Further Information

Application

The backflow preventer is a hydraulic protection device designed to prevent polluted water from flowing back into the mains supply network. This type of backflow may occur when the pressure in the mains supply network changes and causes a reversal of the flow. The backflow preventer is installed between the mains supply network and the internal consumer circuit in water supply systems and creates a safety zone, which prevents the water in the two circuits from coming into contact.

Design

The ‘BA” Backflow Preventer is a verifiable mechanical device designed to prevent contamination of the wholesome water by either back-siphonage due to a reduced or negative pressure in the mains water supply or system back pressure from the water installation within the premises.

The device consists of an arrangement of water fittings within three pressure zones having different obturators and a dump valve. When backflow or backpressure conditions occurs, the device provides an atmospheric separation between the wholesome water system and the contaminated fluid.
