Pentair Cristal-Flo™ II 26" Top Mount Sand Filter T-300BP-2 with 1.5" MPV

The Pentair Sta-Rite® Cristal-Flo™ II 26-inch top-mount sand filter (Model T-300BP-2) is a highly robust, high-capacity filtration solution meticulously engineered for large residential above-ground and standard inground swimming pools. Molded from an extra-thick, single-piece thermoplastic resin, this heavy-duty unibody tank is built for lasting structural stability and complete protection against aggressive chemical treatments, rust, and cracking under intense outdoor UV exposure. This specific model features a high-performance 1.5-inch six-position top-mount multiport valve that grants pool owners seamless manual control over all vital circulation settings—including filter, backwash, rinse, waste, closed, and recirculate—with a single rugged lever. Internally, a sophisticated lateral grid and collector hub assembly ensure highly uniform water distribution across its expansive 3.69 square feet of effective filtration area, maintaining a perfectly flat sand bed to optimize particle trapping while extending the runtime between required cleaning cycles. It handles a robust continuous operating pressure of 50 PSI and effortlessly supports a maximum design flow rate of up to 75 gallons per minute (GPM), pairing efficiently with modern variable-speed pool pumps to achieve substantial seasonal energy savings. Routine upkeep is further simplified by a built-in continuous internal air relief system, an easy-to-read pressure gauge, a clear sight glass for monitoring backwash water quality, and a large bottom drain plug for fast, tool-free winterization. The dry shipping weight of the Pentair Cristal-Flo II 26" filter tank body with its 1.5-inch multiport valve assembly is approximately 51 pounds (noting that full operational deployment requires an additional 300 pounds of specialized filter silica sand), offering a durable, low-maintenance centerpiece for premium water management.
