Even the best tank needs regular cleaning: dust, sand and sediment from the water network collect at the bottom over time. Regular cleaning keeps your water clean and your family healthy.
How often should you clean the tank?
Clean the tank at least every 6 months, plus an extra time after summer, after any problem in the water network, or if you notice a change in water colour or taste.
Cleaning steps
- Close the inlet valve and empty the tank completely through the drain valve or taps.
- Remove sediment from the base with a sponge or soft brush. Avoid metal brushes and sharp tools that scratch the inner layer.
- Wash the inner walls with clean water. You can use a disinfectant intended for drinking-water tanks, following the manufacturer’s instructions.
- Rinse several times with clean water until any smell of disinfectant is gone.
- Close the threaded lid tightly to keep out dust and insects.
- Refill the tank and let the taps run for a few minutes.
Common mistakes to avoid
- Using strong chemicals or cleaners not intended for drinking water.
- Entering the tank with shoes or using sharp tools.
- Leaving the lid open or broken.
- Forgetting to clean filters and pipes after cleaning the tank.
How a good tank helps
A smooth wall and a white food-grade inner layer make sediment easy to see and remove, and light-blocking layers reduce algae growth, so the tank needs cleaning less often.
Frequently Asked Questions
Can I use chlorine to clean the tank?
You can use disinfectants intended for drinking-water tanks at a diluted concentration according to the instructions, followed by thorough rinsing. Do not use strong chemicals not intended for drinking water.
Why does green algae appear inside the tank?
Algae grows when light reaches the water, which happens in single-layer or translucent tanks. Multi-layer tanks block light and greatly reduce algae growth.
