FAQs About Kitchen Sink Drain Repair

What causes a kitchen sink trap to smell?

A dry or dirty P-trap allows sewer gases or decomposing food to cause foul odors. Cleaning or refilling the trap with water usually fixes this.

How often should I replace a kitchen sink trap?

On average, PVC kitchen sink traps last 7–10 years. Replace them sooner if they crack, leak, or corrode.

Can I repair a leaking sink trap myself?

Yes, most leaks are due to loose fittings or worn washers. Tighten connections or replace washers before considering a full trap replacement.

What’s the cost of kitchen sink drain pipe repair?

DIY repairs cost $20–$50 for parts. Hiring a professional may range from $150–$300 depending on complexity.

Is it safe to use chemical drain cleaners?

Avoid them, as harsh chemicals can damage pipes. Instead, clean traps manually or use a plumber’s snake.
