1. Lack of Consistent Maintenance

One of the mot overlooked reasons a septic tank causes is problems is simply because people fail to keep up the regular maintenance. After all, the septic tank is out of sight out of mind for most people, and it’s only when something goes wrong that you notice it.

You can easily avoid this by regular inspections and getting your tank pumped every 3-5 years. Because if you don’t maintain it, solids will build up in the tank, causing backups and potentially damaging the system.

Fortunately, though, there are products on the market that can help keep your septic tank maintained for longer.

2. Clogging and Blockages

Secondly, it may be caused by clogs and blockages. Clogs happen when things like wipes, diapers, or feminine hygiene products get flushed. Oftentimes, these will block the pipes and mess up the flow of wastewater. In fact, even using too much toilet paper can cause issues. So make sure everyone in your home knows what they should and shouldn’t flush.

If you think your septic tank has clogs or blockages, then you NEED to try Septifix!

3. Tree Root Infiltration

Now this one doesn’t affect everyone BUT tree roots can grow into your septic tank pipes, leading to blockages and damage. If you’re going to plant trees it’s best to plant them as far away from your septic tank as possible. Because if they do get into your system, the damage will often lead to expensive repairs.

4. Excessive Water Use

A septic system can only handle so much water at once. Using too much water, such as doing multiple loads of laundry in one day or having leaky fixtures, can overload the system. Then the tank won’t treat the waste properly, which causes backups and overflows.

5. Chemical Damage

And using harsh chemicals and cleaners can really mess up your septic tank. These strong cleaners kill the beneficial bacteria that break down waste. So, try to avoid using bleach, antibacterial soaps, and especially heavy-duty drain cleaners. Instead, go for septic-safe products to keep the bacteria in balance and your system running smoothly.

But if you HAVE to use these products, Septifix is a great way to make sure that the bacteria in your septic tank stay healthy and thrive.

6. Improper Installation

Getting your septic system installed correctly is a big deal. If it’s done wrong, you could face all sorts of problems like poor drainage or even total system failure. Make sure you hire a qualified professional to handle the installation. Proper design and setup are key to making sure your system lasts and works well.

And if you haven’t, get a professional out as soon as possible. Small fixes now, can prevent big problems later.

7. Soil Absorption Issues

The soil around your drain field needs to be just right to absorb wastewater properly. If the soil is too heavy, like clay, or if the water table is high, wastewater can end up pooling on the surface. Normally, a percolation test will be conducted before installing your system to ensure the soil can absorb water effectively.

8. Tank and Pipe Cracks

Septic tanks and pipes can crack over time due to age, shifting soil, or heavy loads above ground. These cracks can let untreated waste leak into the surrounding soil, which is a big environmental hazard. Regular inspections can help catch and fix these cracks before they turn into serious problems.

9. System Overload

Having a big party or a lot of guests over can put a strain on your septic system. More people mean more water usage and waste. To keep things running smoothly, try to stagger water usage and let your guests know about what they should and shouldn’t do with the septic system.

10. Biological Overload

Your septic system relies on bacteria to break down waste. If you dump too much waste in at once, like from a garbage disposal, it can overwhelm the bacteria. Instead, try composting food waste and using the garbage disposal sparingly to keep everything balanced.

Fortunately Septifix was designed to feed the beneficial bacteria in your tank and make sure they’re getting optimal amounts of oxygen!

11. Ground Movement

Sometimes, the ground moves naturally or because of construction, which can cause pipes to disconnect or crack. This leads to leaks and inefficiency in your septic system. Keep an eye on things and make sure no heavy machinery is used near the septic area to prevent this.

12. Damage from Tree or Plant Roots

Tree roots are a common problem, but roots from other plants can also invade and damage your septic system. Installing a root barrier and keeping plants at a safe distance can help avoid these issues.

13. A Collapsed Baffle

Baffles are super important because they direct the flow of wastewater in your septic tank. If a baffle collapses, it can cause solids to clog the inlet or outlet pipes. Regular inspections can catch early signs of baffle damage, so you can fix it before it becomes a big problem.

14. Damaged Dip Pipe

The dip pipe is there to help keep solids separate from liquids in the tank. If it gets damaged, solids can end up in the drain field, leading to blockages and possibly system failure. Regular inspections and repairs are key to making sure your dip pipe stays in good shape.

15. Vehicle Damage

Parking or driving heavy vehicles over your septic tank or drain field can crush the pipes and compact the soil, which messes up proper drainage. It’s a good idea to clearly mark these areas and keep vehicles away to prevent accidental damage.

16. Hydrostatic Pressure

High groundwater levels can create hydrostatic pressure, pushing water into your septic tank and causing flooding and malfunctions. Installing proper drainage around the tank and using watertight tank covers can help manage this pressure and keep your system running smoothly.

17. Aging Tank

Older septic tanks are more prone to cracks, leaks, and structural failures. If your tank is several decades old, consider having it inspected more frequently and plan for a potential replacement to avoid unexpected failures.

18. Change to Ground Conditions

Changes in the surrounding environment, such as new construction, landscaping, or natural events, can affect your septic system’s performance. Regularly assess the impact of these changes and consult with professionals to mitigate any adverse effects.
