Septic System Troubleshooting: Identifying and Resolving Issues

Your septic system is a critical component of your home’s wastewater management. However, like any other part of your home, it can develop issues over time. Recognising the early signs of trouble and knowing how to troubleshoot can save you from costly repairs and ensure your system functions smoothly. In this article, we’ll explore common septic system problems and offer practical solutions for resolving them.

Common Signs of Septic System Problems

It’s important to recognise the early warning signs of septic system failure before the issue becomes severe. Some common indicators include:

• Slow Drains: If your sinks, showers, or toilets are draining more slowly than usual, it could be a sign that your septic system is backing up.
• Gurgling Sounds: Strange noises from your plumbing when flushing or running water could indicate a blockage in the septic system.
• Bad Odours: Foul smells coming from your drains, yard, or near the septic tank may suggest that the tank is full or the drain field is failing.
• Standing Water: If you notice pools of water or soggy areas near the drain field or septic tank, it may indicate a system overload or a broken pipe.
• Sewage Backups: This is one of the most serious signs of septic system failure, where untreated sewage comes back up through your drains.

Identifying these signs early can help you prevent a complete system breakdown.

Diagnosing the Root Cause

Once you’ve noticed an issue, the next step is diagnosing what’s causing it. Some of the most common causes of septic system problems include:

• Overloaded Tank: Septic tanks need regular pumping to remove solid waste. If your tank hasn’t been pumped in a long time, it may become overloaded, leading to backups.
• Clogged Pipes or Drains: Debris, grease, and other materials can cause blockages in the pipes leading to the septic tank or drain field.
• Damaged Drain Field: If the drain field is compacted or has absorbed too much water, it can’t process the wastewater efficiently, causing flooding or backups.
• Tree Roots: Tree roots can invade and damage septic system pipes, creating blockages or leaks.
• Chemical Overload: Excessive use of household chemicals can disrupt the bacterial balance in your septic tank, preventing it from breaking down waste effectively.

Solutions to Septic System Issues

Once you’ve identified the problem, it’s time to resolve it. Here are some troubleshooting solutions based on common septic issues:

• Regular Pumping: If your septic tank is full, the solution is simple—schedule a professional septic pumping service. It’s recommended to have your tank pumped every 3-5 years, depending on household size and usage.
• Clearing Blockages: For clogged drains or pipes, you may need to use a plumber’s snake or contact a professional to remove the blockage. Avoid using harsh chemicals, as they can damage the septic system.
• Drain Field Maintenance: If the drain field is saturated, try reducing water use in the home until the field can recover. In more severe cases, you may need to have a professional evaluate the condition of the drain field and make repairs.
• Root Removal: If tree roots are invading your septic system, you may need to have them professionally removed and install barriers to prevent further growth.
• Restoring Bacteria Balance: Avoid overloading your septic system with harsh chemicals. If needed, you can introduce bacterial additives to help restore the natural bacteria levels in the tank.

Preventative Maintenance

Preventing septic system issues in the first place is always the best approach. Here are some simple preventative measures you can take:

• Pump Regularly: As mentioned earlier, regular pumping is key to preventing overloads.
• Watch What You Flush: Only flush human waste and toilet paper. Avoid flushing wipes, feminine hygiene products, or paper towels, as they can cause blockages.
• Conserve Water: Reducing your household’s water use can prevent strain on the septic system.
• Avoid Harsh Chemicals: Use septic-safe cleaning products and avoid pouring harsh chemicals down the drain.
• Keep the Drain Field Clear: Avoid parking vehicles or placing heavy objects on the drain field, and be cautious with landscaping near the system.
