Pentair Cristal-Flo® T-BP- 30in Tank Pedestal

The Pentair Cristal-Flo® T-BP 30" Tank Pedestal (part number 23900-0105A, featuring integrated insert tracking) is a heavy-duty foundational base replacement component engineered exclusively for high-capacity, vertical pool and spa sand filtration systems. This critical original equipment manufacturer (OEM) structural platform is tailored specifically to accommodate the expansive 30-inch diameter footprint of the Pentair Sta-Rite Cristal-Flo T-BP Series High-Rate sand filter—most notably matching the structural layout of the maximum-capacity model T-300BP-2.

Injection-molded from a thick-walled, high-impact, and weather-stabilized engineering polymer composite, this wide-set circular pedestal ring is built to support extreme static weight distributed under structural operating constraints. Its primary operational role is to isolate and safely cradle the curved lower hull of the 30-inch thermoplastic filter vessel, elevated above the raw concrete equipment pad floor. By locking the heavy bottom half of the tank into a perfectly leveled and nested configuration, it evenly dissipates the massive downward structural load generated by 300 pounds of wet silica sand media, internal water volumes, and high-velocity circulation streams. This rigid stabilization prevents localized stress fracturing of the tank hull and minimizes systemic vibration shear during heavy flow cycles or sudden pump startup surges, allowing the pressurized vessel to continuously sustain internal operating metrics up to 50 PSI.

Engineered to endure decades of demanding outdoor weathering, pooling moisture, and shifting seasonal thermal expansion cycles, its premium composite resin completely resists material softening, structural warping, environmental stress-cracking, and advanced chemical oxidation from direct exposure to UV radiation and localized pool chemical splashes. Due to its wide-diameter ring geometry, reinforced structural columns, and substantial factory-packaged shipping footprint ($21 \times 17 \times 7\text{ inches}$), this genuine replacement filter pedestal base assembly carries a standalone product and net shipping weight of approximately 5.40 to 6.20 pounds.
