8 Warning Signs Your Small Old House May Have a Failing Septic System

A septic system is essential to any small old house not connected to a public sewage system. It helps to treat and dispose of wastewater from the household’s plumbing, making it safe for the environment.

However, like any other component of a house, a septic system can fail over time due to various reasons. It is crucial to be aware of the warning signs of a failing septic system and take necessary action before it becomes a significant problem.

Read on to learn some warning signs of a failing septic system of a small old house.

1. Gurgling Sounds

Gurgling sounds from your household plumbing can be a telltale sign of a distressed septic system. These noises, often heard after flushing the toilet or during the drainage of sinks and showers, signal a disruption in the flow within your system.

This suggests a clog in the septic tank or pipes. They are overfilled, so they stop wastewater from flowing.

Ignoring this sound warning can lead to worse septic failures. They need immediate attention to find and fix the problem.

Professional septic pumping services can help determine the cause of the gurgling sounds and provide appropriate solutions to ensure your septic system functions correctly. They may also recommend regular maintenance and inspections to prevent future problems.

2. Slow Drainage

Slow drainage in sinks, bathtubs, and toilets indicates that your septic system is not operating as it should. This symptom is often the result of a blockage or backup within the system, where solids have accumulated to the point that wastewater can no longer flow freely. It’s particularly concerning if multiple drains in the house are affected, as this suggests a systemic issue rather than a localized blockage in a single pipe.

When faced with slow drainage of a small old house, it’s vital to avoid common quick fixes like chemical drain cleaners, as these can further damage your septic system. Instead, consulting with a septic system professional can provide a safe, effective diagnosis and solution. An aging septic system may need to be replaced, but regular maintenance and proper usage can help extend its lifespan.

3. Foul Odors

Foul odors are a common warning sign of a failing septic system of a small old house. These unpleasant smells can manifest as sewage-like scents in and around the house, particularly near the septic tank or drainage field.

Foul odors can be caused by various issues within the septic system, from clogs and backups to leaks and cracks. It’s important not to ignore these smells as they can worsen over time and pose health hazards for you and your family. Professional septic services can help identify and address the root cause of these odors, whether it’s a simple repair or a more extensive septic system replacement.

4. Water Pooling

Another indication of a septic system failure in a small old house is water pooling in the yard, especially around the drain field area. This usually occurs when the septic system is overloaded and can no longer absorb and filter the wastewater effectively, causing it to rise to the surface. Not only does this create soggy patches in your garden, but it also poses a significant health risk by potentially exposing people and pets to untreated sewage.

Immediate action should be taken if you notice water pooling in your yard to prevent further damage to your property and the environment. Professional septic system services can assess the situation, determine the cause of the pooling, and suggest the best course of action, which might include repairing or replacing parts of the septic system or adjusting your household’s water usage to reduce strain on the system.

5. Bright Green, Spongy Grass

An unusually vibrant patch of grass over your septic drain field, significantly if it contrasts with the rest of your lawn, can indicate a failing septic system. This phenomenon occurs because the extra nutrients found in the wastewater act as a fertilizer for the grass above.

While it might seem like a positive outcome at first, it’s a sign that sewage is not properly breaking down and could be surfacing, which is a health hazard. This warning sign should not be ignored and warrants immediate attention from a septic system professional to assess the situation, identify any issues with the system, and provide appropriate solutions.

6. High Nitrate Levels in Well Water

Houses relying on well water should periodically test it for nitrate levels, as a failing septic system can lead to contamination. Elevated nitrate levels indicate that untreated sewage is seeping into the groundwater. This affects the household using the well and can also impact nearby water sources, posing a risk to the broader community.

Professional testing and septic system inspection are advisable to address this issue promptly. They can determine the cause of the contamination and provide solutions to protect your health and that of others. A professional plumber can install a filtration system to remove nitrates from your well water.

7. Backup of Sewage

One of the most alarming signs of a septic system failure is the sewage backup into your home. It can occur in the lowest drains first, such as a basement bathroom, and presents a significant health risk and a cleanup nightmare.

Sewage backup is a sign that your septic system needs immediate professional attention. It indicates severe blockages or a full septic tank that can no longer hold or process the household’s waste. A professional septic service can pump the tank and address any underlying issues to prevent future backups.

8. Age of the Septic System

The age of your septic system is a crucial factor to consider when monitoring its health. As with any other house component, septic systems have a lifespan and will eventually need to be replaced or upgraded. If your small old house has a septic system over 20 years old, you should have it inspected and maintained by a professional. This will help you avoid sudden failures.

Regular maintenance extends the septic system lifespan and prevents costly repairs. Even without apparent signs of failure, maintenance is crucial. Be mindful of what enters your septic system. Harsh chemicals or non-biodegradable items can harm it. This shortens its lifespan.

Taking Care of Your Small Old House

Knowing the warning signs of a failing septic system in your small old house is crucial to prevent costly repairs and protect your health. Remember, prevention is always better than cure for septic systems. So, pay attention to these signs and take prompt action to keep your septic system in good working condition.
