A gurgling noise coming from the drains in your home typically points to an issue with your septic system, which can have major implications if not adequately addressed. There are a number of reasons why your drains might be gurgling, including some that are simple fixes and those that require a professional’s help. Here’s a closer look at what may be happening.

Why Do Septic Tanks Gurgle?

1. Drain or Pipe Clogs

When clogs occur in the drains in your home, water flowing around them often makes a gurgling noise. The same noise may be present when the clog is located deeper down in the pipes of your plumbing system. The solution to a clog usually begins with a plumber, though a septic specialist may be required, depending on where the problem is located. When it comes to septic pipes, tree roots can sometimes infiltrate them in search of moisture.

You can prevent drain clogs by only flushing the proper items down your toilet. Things like “flushable” wipes, kitty litter, and paper products other than toilet paper can easily block drains. Prevent future root infiltration by planting trees as many feet away as the tree will grow when reaching full maturity. 

2. Full Septic Tank

Septic tanks require pumping at least every three to five years depending on their size and how much they’re used. If a tank becomes too full, waste can back up into pipes, eventually making its way back into plumbing fixtures within the home, producing a telltale gurgle as it does so. 

Regular maintenance of your tank is crucial in this case. In addition to being pumped, your septic system should also be routinely inspected. This includes the tank itself as well as your drain field, which is integral in filtering wastewater before it’s redeposited cleanly into the ground. 

3. Drain Vent Problems

Vents within your drains are essential for releasing sewer gases from your system to prevent buildup. When the vent is obstructed, you’ll usually hear gurgling in the bathtub or sink drains when you flush the toilet. The noise you hear is caused by air passing through water as it flows through the drain vent. 

Clearing drain vents is not as easy as something like plunging a clogged toilet or sink. When a block forms, you may need a plumber to address the issue, especially if the roof drain is affected. You can also include vent clearing into your maintenance plan to prevent clogs before they occur.
