Bathroom Sink Drain Pipe Leaking At Connection

A leaking drain pipe under a bathroom sink can be a major annoyance, causing water damage to the floor and cabinets. If you're experiencing this problem, don't panic! Here's a step-by-step guide on how to fix a leaking bathroom sink drain pipe at the connection:

1. Gather your tools and materials

Before you start, make sure you have all the necessary tools and materials for the job:

Adjustable wrench
Slip joint pliers
Plumber's putty
Teflon tape
Replacement drain pipe (if needed)

2. Turn off the water supply

The first step is to turn off the water supply to the sink. This will prevent water from leaking out of the pipe while you're working.

3. Remove the old drain pipe

Once the water is turned off, you can remove the old drain pipe. To do this, loosen the slip nuts that connect the pipe to the sink and the drain assembly.

4. Clean the connection points

Once the old drain pipe is removed, clean the connection points on the sink and the drain assembly. This will remove any debris or old sealant that could prevent the new pipe from sealing properly.

5. Apply plumber's putty

Apply a bead of plumber's putty around the base of the new drain pipe. This will help to create a watertight seal between the pipe and the sink.

6. Wrap the threads with Teflon tape

Wrap the threads on the new drain pipe with Teflon tape. This will help to prevent leaks from occurring at the connection.

7. Install the new drain pipe

Insert the new drain pipe into the connection point on the sink. Hand-tighten the slip nuts until they are snug.

8. Use an adjustable wrench to tighten the slip nuts

Use an adjustable wrench to tighten the slip nuts on the drain pipe. Be careful not to over-tighten the nuts, as this could damage the pipe or the sink.

9. Turn on the water supply and check for leaks

Once the drain pipe is installed, turn on the water supply and check for leaks. If there are any leaks, tighten the slip nuts further until they stop.
