One major issue that homeowners may encounter with their septic tanks is when it becomes full. Knowing how to tell if your septic tank is full is crucial in order to prevent any backups, sewage leaks, or costly repairs. In this blog post, we will explore the signs that indicate a full septic tank and what you can do to address the issue.

1. Slow Draining Fixtures

One of the most common signs that your septic tank is full is slow-draining fixtures. This can include sinks, showers, toilets, and even washing machines. If you notice that water is taking longer than usual to drain or if you experience frequent backups, it may be a sign that your septic tank has reached its capacity. This occurs because the excess wastewater has nowhere to go and will start to accumulate in your plumbing fixtures.

2. Unpleasant Odors

Foul odors in and around your home can also indicate a full septic tank. When a septic tank becomes full, the sewage and other waste materials begin to release gases, resulting in a distinct and unpleasant smell. If you notice a persistent odor of sewage near your drains, toilets, or even in your yard, it is important to address the issue promptly before it worsens.

3. Lush Grass or Standing Water in the Yard

A full septic tank can cause water to build up in your yard, leading to areas of standing water. This occurs when the excess wastewater from the tank seeps into the surrounding soil, saturating it and preventing proper drainage. As a result, your yard may have areas of unusually green and lush grass or puddles of water even when it hasn’t rained. These signs are clear indicators that your septic tank is full and may require immediate attention.

4. Gurgling Noises in Plumbing

If you hear gurgling or bubbling sounds coming from your drains or toilets, it could be a sign of a full septic tank. When the tank is full, the excess waste can cause air bubbles to form in the plumbing system, resulting in these unusual noises. It’s essential to address this issue promptly to prevent any further damage to your plumbing or septic system.

5. Sewage Backup in Fixtures

Perhaps the most obvious sign of a full septic tank is a sewage backup in your fixtures. If wastewater begins to back up into your sinks, showers, or toilets, it is a clear indication that your septic tank is at capacity. This can be a messy and unpleasant situation that requires immediate action to prevent further damage to your home and health hazards.

What to Do if Your Septic Tank is Full

If you suspect that your septic tank is full, it is essential to take prompt action to address the issue. Here’s what you can do:

1. Schedule a Professional Inspection: Contact a licensed septic tank professional to conduct an inspection and assess the situation. They can identify any issues with your septic system and determine if the tank needs to be pumped.

2. Pump and Clean the Tank: If the inspection confirms that your septic tank is full, it will need to be pumped and cleaned. A professional service can safely remove the accumulated waste and ensure that your tank is functioning properly.

3. Maintain Regular Pumping Schedule: To avoid future problems, it is important to establish a regular pumping schedule for your septic tank. The frequency at which your tank needs to be pumped will depend on factors such as the size of the tank and the number of occupants in your home. A professional can help you determine the appropriate pumping schedule for your specific situation.

4. Practice Proper Septic System Maintenance: Regular maintenance is key to preventing septic tank issues. Avoid flushing non-biodegradable items down the toilet, such as wipes and hygiene products, as they can clog your system. Additionally, be mindful of the chemicals you use in your household, as some can be harmful to your septic tank’s bacteria.


Knowing how to tell if your septic tank is full is crucial for homeowners. By paying attention to the signs like slow-draining fixtures, unpleasant odors, standing water in the yard, gurgling noises, and sewage backups, you can take prompt action to address the issue and prevent costly repairs. Regular inspections, pumping, and proper maintenance are essential for the longevity and proper functioning of your septic system. Don’t ignore the signs – take care of your septic tank to ensure a clean and healthy home.
