Underground Drainage
Non Return Valves
Simple and effective device for reducing the risk of flood damage caused by surface water flowback through the underground drainage system.
Install within an access point between the facility to be protected and the main sewer, any flowback will automatically shut the valve.
In pumped drainage systems, for example, where effluent water is being pumped from a basement, the non return valve will help protect the system in the event of a power failure.
Integral closing handle allows valve to be shut manually for easy system maintenance or cleaning.
Meets with the requirements of the building regulations approved document H1.
Remember: Rodent control should be taken into account when redeveloping sites. This can be in the form of sealed inspection and intercepting traps such as the Hunter Non Return Valves, available in 110mm, 160mm and 200mm
