However, many people don’t know that they can fix their sinks themselves!

Here’s a step-by-step guide so you can fix your sink in no time.

Determine the Type of Leak

Fix the Problem

The solution or fix for the leak depends on the type of leak. In this section, we’ll break down what types of leaks require what steps for a fix.

Faucet Leaks

Sometimes the faucet is the source of the problem, rather than the drain or seal. Always check the faucet first, since it’s the easiest kind to find.

The good news is that these kinds of leaks are extremely easy to see because they flow down the back of the faucet and pool water behind the sink. In this case, all you need to do is replace the faucet itself.

Drain Seal Leaks

The next thing to check is the drain seal. You’ll know it’s broken if your sink cannot hold water without leaking. It’s very simple to replace as well:

1. Gently remove the old drain seal with a pair of pliers. If you don’t have pliers, you may use a fork.
2. Carefully apply new adhesive around the bare drain. Be careful not to apply too much.
3. Replace the seal, making sure to apply it centered around the drain.

Drain seal leaks are not uncommon or difficult to fix. In fact, you can find replacement parts for the seal at your local hardware store for less than $5. Just make sure to apply it correctly so you don’t need to reapply it later.

If you’re sure it’s not a faucet or a seal leak, check if the problem is the drain itself. These happen when water comes out of the drain itself while the sink is emptying, resulting in a cabinet full of water. Most of the time, this is a very easy fix and you just need to tighten the nut for the pipe.

If you’ve tightened the nut and the sink still leaks, take these next steps:

1. Verify that Plumbers Putty was used when installing the drain outlet flange.
2. Ensure that the gasket/rubber sealing washer is completely flat.
3. If everything looks okay and the sink is still leaking, take the entire thing apart and inspect every part to see if it’s cracked or damaged. Replace any damaged parts, then reinstall it.

If these steps don’t work, double-check to make sure the leak is coming from the drain or elsewhere.
