Why does my drain gurgle?
June 23, 2015

Have you noticed a "blub-blub" or "glug-glug" sound coming from your drain?

The problem is most likely a partial clog in the drainpipe.

While a partial clog can lead to serious blockage-causing flooding and smelly sewage backup- it's relatively simple to fix.

But before making one of these drain-clearing mistakes, let us explain partial clogs (and that noise) in more detail...

Why the gurgling?

Basically, when something is obstructing the flow of water inside your drainpipe, it causes the water to drain slower than usual. This creates air bubbles inside the main drain and that's the gurgle you hear.

What causes a partial clog?

There are a number of things that cause a blockage inside your plumbing system: hair, dirt, food, and soap particles are a few of many.

How to detect a partial clog vs. a bigger issue

If you want to do some drain-noise detective work, before calling a professional to properly diagnose and fix the issue, here are a few clues that help indicate a partial clog.

Identify the fixture

If the sound occurs only at a specific fixture (such as a kitchen or bathroom sink, tub or in more extreme cases a toilet), it's very likely the blockage is local to that area and its drain piping.

Use your senses

Make sure there isn't a noticeable sewage stench coming from your drains. Also flush a toilet and look for any major backup.

What now?

If you suspect the clog is minor and you know what you're doing, you could try removing the clog using a plunger the right way. If a good plunge does the trick, nice job!

If this does not fix the problem, you probably have a heavy clog that requires the knowledge and tools of a trusted plumbing professional.

Important warning: Do NOT pour commercial drain cleaners down your drain--these chemicals contain toxic fumes and can seriously damage your pipes. Plus they usually only remove enough of the clog to get your drain running--and then clog again later.
