About Febco

Its extensive catalogue includes pressure vacuum breakers, double-check valves, reduced pressure zone assemblies, strainers, wall hydrants, ball valves, repair kits and related accessories. Febco's backflow preventers are designed to prevent the reverse flow of toxic fluids from entering into the potable water supply due to back-siphonage or back-pressure. They feature a bronze body for durability, threaded quarter-turn ball valves for controlling water flow, top-mounted test cocks for periodic testing & maintenance, spring-loaded check valves for preventing backflow and a pressure differential relief valve for relieving excess pressure buildup. The brand's Y-pattern strainers are installed in water piping systems to capture solid particles from flowing water and prevent damage to backflow preventers. They have recessed screen seats to assure accurate screen alignment and are available in inlet sizes ranging from 2-1/2 to 10 inches.

Febco Competitive Advantages

SentryPlus Alert Technology

This technology is used for providing automatic flood detection on backflow preventer assemblies and signalling excessive relive valve discharge that could cause severe damage. This technology is used by Febco MasterSeries backflow preventers with an integrated flood sensor that allows a multichannel alert function triggering one or more notification methods for quick action. This sensor is designed to continuously monitor for potential flood conditions. The SentryPlus alert system can be integrated into the existing backflow preventer without taking it off the line, thus preventing downtime and reducing labour costs.

Frequently Asked Questions

How does a duplex strainer work?

Turn the handle to the centre directly over the inlet. Now open pet cocks on both basket covers.
Slowly fill the chambers with line fluid. Close pet cocks when fluid starts to flow from them.
Allow the system to gradually reach normal operating pressure and temperature. Check for leaks at this time.
Make sure that all basket cover knobs and bolts are securely tightened.
Rotate the handle until it directly comes over one of the chambers. Avoid leaving the handle in the centre position, or both baskets will become clogged, requiring the system to be shut down for cleaning.
