What are the common causes of kitchen sink leaks?

Leaks at a kitchen sink often stem from worn-out washers or O-rings, loose plumbing connections, corroded pipes, cracked sink components, or improper sealing of parts like the drain flange.

How do I identify where the leak is coming from under my sink?

Turn off the water supply, dry the area, then run water and observe carefully. Common leak points include the P-trap joints, supply line connections, the faucet base, and the drain flange. Using a flashlight helps detect drips or moisture trails.

Can I fix a sink leak myself or should I call a plumber?

Many leaks (loose connections, replaced washers, re-sealing) are DIY-friendly if you have basic tools and patience. But if there is corrosion, cracked parts, complicated plumbing, or persistent leakage after your repair attempt, it’s safer to call a professional.

What materials or tools do I need to repair a kitchen sink leak?

Useful items include plumber’s tape (Teflon tape), silicone or plumber’s sealant, replacement washers or O-rings, wrench or adjustable pliers, bucket, rags, and possibly a new P-trap or parts if the existing ones are damaged.

How can I prevent future leaks at my kitchen sink?

Regular maintenance helps: periodically check and tighten connections, inspect washers/O-rings and replace when signs of wear appear, avoid overtightening, don’t pour grease or harsh chemicals down the drain, and clean drain traps to avoid buildup.
