Pentair 24" Cristal-Flo™ II Top Mount Filter T-240BP with 1.5" MPV

Pentair Cristal-Flo™ II 24" Top Mount Sand Filter T-240BP

The Pentair Sta-Rite® Cristal-Flo™ II 24-inch top-mount sand filter (Model T-240BP) is a rugged, high-capacity filtration solution designed to provide crystal-clear water for inground and above-ground residential swimming pools. Constructed from an extra-thick, one-piece molded thermoplastic polyethylene resin, the durable unibody tank offers immense structural strength and complete immunity to chemical corrosion and harsh weather conditions. This unit is equipped with an engineered 1.5-inch six-position top-mount multiport valve that features an easy-to-use manual lever, allowing pool owners to seamlessly switch between essential functions including filter, backwash, rinse, waste, closed, and recirculate. Internally, a sophisticated lateral grid assembly ensures uniform water distribution across the expansive 3.15 square feet of effective filtration area, keeping the sand bed perfectly flat to maximize debris-holding capacity and extend the duration between cleanings. It manages a robust design flow rate of up to 70 gallons per minute (GPM) at a maximum operating pressure of 50 PSI, optimizing hydraulic efficiency when paired with energy-saving variable speed pumps. Routine maintenance is made straightforward by an integrated continuous internal air relief system, a transparent sight-glass adapter for backwash monitoring, and a large, tool-free bottom drain plug for winterization. The dry weight of the Pentair Cristal-Flo II 24" Filter with its 1.5-inch multiport valve assembly is approximately 76 pounds (noting that it requires 300 pounds of specialized filter sand for full operational deployment), offering a heavy-duty, reliable, and low-maintenance centerpiece for modern pool pads.
