Overfill prevention is currently required by the Federal EPA to eliminate any chance of overfilling the UST. The approved methods for overfill prevention include a positive shut-off valve or a slow-down device (ball float). A positive shut-off valve is installed into the drop tube of the UST. The EPA allows a positive shutoff valve to fill a UST to 95% of its capacity. When the UST is filled close to 95% full, the overfill prevention valve will engage and shut off the fuel delivery. A positive shutoff overfill valve is much easier to install when upgrading an existing UST because a drop tube can be easily accessed without excavation. Overfill prevention valves can be used in non Stage I, Dual Point and Coaxial Stage I systems.
