Backflow Testing in East Wenatchee, WA

Certified Backflow Assembly Testing in East Wenatchee

Backflow prevention assemblies protect the public potable drinking water supply from cross-connection contamination. When sudden hydraulic pressure drops occur in the municipal distribution main—due to firefighting water draws, a major water main fracture, or heavy summer agricultural irrigation demands—a back-siphonage or back-pressure event can pull hazardous fertilizers, pesticides, stagnant lawn chemicals, or industrial wastewater backward into the domestic drinking supply.

Under Washington Administrative Code (WAC 246-290-490) and local East Wenatchee Water District regulations, all property owners with irrigation systems, dedicated fire suppression lines, or commercial cross-connections must have their backflow assemblies inspected and certified annually by a state-licensed Backflow Assembly Tester (BAT). Whether you own an orchard parcel along the Grant Road corridor, an irrigated lawn in Fancher Heights, or a commercial restaurant near the Valley Mall Parkway corridor, our certified specialists ensure reliable compliance.

Common Backflow Assemblies We Test & Service

Our licensed testers calibrate and repair all state-approved backflow assemblies:

• Double Check Valve Assemblies (DCVA): Commonly installed on residential lawn irrigation systems, domestic fire sprinkler lines, and multi-family service connections to guard against low-to-moderate hazard backflow.
• Reduced Pressure Backflow Assemblies (RPBA / RPZ): Required for high-hazard connections where toxic contaminants—such as agricultural chemical injectors, commercial boilers, dental clinics, or car washes—could contaminate the municipal water supply.
• Pressure Vacuum Breakers (PVB): Outdoor irrigation assemblies installed at least twelve inches above the highest downstream sprinkler head to prevent back-siphonage. In winter, these assemblies must be thoroughly winterized to prevent damage covered under our frozen pipe repair services.
• Spill-Resistant Vacuum Breakers (SVB): Compact assemblies installed in tight indoor spaces where water spillage during operational relief is unacceptable.

What to Expect During Your Annual Backflow Inspection

Our testing procedure is thorough and non-intrusive:

1. Visual Inspection: We verify proper shutoff valve positioning, ensure the test cocks are undamaged, and confirm compliance with minimum elevation clearances above grade.
2. Precision Differential Pressure Testing: Utilizing certified, calibrated multi-valve differential pressure gauges, we measure the exact cracking pressure of each internal check valve and confirm proper air-inlet valve opening and relief valve discharge thresholds.
3. Same-Day Repairs if Required: If grit or mineral scale from East Wenatchee's hard water prevents a rubber disc from seating tightly, our service trucks carry factory rebuild kits to clean, reseat, or replace springs and seals on the spot.
4. Documentation & Filing: Upon passing inspection, we generate the official Washington State compliance test report and submit copies directly to the appropriate regional water purveyor on your behalf.
