Each time the Purge Valve is opened, dirt and built-up
contaminants are flushed from the system. This cleans the
filter, maintains optimal water flow and extends the filter's
life. Ensure the system is flushed ideally every 10 liters, or
every 3 liters for cloudy or tea-colored water.

the water is the same color as the source water and free
of bubbles.

your risk of gastrointestinal illness.
