Understanding Your Septic System
A septic system is an underground wastewater treatment structure that uses a combination of nature and engineered processes to treat wastewater. It consists of a septic tank and a drain field. Understanding how your system works is crucial for effective troubleshooting and repairs.
Common Causes of Septic System Failure
- Clogged pipes
- Full septic tank
- Drain field saturation
- Tree root intrusion
- Improper maintenance
Step-by-Step Guide to Fixing a Failed Septic System
Follow these steps to diagnose and fix your septic system:
- Identify Symptoms: Look for signs such as slow drains, foul odors, and wet spots in your yard.
- Check the Tank: Inspect the septic tank for signs of overfilling or clogs. If the tank is full, it may need to be pumped.
- Pump the Tank: Hire a professional to pump the tank if it is full. This should be done every 3-5 years as part of regular maintenance.
- Inspect the Drain Field: Check for pooling water or soggy ground. If the drain field is saturated, it may need repairs or replacement.
- Clear Clogs: Use a plumbing snake or hydro jetting to clear any clogs in the pipes leading to the tank.
- Repair or Replace Components: If any components are damaged, such as the baffles or piping, replace them as necessary.
- Perform Regular Maintenance: Schedule regular inspections and pumping to prevent future failures.
