There are many different problems that can arise as a result of having a leak in your bathroom sink drain. Whether your sink will not properly hold the water that you fill it up with, or if it continuously leaks and causes a mess on the floor, you'll want to repair the source of the leak as quickly as you can in order to properly prevent the matter from getting worse or causing any further damage. Read on for a brief how to guide on how you can repair a leaky bathroom sink drain in your home.

Step 1 - Check the Stopper

One of the primary reasons why a bathroom sink drain tends to leak is if the stopper isn't working properly. Stoppers come in a variety of different types and sizes, as well as unique designs, so you'll need to look at yours carefully in order to properly examine it. Close the stopper completely and fill up the sink with water. Observe what happens. If necessary, adjust the stopper by turning it to be sure that it has securely fit into place. If the stopper isn't working properly, you'll need to purchase and install a replacement. Otherwise, the leak is coming from some other source; in this case, tape the stopper up so that the drain is open.

Step 2 - Look Under the Sink

Use your flashlight to look underneath the sink. You'll need to track down both the control and the lift rods. These are responsible for moving the stopper in and out of position. When you find them, examine the bolt that is attaching the rod to the mechanism which moves it. In particular, you should be looking for the control rod, as this is what will tend to cause a greater number of problems that result in leaks in general.

Step 3 - Adjust the Bolts

Locate the nut and bolt system on the control rod that helps to attach it into place. If the bolt becomes loose, the rod may not be able to move properly in order to put the stopper into place. Tighten the bolt with your monkey wrench and ensure that the rod still has a full range of motion that is available to it. After this, check on the status of the leak once again to see if it is repaired.

Step 4 - Check the Pipes

In some cases, leaks can be a result of malfunctions in the pipes themselves. If the above steps don't properly seal up the leaky bathroom sink drain, check the pipes for connection points that might be missing. You may need to seal up the pipes or replace them entirely in order to completely eliminate any trace of the leak.
