Compact backflow preventers from Honeywell ensure contaminated water cannot flow back into the public mains supply.
Honeywell’s BA295 compact backflow preventer ensures that contaminated water cannot flow back into the public mains supply. These valves are designed to meet all requirements of the UK Water Regulations Advisory Scheme and use the well proven RPZ (reduced pressure zone) principle. They protect drinking-water systems against back pressure, back flow and back siphonage. Their design minimises the number of spares required for servicing. The housing is made of red bronze, with a choice of DN15 to DN50 (1/2 to 2 in) screwed connections, and these valves provide a neat and cost-effective alternative to providing an air gap to isolate water systems. Maintenance is simple as there is unrestricted access to all internal components, and the discharge valve is mounted on the underside.
