Pentair TR100/TR140 24" Tank Foot

The Pentair TR100/TR140 24" Tank Foot (part number 154530 or 154530Z) is a specialized structural support base designed exclusively for the lower chassis of high-capacity Pentair Triton II side-mount sand filtration systems, specifically the large-diameter 30-inch TR100 and 36-inch TR140 models. Injection-molded from a thick-walled, high-impact, and chemically inert black polymer composite, this circular 24-inch diameter base ring cradles the rounded bottom hemisphere of the fiberglass filter vessel. Its primary structural role is to serve as a load-bearing foundation that uniformly distributes the massive, concentrated downward weight of the fully loaded filter—which contains hundreds of pounds of dense silica sand and water—preventing the tank from tipping, shifting, or developing localized stress fractures on the pool equipment pad. By elevating the lower dome slightly off the ground, it protects the integrated bottom drain plumbing assembly from direct friction and ground moisture while keeping the entire pressurized structure level under heavy hydraulic operating pressures up to 50 PSI. Built to endure relentless outdoor UV weathering, intense solar heat, and continuous exposure to pooled equipment pad water containing chlorine, bromine, and winterizing acid washes, this robust tank foot resists structural flattening and cracking over decades of service. Due to its wide-diameter, rigid ring architecture engineered to support industrial-scale residential and commercial loads, this individual tank foot carries a net product and shipping weight of approximately 5.25 to 6.00 pounds.
