Have you ever heard strange gurgling noises coming from your sink, shower, or toilet? Those sounds are more than just annoying — they’re a sign that something’s wrong in your plumbing system. At Hudson Plumbing, we’ve helped countless homeowners track down the cause of pipe gurgling and fix it before it turns into a bigger (and more expensive) problem.
Why Do Pipes Gurgle?
Gurgling sounds in your pipes usually happen because air is trapped or water is draining incorrectly. Here are the main causes:
1. Blocked or Partially Clogged Drains
Food scraps, grease, soap scum, and hair can build up inside your drainpipes. As water tries to flow past these clogs, it creates bubbles and air pockets — that’s what you’re hearing as a gurgle.
2. Blocked Vent Pipes
Your home’s plumbing system has vent pipes that let sewer gases escape and keep water flowing smoothly. If these vents get blocked by debris, leaves, or even a bird’s nest, air can’t move properly. This causes slow draining and noisy pipes.
3. Sewer Line Problems
If the gurgling sound is coming from multiple drains, you may have a bigger issue — a blockage or break in your main sewer line. Tree roots, shifting soil, and years of buildup can damage sewer pipes and cause water to back up.
4. Old or Damaged Plumbing
Older drain systems are more likely to have buildup, corrosion, or outdated venting. Over time, these problems make it harder for water to flow, which leads to more trapped air and noise.
How to Fix Gurgling Pipes
If you hear a gurgling noise in just one sink or shower, you might be able to fix it yourself:
- Clear Minor Clogs – Use a plunger or a drain snake to remove debris. Avoid chemical drain cleaners, as they can damage your pipes.
- Check the Vent Pipe – If you can safely access your roof, check for visible blockages in your plumbing vent.
- Run Hot Water – For grease buildup, running hot water for several minutes can sometimes break it down.
However, if the gurgling sound is coming from multiple drains, happens often, or is paired with slow draining, foul smells, or water backups, it’s time to call a professional plumber.
