Additional information concerning flow rates on backwashing filter systems

Service Flow Rate - The rate (in gallons per minute) at which the media can effectively treat your water. Please note that most systems will allow a higher flow rate through them than the media can treat, so should your water demands exceed the systems capabilities some of the water will pass through untreated. NOTE: Service flow rates are based on the manufacturers recommendation for maximum contaminate removal, lower contaminate levels may be effectively treated at higher flow rates.

Backwash Flow Rate - The minimum rate (in gallons per minute) that needs to be available for proper backwashing of the system. This is not a constant rate, your water source just needs to be capable of supplying the shown rate for backwashing. NOTE: Using a system with less than the recommended backwash rate may be possible, however, doing so will decrease media life and will negate the 30-day satisfaction guarantee. (The warranties on the tank and control head will remain unaffected)

Special Note on Pyrolox Systems - Flow rates on the Pyrolox systems are given in a range. The lower service flow rate is the manufacturers recommend rates, the higher number is actual rates that we have had successful treatment. On backwashing rates the higher number is the manufacturers recommend rate, the lower number is the rate that has been successfully used. NOTE: The higher your contaminate level the lower effective service flow rate you can expect and a higher backwash rate is recommended.
