What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Identify the Problem

Take note of the symptoms your sink is exhibiting. Is there water pooling? Is the faucet leaking? Understanding the specific issue is the first step.

2

Check for Leaks

Inspect all connections and pipes under the sink for signs of leaks. Look for dampness or water stains around the fittings.

3

Test the Drainage

Run water in the sink and observe the draining process. If the sink drains slowly, it may indicate a clog or an issue with the drain slope.

4

Inspect the Faucet

Examine the faucet for any irregularities. If it is not functioning properly, consider cleaning the aerator or replacing the cartridge.

5

Check for Odors

If you detect unpleasant odors, inspect the drain for food debris or a dry P-trap. Clean as necessary to eliminate the smell.

Pro Tip
Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.

Common Questions
What should I do if my sink is leaking?
If your bathroom sink is leaking, first check all connections and fittings for tightness. Look for any visible cracks in the sink itself. If the leak persists, you may need to replace washers or seals. In severe cases, it could indicate a structural issue or a damaged pipe that requires professional assistance.
Why is my sink draining slowly?
A slow-draining sink could indicate a clog in the drain line or an improperly installed drain slope. You can try using a plunger or a drain snake to clear minor clogs. If these methods do not resolve the issue, it may require a professional plumber to inspect and fix the problem.
How can I level my sink?
To level your sink, check the installation brackets and adjust them as necessary. If the floor is uneven, you can use shims to raise the sink to the correct height. Ensuring the sink is level is important for proper drainage and to prevent future leaks.
What causes odors coming from my sink?
Odors from your sink often arise from food debris trapped in the drain or a dry P-trap. Regularly clean your drain and ensure that the P-trap is filled with water. If odors persist, it may indicate a sewer gas leak, requiring immediate professional attention.
