DOUBLE CHECK VALVESBackflow Prevention / Double Check Valves

Altecnic double check valves are used to prevent the risk of backflow and back siphonage contamination in domestic dwellings, public and commercial buildings. The valves should be installed close to the water outlet such as taps, basin taps, showers and toilets to prevent back siphonage contamination to the water supply, should a mains supply pipe burst.
