Unexpected public sewer surcharge flooded basement plant room.

Urban drainage is challenged with storm events causing flooding of property.

Foul connections to public sewers from commercial and retail properties can be protected from the damage of sewer surcharging by installing Check-Flex G5 valves.

The valves are fitted by an expanding clamp and can be installed quickly even on live flows.

The low headloss of the 225mm inline rubber valve in the video, means that even foul flows will pass through the valve without obstruction.

The complex smooth upstream profile prevents ragging and the Neoprene reinforced construction provides years of service, even in high temperature washdown areas with steam cleaning.

The valve is unaffected by grease, oils and detergents found in commercial kitchens and food plants.

Inline rubber valves are built to work in harsh chemical and high temperature sites and there are many in service for decades.
