How to Fix a Hole in a Pipe Under a Bathroom Sink

A leaky pipe under a bathroom sink can be a frustrating and potentially damaging problem. If left unchecked, it can lead to extensive water damage and costly repairs. Fortunately, fixing a small hole in a pipe is a relatively simple task that can be completed in a few hours with the right tools and materials.

Step 1: Gather Your Tools and Materials

Before you begin, you'll need to gather the following tools and materials:

Adjustable wrench
Pipe cutter
Replacement pipe section (same size and type as the damaged pipe)
Pipe sealant
Sandpaper
Rags

Step 2: Turn Off the Water Supply

Before you start working on the pipe, it's important to turn off the water supply to the sink. Locate the shut-off valves under the sink and turn them clockwise until they are tightly closed.

Step 3: Inspect the Damage

Once the water is turned off, inspect the damaged pipe to determine the extent of the hole. Use a rag to wipe away any water or debris from the area.

Step 4: Cut Out the Damaged Section

Using a pipe cutter, carefully cut out the damaged section of the pipe. Be sure to make clean, straight cuts.

Step 5: Clean the Pipe Ends

Use sandpaper to lightly sand the ends of the pipe where the new section will be connected. This will help to ensure a good seal.

Step 6: Apply Pipe Sealant

Apply a liberal amount of pipe sealant to the ends of the replacement pipe section. Use your finger to spread the sealant evenly around the entire circumference.

Step 7: Insert the Replacement Section

Insert the replacement pipe section into the ends of the existing pipe. Hand-tighten the connection as much as possible.

Step 8: Tighten the Connection

Use an adjustable wrench to further tighten the connection. Be careful not to overtighten, as this can damage the pipe.

Step 9: Turn on the Water Supply

Slowly turn on the water supply to the sink. Check for any signs of leaks at the connection. If you find a leak, tighten the connection further and check again.

Step 10: Clean Up

Once the repair is complete, clean up any excess sealant or water. You may also want to run the water for a few minutes to flush out any debris.

Fixing a small hole in a pipe under a bathroom sink is a relatively straightforward task that can be completed in a few hours. By following these steps, you can save yourself the time and expense of calling a plumber.
