Sta-Rite delivers the unique benefits of D.E. filtration in a variation of their proven modular media technology. A single replaceable grid delivers water of superior quality without the complex workings of other D.E. filters. This innovative one-piece design is fully back-washable and can be plumbed with or without a backwash valve. 2 in. union valves are included for installations electing not to use a backwash valve. For dip-down cleaning, simply remove the filter lid and hose off in place. No more hassle of tearing down the grid assembly for cleaning and servicing. Contemporary style and matte black finish looks attractive in any pool setting.
