What is the lifespan of a pair of Phoenix Berkey filters?
According to the manufacturer, a pair of Phoenix Gravity elements filters about 20,800 litres of water, or 10,400 litres per element. This limit should not be exceeded.
How many years this represents
| Water filtered per day | With 2 elements | With 4 elements |
|---|---|---|
| 5 litres | About 11 years | About 22 years |
| 10 litres | About 5 and a half years | About 11 years |
| 20 litres | Nearly 3 years | About 5 and a half years |
These durations are theoretical. Water with a high particle load clogs the elements faster: the quality of your water matters as much as the quantity.
How to check the condition of your Phoenix elements
- The red dye test: if the filtered water stays clear, the elements are filtering correctly. If it turns red, they are incorrectly fitted or have reached the end of their life. The steps are explained in How to perform the red dye test?. This test does not apply to PF-2 elements.
- The flow rate after cleaning: as the elements near the end of their life, cleaning restores the original flow rate less and less.
