Gurgling drains are a pretty common occurrence in the home, and are usually met with mild neglect. Sure, it’s a bit annoying, but if a gurgling drain isn’t that much of a problem, right? Actually, a gurgling drain is usually a warning sign that it’s developing a clog. Let’s take a look at what causes that gurgling noise, and what you should do when you hear it.
Causes of Gurgling
When a clog begins to form in a water pipe it tends to have air pockets, created by the uneven nature of its formation. These air pockets remain trapped in the clog, until exposed to water. As water comes into contact with the clog, it releases the air as bubbles. These bubbles float back up through the water until they burst on the surface, creating that gurgling sound that you hear every time you pour water down the drain.
Now, the real question is: where is the clog actually located?
Possible Clog Locations
The most common kind of clog is located in the actual drainpipe. This can be caused by any number of things, depending on which drain is experiencing the gurgling. If it’s your sink, you may have bits of food debris stuck in the pipe. Shower and bathroom sink drains can often form clogs made by hair or toothpaste, respectively.
Another possibility is a blocked drain vent. Drain vents are responsible for the removal of sewer gas from the drainpipes in your home. These vents often lead up to the roof, where they can vent the gas outside the house and into the open air. Unfortunately, these vents are often a prime target for bird nests and other animal activity. If the vent becomes blocked, it can force gas back down and into the pipeline. If the gurgling in your drain is accompanied by a bad smell, it might be because of a blocked drain vent.
