✅ What Is Backflow Testing?
Backflow occurs when contaminated water flows in reverse, potentially entering your clean water supply. A Backflow Preventer (or RPZ—Reduced Pressure Zone device or BPV – Back Pressure Valve) protects your home or business by blocking that reversal.
Our ASSE certified technicians test your RPZ, BPV, or backflow device to ensure:
-
Proper valve function
-
No pressure loss or leaks
-
Full compliance with Minnesota Plumbing Code
- We are ASSE 5130 and 5110 Certified (Backflow Prevention Testing and Backflow Prevention Rebuilder)
