Why Are There Bubbles in My Sink?
What are the bubbles in my sink?
Are you hearing a strange gurgling sound coming from your sink? Bubbles in your sink and strange sounds can be a sign of trouble with your plumbing.
Here’s why you might see bubbles or hear gurgling in your sink — and what you can do to fix this common plumbing problem.
Why are bubbles coming from my drain?
If you see bubbles or hear gurgling noises coming from your drain, it means that there is air trapped inside. While air is a natural part of your plumbing, it becomes a problem when pressure builds and affects the seal in your sink’s P-trap (forming bubbles). If there is pressure in your drain, when water flows down the drain, a vacuum will pull air through the P-trap, causing gurgling noises and bubbles.
Why is there pressure building in my sink drain?
There are a few different reasons why pressure could be building in your sink drain:
- Your drain is clogged. A drain that is clogged in your bathroom or kitchen can cause pressure buildup, gurgling, and bubbles to come up through your sink drain.
- The P-Trap is not installed correctly. If the vent is not installed the correct distance from the P-trap, you could get this gurgling sound developing.
- Your drain vents are blocked. When the main vents are clogged, flushing a toilet or draining a tub can cause your sink to gurgle.
