Septic Tank Odors? Here’s What’s Going On and How to Fix It

Septic Tank Odors? Here’s What’s Going On and How to Fix It

An odd sewage smell spreading around your house is never a good way to start or finish your day. It’s extremely unpleasant in addition to being risky to your overall health, as sewer odors are known to carry various microorganisms. It’s also never normal for sewer odors to find a way inside your house, so it obviously indicates that something needs to be fixed in your septic system. In fact, odors are one of the early ways to know when your septic tank needs attention, and calling a professional septic company in Atlanta would be the next right decision. So, let’s go over why you might be faced with this sign and some of the things you can do to fix it.

Harsh Chemicals

As you may already know, septic tanks work through small microorganisms that break down the waste. Sometimes, due to sending harsh chemicals down the drain, these bacteria die and the microbiome inside the tank is disrupted. So, when the waste can’t be broken down efficiently, naturally odors will form and will be noticed around the house.

Airflow Problems

To safely discharge gases of the septic tank into the atmosphere, your septic system uses vents. These vents can be commonly found on roofs, and in the event of snow, leaves, or birds that make a nest, these vents will be obstructed, and gases won’t be able to be discharged properly. As a result, you will face bad odors in your yards or drains.

Full Tank

Most of the time, the reason behind those bad odors is more simple than you think—the septic tank that hasn’t been cleaned for a while gets too full. When waste buildup gets to a point where the tank cannot handle it, it overwhelms the entire system; as a result, the tank will experience flow problems that can harm the drain field and sometimes backups. First, you’ll notice the increasing odors. Afterwards, the waste can appear in your drains. The solution to this specific issue is quite simple: you need to call professionals for septic tank pumping. If you have an unexplained sewer odor in your house and your system hasn’t been cleaned for a few years, this is the most likely reason.

Solutions

Now let’s go over some of the ways you can solve the odor issue.

  • As we mentioned before, an obstructed ventilation pipe can cause the bad odor. Inspect your roof carefully for any debris that might be blocking it.
  • Secondly, nothing should go down your toilet other than waste. Do not flush paper towels, sanitary wipes, baby wipes, cotton balls, or anything of the sort.
  • Thirdly, minimize the amount of chemicals you use when you’re cleaning your toilets and sinks. Maintaining your tank’s microbiome is absolutely essential.
  • Finally, never underestimate the importance of septic pumping. Regular septic cleaning is the main practice that will allow your septic system to work for many years to come.

Stopping Odors Before They Begin

Once again, we want to stress the importance of regular tank cleaning. Regular maintenance is the only way that you can have a healthy, odor-free septic system that doesn’t create a new problem every single day. Practice preventive measures and regularly call a professional for your septic systems’ needs, and you’ll be good to go.
