Why Proper Sizing Matters
Choosing the right tank size ensures:
- 🚿 Efficient waste breakdown
- 💧 Cleaner discharge water
- 🛑 Fewer clogs and odor issues
- 🔁 Longer service life (10–15 years without pumping)
If the tank is too small, it overloads quickly. Too large, and you’ll spend more than necessary.
