The Gross Truth About What’s Hiding in a Full Septic Tank
Most homeowners don’t care about what happens to a septic system until there is a problem. However, by then, the septic system is already full and harming itself. In this article, we will go over a breakdown of what’s inside a septic tank and some signs that your septic system is full. If you want to learn more, call Rooter Septic Services today.
A Breakdown of What’s Inside a Septic Tank
- Solid Waste: When wastewater enters the septic tank, the solid waste settles at the bottom of the tank due to its density. This is also called a sludge layer, which is composed of undigested solids and other waste that can’t float due to their weight. The bacteria inside the tank play a crucial role in breaking down these solid wastes and ensuring that they won’t build up too much over time.
- Scum Layers: The scum layer is at the top of the septic tank. It is made of fats, oils, and grease. This layer acts like a film that can trap the gases and harm the system. When you pour cooking oil and other fats down the sink, you just contribute to the scum layer, which harms your septic system.
- Bacteria and Microbes: There are billions and billions of bacteria and microbes that work together to digest waste. They turn normal solids into liquids and gases and play a crucial role in the processing of wastewater. Killing these microbes also means just ending the life in the tank and shortening its lifespan.
- The Toxic Gases: When bacteria and microbes digest organic matter, they release gases that float to the top of the tank.
Signs Your Septic System Is Full
- Slow Draining Sinks & Bathtubs: One of the first signs of a full septic system is the slow draining of sinks and bathtubs. If you notice a single slow drain, it might be because of a clog. However, seeing multiple suggests that your septic system may need attention. Slow drains often happen as a result of the solid waste buildup at the bottom of the tank, which blocks the normal wastewater flow. If you experience this, call Rooter Septic Services to schedule for a septic cleaning right away.
- Gurgling Sounds From Pipes: Your plumbing system can make strange gurgling noises. These noises are often created when there is air trapped in your pipes, which shows your tank doesn’t deal well with incoming wastewater. You may notice these gurgling noises, especially in plumbing fixtures like showers and toilets.
- Unusual Odors From The Property: A clear warning sign that your septic system is full is when there are bad smells around your property. The gases, like carbon dioxide, hydrogen sulfide, and methane from the waste, create unpleasant odors, which need immediate attention. These smells can indicate a system failure and have to be looked at by a professional septic company. If you want to learn more, call Rooter Septic Services today.
