What type of penetration fittings should all dispenser-sump entries be fitted with to prevent the escape of released liquids?

Dispenser-sump entries must be fitted with liquid-tight penetration fittings to effectively prevent the escape of released liquids. These fittings are designed to create a secure barrier against leaks, ensuring that any potential liquid release remains contained within the sump.

Liquid-tight fittings are crucial for maintaining the integrity of underground storage systems, as they help prevent environmental contamination and protect both the surrounding area and groundwater from hazardous materials. Ensuring that penetration fittings are liquid-tight also aligns with regulatory compliance and industry best practices aimed at preventing leaks and spills during the operation of fuel dispensers.

This emphasis on liquid-tight design reflects a wider commitment to safety and environmental stewardship within the industry, where even small leaks can lead to significant consequences. Proper installation and the use of the right type of fittings are essential components in safeguarding against such risks.
