The Patented FlexWorks Loop System™, developed by OPW Fueling Containment Systems, represents the state of the art in a completely integrated, environmentally secure underground fuel delivery system. The system, by design, employs pre-fabricated factory assembled components which translate into dramatically reduced field labor and associated costs, and risk of installation errors. The installed product preserves total underground access to all piping connections, piping runs, and containment sumps for hassle-free inspection, maintenance, or repair without ever having to excavate or even remove a dispenser. The Loop System™ incorporates field-proven OPW technology into a simplified, completely integrated piping system design that facilitates easy inspection, identification, and repair of any problem that may develop, and enhances the capability for leak prevention. The OPW-FCS Loop System™ provides a radically new solution to minimize traditional fuel delivery system problems. The End Results are an exponentially higher level of environmental protection and reduced cost of fuel delivery system ownership.
