July 7, 2023

Maintaining a properly functioning septic system is crucial for the smooth operation of your home's wastewater disposal. However, over time, clogs and blockages can occur, leading to potential issues and inconveniences. In this comprehensive guide, we'll walk you through the process of safely unclogging your septic system. 


The Environmental Protection Agency (EPA) also recommends getting your septic tank pumped every two to five years, depending on the capacity of the tank and the demands of your household. You want to pump your tank before it is full to avoid unnecessary problems.(1)


Whether you're experiencing slow drains, gurgling sounds, or foul odors, these steps can help you address the problem effectively. So, let's dive in and learn how to safely unclog your septic system.

Understand the Signs of a Clogged Septic System

Before attempting to unclog your septic system, it's important to identify the signs of a blockage. Slow draining sinks, toilets, or showers, gurgling sounds in the plumbing, and unpleasant odors are common indications of a clogged septic system. If you notice any of these signs, it's time to take action.

Exercise Caution

Working with a septic system requires caution and adherence to safety measures. Avoid direct contact with wastewater and wear protective gear such as gloves and goggles. If the problem seems extensive or beyond your comfort level, it's best to seek professional assistance from septic tank pumping companies in the Chattanooga area.

Locate the Septic Tank

To effectively unclog your septic system, you need to locate the septic tank. The tank is typically buried underground and can be found by referring to your property's septic system diagram or by contacting a septic system professional.

Pump the Septic Tank

Regular septic tank pumping is essential for maintaining a healthy system. If you haven't had your septic tank pumped recently, it's recommended to schedule septic tank pumping in Chattanooga. Regular pumping helps prevent clogs and ensures the system operates smoothly.

Use a Plunger

For minor clogs, a plunger can be a handy tool. Apply a plunger to the affected drain, creating a tight seal, and vigorously plunge up and down. This action can dislodge smaller blockages and restore proper flow.

Avoid Chemical Drain Cleaners

Chemical drain cleaners may seem like a quick fix, but they can harm your septic system's delicate balance of beneficial bacteria. Avoid using chemical drain cleaners as they can potentially worsen the problem and cause damage to your septic system.

Utilize a Plumbing Snake

A plumbing snake, also known as an auger, can be effective in breaking up stubborn clogs. Insert the snake into the drain or cleanout opening and rotate it gently. The snake will help break apart and remove the blockage, allowing wastewater to flow freely.

Consider a Hydro Jetting Service

In more severe cases of clogs or stubborn blockages, professional hydro jetting may be required. Hydro jetting involves using high-pressure water to clear the pipes and remove accumulated debris. Contact a reputable septic tank pumping company in Chattanooga, TN, that offers hydro jetting services for a thorough cleaning.

Implement Preventative Measures

To prevent future clogs, it's essential to adopt preventative measures. Avoid flushing non-biodegradable items, such as wipes, sanitary products, or paper towels, down the toilet. Be mindful of what you dispose of in sinks and drains as well. Additionally, consider using bacteria additives that promote the breakdown of waste in your septic system.

Practice Water Conservation

Excessive water usage can overload your septic system, contributing to clogs and potential issues. Practice water conservation by fixing leaks promptly, installing water-saving fixtures, and being mindful of water usage habits. Conserving water helps alleviate stress on your septic system.

Regular Inspections

Schedule regular inspections ofyour septic system to catch any potential issues before they escalate. Professional inspections can identify early signs of clogs or other problems and allow for prompt intervention.

Maintain Drain Field Health

The drain field is a crucial component of your septic system. To maintain its health, avoid parking vehicles or placing heavy objects on the drain field area. This can compact the soil and hinder proper drainage.

Address Tree Roots

Tree roots can infiltrate septic system pipes, causing clogs and damage. If you suspect tree roots are causing issues, consult a professional to assess the situation and provide appropriate solutions.

Install Filters

Installing filters in your drains can help trap solids and prevent them from entering your septic system. These filters are especially useful in preventing larger particles from clogging the pipes.

Know the Limitations

While you can address minor clogs and perform routine maintenance, it's crucial to recognize the limitations of your expertise. For major clogs, extensive repairs, or if you're unsure about the proper course of action, it's best to contact professional septic tank pumping companies in Chattanooga.

Avoid Excessive Use of Antibacterial Products

Excessive use of antibacterial products can disrupt the natural balance of bacteria in your septic system. While it's important to maintain hygiene, it's equally essential to use these products judiciously to preserve the health of your septic system.

Educate Household Members

Ensure that everyone in your household is aware of the dos and don'ts when it comes to septic system usage. Educate them about proper waste disposal, avoiding excessive water usage, and recognizing signs of potential issues.

Know the Cost of Pumping

Understanding the cost of pumping a septic tank in Chattanooga, TN, is important for budgeting and planning. Contact reputable septic tank pumping companies to inquire about their pricing and schedule routine pumping as recommended.

Consult with Experts

If you encounter persistent clogs or recurring issues with your septic system, don't hesitate to consult with experts. Professional septic tank pumping companies have the knowledge and experience to diagnose and address complex septic system problems.

Prioritize Regular Maintenance

Regular maintenance, including septic tank pumping and inspections, is key to preventing clogs and maintaining the longevity of your septic system. Establish a maintenance schedule and adhere to it to ensure the optimal functioning of your system.


In summary, properly maintaining and unclogging your septic system is essential for the efficient operation of your wastewater disposal. By understanding the signs of a clogged system and following the steps outlined in this guide, you can safely address clogs and prevent future issues.
