That telltale glug-glug sound in your bathroom is rarely a welcome discovery. Whether it’s coming from the shower, sink, or toilet, you can tell right away that it’s not normal. The question is, what is it and why is it in your house? Here are five reasons you may hear a gurgle in your bathroom plumbing.
- Plumbing Vent Blockage
Blockages in your plumbing vents can develop over time and cause these types of sounds. The vents are meant to (among other things) let air in so water can flow through the pipes at a steady rate without pressure problems. It’s similar to the pinhole on your coffee mug, which lets air in so that the hot coffee doesn’t come out in glugs and burn you.
If you know for sure that you haven’t heard the gurgling sound before, that means it’s a recent problem, which makes blockage a likely candidate. Since plumbing vents are typically located on the roof, it’s best to let a professional handle this problem.
