Rupture Basins

All of Pryco’s day tanks (including double walled versions) may be fitted within an open-top, secondary container or dike, referred to at Pryco as a Rupture Basin. All Rupture Basins are U/L Listed - #MH12807, “Open Top Diked
Aboveground Tank for Flammable Liquids”.

Rupture Basins are available in either 150% (option #385) or 200% (option #386) models. Both are sized according to the accompanying day tank. (Note - 200% Rupture Basins are required in the City of New York.)

Rupture Basins, like all Pryco Tanks, are fabricated of heavy gauge steel by certified welders. Each tank complies with NFPA 30. Since a Rupture Basin is open-dike, it cannot be pressure tested.

Each Rupture Basin has a drain the same size as the day tank and a ½" NPT Threaded Pipe Connection for an optional #295 or #395 Leak Detector. Also as an option (#341), the inner tank drain may be piped through the outer shell. The Rupture Basins are painted Pryco (medium) Gray or an industrial color of choice.

A Weatherproof Cover (Option # 335RB) with a plexi-glass inspection port may be included to preserve the integrity of a dry container, especially when an optional leak detector is installed.
