How To Check if Septic Tank is Full?

Maintaining a septic tank might not be the most glamorous task, but it’s crucial for homeowners living off the grid or in rural areas where municipal sewage systems are not available. A septic tank that’s full or nearing capacity can lead to costly and unsanitary problems, so knowing how to check its status is essential. In this article, we’ll guide you through the steps to determine whether your septic tank is full, enabling you to take proactive measures to ensure the smooth functioning of your wastewater disposal system and prevent any unpleasant surprises down the line. So, how do you check if a septic tank is full?

The simplest way to check if a septic tank is full is by acknowledging signs such as tank overflowing, toilets taking longer to flush or odours from the tank. You can check the precise level by opening the inspection lid, but it’s recommended to leave this to professionals due to potential dangers.

With this being said, there are many ways to know if your septic tank is full without needing to open the inspection lid. Having a full septic tank can lead to expensive repairs and the discomfort of foul odours, so it is crucial to know when a septic tank is full.

Ways To Check if Your Septic Tank is Full

Inspecting and knowing the level at which your septic tank is sitting, is more important than most homeowners with these systems think. From saving money, ensuring safety and preventing serious plumbing issues; it is definitely worth your time to check your septic tank now and then. Here are the various ways in how you can check if your septic tank is full:

Check The Level Float via The Inspection Pipe

Checking the level float via the inspection pipe is the most accurate method in monitoring the status of your septic tank. The inspection pipe is typically a small, vertical pipe that extends from the top of your septic tank to the surface of the ground, designed for easy access and often equipped with a removable cap. To inspect the level float, remove the cap carefully, as gases and odours may escape. Use a flashlight to illuminate the interior of the pipe, where you can observe the position of the level float. If it’s near the top, it may indicate that the tank is approaching full capacity, while a position near the bottom suggests the tank is in good shape. It’s advisable to check the level float periodically, perhaps every few months, to track changes in the liquid level. Any significant deviations may signal the need for maintenance or pumping. Regularly checking the level float through the inspection pipe allows you to gain valuable insights into your septic tank’s condition and take proactive measures to prevent potential issues before they become costly problems.

It is not recommended for homeowners without the correct knowledge or equipment to open the inspection lid, as it has potential dangers by doing so. The best solution would be to get an expert to inspect the septic tank.

Check The Speed of Drainage and Flushing

Checking the speed of drainage and flushing is another vital aspect of maintenance to ensure your septic tank isn’t full and is functioning optimally. 

Begin by monitoring the drains and toilets in your home. Pay attention to how quickly water drains from sinks, showers, and bathtubs, as well as how efficiently toilets flush. Slow drainage and sluggish flushing can be indicators of potential septic system issues.

Next, run some water into multiple fixtures simultaneously. For example, flush a toilet while running a sink faucet or taking a shower. If you notice that the water backs up or drains slowly in one fixture when another is in use, it may suggest a problem within the septic system, such as a clog or a full tank.

Additionally, keep an eye on gurgling sounds in the drains or toilets when water is running or being used. These noises can signal air bubbles or pressure changes within the plumbing, possibly indicating septic system trouble.

If you observe any of these signs of slow drainage or flushing, it’s advisable to consult a professional septic service provider promptly. They can perform a thorough inspection, empty the septic tank, identify the underlying issues, and recommend the necessary repairs or maintenance to keep your septic system functioning smoothly. Regularly checking the speed of drainage and flushing can help you catch problems early, preventing more extensive and costly issues down the line.

Check for Nasty Odours

Checking for foul odours around the location of your septic tank is a straightforward yet crucial step in septic system maintenance. Unpleasant odours can be an early warning sign of potential problems within your septic system. 

Start by taking a walk around your property, paying close attention to the area where your septic tank is located. The tank is typically buried underground, so focus on the ground surface above it.

If you detect any strong, persistent, or foul odours resembling sewage, rotting eggs, or a musty smell, it could indicate a problem with your septic system. These odours may result from a leak, blockage, or the septic tank being too full.

Check the ground for any wet or soggy areas, especially near the septic tank or the drain field. These wet patches can be a sign of a septic system malfunction, and the accompanying odours can be a confirmation.

Odours from a septic system should not be ignored, as they may indicate potential health risks and environmental concerns. If you notice foul odours around your septic tank, it’s essential to contact a professional septic service provider promptly. They can investigate the issue, identify the source of the odour, and recommend the necessary repairs or maintenance to ensure your septic system operates safely and efficiently. Addressing odour concerns promptly can help prevent more significant problems and costly repairs in the future.

Check for Unusual Grass Growth Around the Septic Tank

Checking for unusual grass growth around the septic tank area is yet another simple yet effective way to gauge the current level of waste within your septic system. Pay attention to the vegetation around the vicinity of the tank and drain field. If you notice excessively lush or discoloured patches of grass, it could be a sign of septic system issues.

Healthy grass typically thrives in the nutrient-rich environment provided by a well-functioning septic system. However, if the system is compromised and leaking, it can introduce excess moisture and nutrients into the soil, causing abnormal grass growth.

Patches of dead or brown grass may also indicate problems, as they might result from soil compaction or damage caused by heavy septic equipment. Monitoring your lawn’s condition can help you identify potential septic system concerns early, prompting timely maintenance or repairs to prevent further damage and ensure the longevity of your system.

How Often Should You Check If Your Septic Tank Is Full?

How often you should check if your septic tank is full depends on several factors, such as the size of your household, your water consumption habits, and the tank’s capacity. In general, it is recommended to schedule a professional inspection and potential pumping every 3 to 5 years. However, you should use the methods mentioned in this article to check every 6-12 months. 

Nevertheless, certain situations may necessitate more frequent assessments. For instance, if your household is large or frequently accommodates guests, your septic tank may reach capacity more rapidly, prompting a need for more frequent checks. 

Ultimately, the key is to maintain a proactive approach to septic system care, adjusting the inspection frequency as needed to ensure the system’s efficiency and longevity. Consulting with a professional can help determine the most appropriate inspection schedule for your specific circumstances.
