English Instruction manual Combi Maintenance Water filter maintenance Regular cleaning / replacement of the Combi water filter will help to prolong the life of the pump. The sole purpose of the water filter is to prevent foreign debris from entering the pump itself. The time period between filter service can only be determined from the specific environment in which the pump is installed. We recommend cleaning or replacing the water filter a minimum of every 12 months.
