Anti Syphon Vacuum Breakers and Check Valves

Back Flow Prevention is installed at the start of many irrigation systems including Drip Irrgigation Systems.  The purpose of a Back Flow Prevention Device (Anti-Syphon Vacuum Breaker)  is to eliminate the potential for a reverse flow of water back into a household water source.  This is paritcularily critical for systems using a fertilizer injection system.  Although not commonly required for Drip Systems, a back flow prevention device is often mandatory for Irrigation Sytems which are plumbed into a household water supply.
