Frequently Asked Questions (FAQ)
Do enzyme additives really work in septic systems?
They can help break down organic matter and boost bacterial activity, especially after heavy chemical use or neglect. However, regular septic maintenance and pumping remain essential. For healthy tanks, enzymes are a useful supplement but not a substitute for good habits.
How often should I add enzymes to my septic tank?
Most products recommend monthly use for ongoing maintenance. Always follow manufacturer instructions for the right dosing schedule.
Are enzyme additives safe for all septic systems?
High-quality, septic-safe enzyme blends are generally safe for all modern and traditional tanks. Avoid products with harsh chemicals or additives that could damage plumbing or leach fields.
Can I skip septic pumping if I use enzyme additives?
No. Even with regular enzyme treatments, solid waste and sludge still build up over time and must be removed by pumping every 2–5 years.
What’s the best way to keep my septic system healthy?
- Use water efficiently
- Limit harsh chemical use
- Add a quality enzyme treatment monthly
- Have your tank inspected and pumped regularly
