PCI TS Series Grade Level Transition Sumps provide secondary containment where aboveground steel piping connects to underground fiberglass or flexible piping. Applications include aboveground storage tank (AST) connections, vent lines, system low points, and accessible underground equipment such as ball valves.

Built from 100% corrosion-resistant fiberglass, the TS Series combines a large access opening with multiple coupling and cover options for installation, inspection, and service.

Flexible Piping Applications

The TS Series accommodates piping transitions and can serve as an intermediate sump at a system low point or a containment enclosure around underground valves.

Forged Steel Couplings

Forged steel couplings provide durable piping connections that resist deterioration from UV exposure. Couplings are ordered separately to suit the piping configuration.

Stainless Steel Options

Stainless steel coupling options are available for installations requiring additional corrosion resistance.

Large Access Opening

The large opening provides room to install piping and reach connections and equipment during inspection and maintenance.

Duo-Molded Fiberglass Construction

PCI’s Duo-Molded Technology combines two layers of fiberglass with high glass content for strength and fuel resistance.

Brite-White Interior

PCI’s Brite-White interior reflects light for better visibility and helps identify leak points during inspection and service.
