A vacuum breaker prevents contamination of your home water supply. Most cities require them at the start of any irrigation system whether or not fertilizer or chemicals are injected into the system. Vacuum breakers partially restrict water pressure and flow, and are not rated for use under constant pressure.
Note: Check locally for building codes and backflow requirements in your area.
