Why Are My Drains Gurgling? (And What You Can Do About It)

Have you ever heard a strange gurgling sound coming from your sink tub or toilet? It might seem harmless but those noises are your plumbing’s way of crying out for help. At Excel Plumbing and Heating we’ve helped hundreds of Northern Minnesota homeowners solve gurgling drain issues and in many cases it’s a sign of something more serious.

Let’s break it down.

What Causes Gurgling Drains?

1. Blocked Vent Pipes: Your plumbing system breathes through vent stacks on the roof. When those get clogged with leaves snow or debris air can’t move freely and water struggles to drain. That’s when you hear the gurgling.
2. Partial Clogs in the Drain Line: Soap scum, grease, hair, or other substances can build up over time restricting flow. The trapped air has to escape somewhere often bubbling back through your sink or tub.
3. Improper Drain Slope: In older homes around Northern Minnesota we see a lot of drain piping that’s settled or wasn’t pitched correctly to begin with. Poor slope creates air pockets and gurgling sounds.
4. Septic System Issues: If your home uses a septic tank gurgling could mean it’s time for service. Backups or slow drain fields often show up first in your drain sounds.

What Should You Do?

• Listen to Which Fixture Is Making Noise
• Sink? Shower? Toilet? It can help narrow down the problem area.
• Check for Slow Draining
• If water pools up before draining you might have a clog forming.
• Avoid Using Chemicals
• Products like Drano can corrode your pipes. Instead, try an enzyme-based drain cleaner like Bio-Clean, which uses natural bacteria to eat away buildup in your pipes safely and effectively.
• Call a Pro
• If you’re unsure, it’s always best to have a licensed plumber diagnose the issue and recommend a long term fix.
