How to Repair a Leak Under the Sink

A leak under the sink can be a major headache, but it's one that you can usually fix yourself with a few simple tools and a little bit of time. Here's a step-by-step guide to help you repair a leak under the sink:

Step 1: Turn Off the Water Supply

The first step is to turn off the water supply to the sink. There will usually be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to turn off the water.

Step 2: Locate the Leak

Once the water is turned off, you need to locate the leak. Check all of the pipes and fittings under the sink for any signs of water damage or dripping water. Once you've found the leak, you can start to repair it.

Step 3: Tighten Loose Fittings

If the leak is coming from a loose fitting, you can simply tighten it with a wrench. Be careful not to overtighten the fitting, as this could damage the pipe.

Step 4: Replace Worn Washers

If the leak is coming from a worn washer, you will need to replace it. Washers are small, rubber or metal disks that create a watertight seal between two pipes or fittings. To replace a washer, simply remove the old washer and replace it with a new one.

Step 5: Repair Cracked Pipes

If the leak is coming from a cracked pipe, you will need to repair or replace the pipe. To repair a cracked pipe, you can use a pipe repair clamp. Pipe repair clamps are available at most hardware stores.

Step 6: Turn the Water Supply Back On

Once you have repaired the leak, you can turn the water supply back on. Slowly turn on both valves, and check for any leaks. If there are no leaks, then you have successfully repaired the leak under the sink.
