Slow Drains Throughout the House: Is It Septic?

A slow drain in the kitchen or the bathroom may seem like an isolated problem. However, multiple slow drains throughout your home suggest a bigger underlying problem that requires professional attention. While many homeowners often turn to plungers, augers, and cleaners for help, these DIY methods only provide temporary relief. At Septic Blue of Charlotte, we leverage extensive expertise and knowledge to inspect, diagnose, and address the root cause, ensuring smooth-flowing drains and a reliable septic system for years. If you notice these signs in your home or business, call a reputable septic company quickly to get ahead of underlying issues.

How Your Septic System Works

Before you can address slow drains, understanding how your wastewater system works is crucial. Wastewater from your home collects in the tank for separation, forming three layers: sludge at the bottom, scum on top, and wastewater in the middle. Over time, waste can build up in the tank, prompting professional septic pumping and cleaning to mitigate messy surprises and costly damage.

The liquid waste in the tank flows into the drain or leach field for further filtration before it is released into the soil. If something is amiss in this process, early intervention is key to protecting your home, family, and the environment.

Common Causes of Slow Drains

Now that you know how your septic system works, you can provide better care and make the most of your system. Let’s delve into the common septic-related causes of drainage issues you should keep an eye out for.

A Full or Overloaded Septic Tank

As mentioned, waste in the tank can accumulate over time, obstructing water flow. If your last septic pumping session was over three years ago, it may be time to call a professional technician for an inspection. Septic service providers can measure sludge and scum levels, pinpoint buildup within the system, and recommend effective solutions to improve system efficiency and safety year-round.

A Clogged or Failing Drain Field

The drain field is considered the most important component in wastewater treatment. If solid waste in the tank escapes into the drain field, it can cause wastewater to flow out the wrong way, leading to backups into your home and puddles in the yard. By prioritizing routine septic cleaning by a professional, you can maintain a system that operates optimally.

Blocked or Damaged Pipes

Trees provide many benefits to your landscape and the environment. However, their vast root systems intertwine with septic lines and grow inside through cracks. If left unattended, roots can cause full blockage, causing slow drains and backups. Before using drain cleaners or plunging for the tenth time this week, call a septic service provider to inspect your system and determine whether hydro-jetting or pumping is needed.

Bacterial Imbalance in the Tank

Septic systems rely on beneficial bacteria to break down waste. Despite the toxic environment in the tank, regularly using harsh chemicals, bleach, and antibacterial soap can disrupt this balance. If the conditions in the tank are not conducive to these microorganisms, it can lead to buildup in the tank and drainage issues.
