How to Fix a Slow-Draining Sink (Before You Call a Plumber)

If your sink is draining slowly, don’t panic — there are a few simple fixes you can try at home before calling in a professional.

Start With the Easiest Solution: Baking Soda & Vinegar

Begin by pouring baking soda followed by vinegar down the drain. This natural combination can help break up light clogs caused by grease, soap residue, or buildup. Let it sit for a few minutes, then rinse with hot water. You may need to repeat the process once or twice for best results.

Remove and Clean the P-Trap

If the problem persists, it’s time to check the trap under your sink. Clear out the space beneath the cabinet and place a small bucket under the drainpipe to catch any water or debris.

Carefully loosen the bolts or twist off the trap by hand. Check for buildup and remove any gunk from the trap and exposed pipes. This area commonly collects hair, soap scum, and debris that slow drainage.

Use a Drain Snake

Still draining slowly? A drain snake can help reach clogs farther down the pipe. Insert the snake into the drain, twist gently, and pull out any trapped hair or debris. This method is especially effective for stubborn blockages that aren’t visible in the trap.

Flush and Test

Once everything is cleared, reassemble the pipes and run hot water through the sink to flush the system. In most cases, this will restore normal drainage.

When to Call a Professional

If your sink continues to drain poorly, the clog may be deeper in the plumbing system. At that point, it’s best to call a professional plumber to avoid further issues.

With a little patience and elbow grease, your sink should be back to working like new — and if it’s not, call the professionals at JSP to help.
