Frequently Asked Questions
How Often Should I Treat My Water Tank?
How Often Should I Treat My Water Tank?
For most rainwater catchment systems, using it once a month is ideal. This helps keep your tank surfaces clean and free from contaminant buildup
Best Practices for a Clean Tank:
1. Monthly Tank Cleaning
- Follow the directions on the package.
- This breaks down green staining and odors, slimy film, and contaminant buildup that enter from roof runoff.
2. Clean Roof & Gutters the Right Way:
- Leaves, dust, and bird or rodent droppings can dirty your water.
- Before the rainy season or after heavy winds, clean your roof and gutters.
Important: Divert the dirty wash water away from the tank to avoid introducing debris.
3. After Heavy Weather:
- If you notice increased droppings on the roof or contaminant buildup in the tank, you may use it more frequently until your tank is clean.
4. Annual System Checkup
- Inspect the interior of the tank at least once per year.
- Remove accumulated sediment and check screens and filters for clogs.
By diverting the dirty cleaning water and maintaining a monthly cleaning schedule, you'll help keep your tank clean and extend the life of your rainwater system.
