MaintenanceOn systems without our automatic filter, clean the filter bag as needed, usually about every two months in a typical 4-person household. This is done by retrieving the bag then inverting it over a garbage can and shaking the contents into the garbage. You may want to hose it out now and then to increase its flow rate. Replace the filter bag about once a year. For our automatically filtered systems, once a year, spin off the black filter vessel top with the large wrench provided. Reach inside and roll the water diffuser over into the vertical position. Scrap any solids or congealed materials from on top of the sand and dispose in the garbage. If it's been years since you checked the sand, and you find it to be coated with a tight debris layer, clean the sand along the filter vessel's entire inside wall, as debris will have traveled down that wall as the water flowed to cleaner sand lower in the vessel. After you're sure all sand is clean (i.e., free of solids and "clumps"), it should be level and within 4" of the bottom of the water diffuser pipe/inlet pipe, but no higher than the bottom of that pipe. Add sand as required. Use only 12-Grit sand, as too much water pressure will be lost through the use of finer sands. Roll the diffuser back to horizontal. Tightly secure the top back on the filter vessel. FAILURE TO PROPERLY MAINTAIN YOUR FILTER CAN CAUSE PUMP FAILURE AND/OR DOWNSTREAM DAMAGE TO THE EMITTERS.
