the wall. Again, make sure all connections are tight and secure.Step 9: Reconnect the Drain Pipe
