A method and system for preventing water entering a dispenser from collecting in the containment pan. This method utilizes a shield or barrier placed inside the dispenser above the containment pan. The material used to form the barrier is insoluble in water but soluble in the hydrocarbons typically found in a dispensing system.

Method and system for keeping water from entering dispenser containment sumps

A method of repairing polyethylene fuel containment sumps used in underground storage systems in gasoline and diesel service stations without 'welding' the polyethylene, using suitable surface preparation, priming of the affected area, and sealing with a two part rubber compound.

Method to repair polyethylene containment sumps

A method of upgrading the area below a dispenser to contain accidental release harmful materials from contaminating the soil below grade without repiping, electrical changes, or concrete disruption.

Method for installing form in-place dispenser containment

A method of upgrading an existing unprotected submersible pump area with secondary containment to prevent accidental release of harmful materials from contaminating the soil below grade.

Form in-place submersible pump containment

A method of upgrading a below grade fill to prevent accidental release harmful materials from contaminating the soil below grade.

Upgrade of below grade fill to at grade fill

A method for fabricating a secondary containment system in place includes providing a support surface for bottom and side portions of the secondary containment systems and applying a thermoset resin material to the support surface.

Secondary containment system

Fuel dispenser handle

A user friendly vapor recovery nozzle with special signaling devices to signal and assure the customer of proper delivery of fuel and return flow of hydrocarbon vapors. In the preferred embodiment, the signaling devices include both a fuel flow indicator and a vapor flow indicator. The flow indicators can comprise one or more fuel and vapor driven balls, paddle wheels, propellers, spinners, blades, or vanes. In the preferred form, the vapor recovery nozzle has an inner fuel spout to discharge gasoline into a customer's tank and has an outer spout which cooperates with the inner spout to provide a vapor return passageway to return vapors emitted during fueling to a vapor return hose. The nozzle has a liquid sensing tube in the vapor return passageway to sense when the customer's tank is filled. An automatic shutoff valve cooperates with the liquid sensing tube to shutoff the supply of gasoline when the customer's tank is filled. The nozzle also has a venturi sleeve which can be connected to a condensate liquid pickup tube to remove condensed vapor in the vapor return hose. A flow control valve assembly is provided to regulate the flow of gasoline. Fuel flow indicators can be operably positioned in the flow control valve assembly. The flow control valve assembly can have transparent cap to view the fuel flow indicators. The nozzle can further has a vapor check valve to regulate the flow of vapors. Vapor flow indicators can be operably positioned and viewed in the vapor check valve.
