Why Backflow Prevention Matters
- Irrigation water with fertilizer and pesticides can't flow back into the drinking supply
- Pressure drops in the main line create back-siphonage risk without a working assembly
- Annual testing confirms the assembly holds the required pressure differential
- Failed assemblies must be repaired before irrigation service is restored
