ACE NON RETURN VALVE
Non Return Valve is also called anti-flooding valve. Thanks to the smart design of its self-closing flap, the non return valve is designed to ensure the air and water tightness inside the sewer line against backflow yet allowing the normal discharge. It effectively prevents backflow of sewage, foul odour and flood water.
It has been tested to BS4514 and 5255 with test reports from recognized laboratories and universities.
