As a homeowner, it’s important to stay on top of the maintenance and upkeep of all the systems that keep your home running smoothly. One such system, often overlooked, is the septic tank.
While it may be out of sight and out of mind for much of the year, regular maintenance and care are essential for ensuring that your septic system continues to function properly. This prevents costly repairs and potential environmental hazards.
In this guide, we’ll break down everything homeowners need to know about septic tank service. Read on.
What is a Septic Tank?
A septic tank is an underground wastewater treatment system commonly used in rural or suburban areas where a municipal sewer system is unavailable. The septic system works by using a tank to treat and process waste from the home, including water from:
- toilets
- sinks
- showers
- laundry
The system typically includes:
The Septic Tank
This is a large, watertight container buried underground. It holds wastewater for a period of time, allowing solids to settle at the bottom while the liquid effluent rises to the top.
The Drain Field (Leach Field)
This is the area where the liquid effluent is filtered through soil and bacteria. This helps further break down any remaining impurities before the water returns to the groundwater supply.
Understanding the components and function of your septic system is important for proper maintenance.
How Does a Septic Tank Work?
In a septic tank, waste from your home enters the tank, where the process of separating solids, liquids, and gases begins. Here’s a breakdown of the process:
Solid Waste
Heavy solids (like food particles, toilet paper, and waste) sink to the bottom of the tank. Over time, these solids break down into sludge, aided by bacteria inside the tank.
Liquid Effluent
Lighter waste, including oils, grease, and wastewater, rises to the top and is sent to the drain field where it’s filtered through the soil and eventually returned to the groundwater.
Gases
Some gases, including methane, are produced as waste decomposes, and these gases exit the tank through a vent system. The efficiency of your septic tank depends on the balance of solids, liquids, and gases. Without proper maintenance, the tank can become overloaded, leading to blockages or even system failure.
Common Septic Tank Problems
Septic tanks are generally reliable when well-maintained, but like any system, they can experience issues from time to time. Here are some of the most common problems:
Clogs or Blockages
A common issue with septic systems is clogging, which often happens in the pipes that lead to and from the tank. Blockages can be caused by things like flushing inappropriate items (e.g., wipes, paper towels, or non-degradable products), grease buildup, or tree roots intruding into the system.
Overflow and Backup
When a septic tank fills up with sludge and the solids can’t settle properly, the waste begins to overflow into your pipes and drains. This can lead to unpleasant smells, sewage backups, and even the potential contamination of your yard or water supply.
System Leaks
Cracks or leaks in the septic tank itself or in the pipes leading to the drain field can allow wastewater to leak into the surrounding soil, creating unhealthy conditions and potentially polluting groundwater. These leaks can be caused by natural wear and tear, poor installation, or damage from heavy machinery or vehicles above ground.
Soil Compaction or Drain Field Problems
If your drain field becomes compacted or clogged, it won’t be able to properly filter wastewater. This often happens when the system is overburdened or if there’s excessive water usage. Improper maintenance, like parking over the drain field or planting deep-rooted trees nearby, can also lead to drain field issues.
Bacterial Imbalance
The bacteria in your septic tank are crucial for breaking down waste. If these bacteria are killed off by harsh chemicals or cleaning products, it can disrupt the entire system, leading to clogs, backups, and inefficient waste treatment.
Signs That Your Septic Tank Needs Service
The best way to prevent septic tank issues is to spot early warning signs. If you notice any of the following symptoms, it may be time to schedule a service visit:
Slow Drains
If drains in your kitchen, bathroom, or laundry room are sluggish, it may indicate that your septic system is backing up.
Foul Odors
Unpleasant odors around your drains, in your yard, or near the septic tank area could signal that the tank is full or failing to process waste effectively.
Pooling Water or Lush Grass
If you notice standing water or unusually green, wet patches in your yard near the septic tank or drain field, it could indicate that the system is overflowing or has a clog.
Backups in Toilets or Drains
If your toilets or sinks begin to back up, it’s a major red flag that your septic tank is in need of attention.
Unusual Sounds
Gurgling sounds from your plumbing system often indicate air or water pressure issues within the pipes, possibly stemming from a septic system problem. If any of these signs are present, it’s critical to call a professional as soon as possible to avoid further damage and expensive repairs.
Regular Septic Tank Maintenance: What Homeowners Should Do
Proper maintenance is key to extending the life of your septic system and avoiding major problems. Here are some essential maintenance tasks every homeowner should follow:
Pump the Tank Regularly
The most important part of septic tank maintenance is regular pumping. Over time, solids and sludge accumulate in the tank, which can cause blockages and prevent proper function. Experts recommend pumping the tank every 3 to 5 years, though the frequency can vary based on the size of your tank, the number of people in your household, and the overall health of the system.
Inspect the System Annually
Even if you don’t need to pump your tank every year, it’s wise to schedule an annual inspection with a professional. During the inspection, a technician can check for potential issues, including leaks, cracks, or damaged components, and address them before they turn into larger problems.
Conserve Water
Excessive water usage can overwhelm your septic system. Be mindful of water waste by fixing leaks promptly, taking shorter showers, and running dishwashers and washing machines only with full loads. You can also install water-saving fixtures like low-flow toilets and showerheads.
Use Septic-Safe Products
Many cleaning products, soaps, and personal care items contain harsh chemicals that can harm the bacteria inside your septic system. Use septic-safe cleaners and avoid pouring chemicals or grease down the drain.
Carefully Manage Your Drain Field
The drain field is a crucial part of the system’s filtration process. Avoid parking vehicles or placing heavy objects on top of the field, as this can compact the soil and impair the drainage process. Additionally, plant only grass or shallow-rooted plants above the field to prevent root intrusion into the pipes.
When to Call a Professional
While regular maintenance can prevent many issues, there are times when a professional septic tank service is necessary. Here are a few situations where you should call an expert:
System Failures or Overflows
If you experience backup, foul odors, or unusual wetness around the septic area, it’s essential to call a technician right away to assess the problem and prevent further damage.
Unexplained Changes in Performance
If you notice any changes in the system’s performance, such as slow draining or unusually high water usage, a professional can help diagnose the problem.
Repairs or Replacements
If your septic system requires major repairs, such as replacing the tank or drain field, you’ll need a professional with the proper equipment and expertise to handle the job.
Choosing a Qualified Septic Service Provider
When it comes to septic tank maintenance and repairs, choosing the right professional is crucial. Here’s how to find a reliable septic service provider:
Look for Certifications and Experience
Ensure that the technician is licensed, insured, and has experience working with septic systems. In some areas, septic professionals must be certified by local authorities or national organizations. Hiring a trusted septic pumping contractor can provide significant benefits for homeowners.
Check Reviews and References
Before hiring a company, check online reviews or ask for recommendations from neighbors or friends. A reputable provider should have positive feedback and a proven track record.
Get Multiple Estimates
For major repairs or replacements, it’s always a good idea to get estimates from several providers to ensure you’re getting fair pricing.
Ask About Their Services
A good septic service provider will offer a range of services, including inspections, pumping, repair, and even installation of new systems. Make sure they can meet your needs and offer ongoing support.
