When Arlington Heights homeowners and businesses need professional backflow testing & installation services, they turn to Plumbers 911 Chicago. We've been serving the Arlington Heights community and surrounding Cook County neighborhoods with expert plumbing solutions backed by licensed, bonded, and insured technicians.
Backflow prevention devices protect Arlington Heights' drinking water supply from contamination caused by cross-connections in plumbing systems. Illinois EPA regulations and Arlington Heights village ordinances require annual testing of backflow prevention assemblies on commercial properties, irrigation systems, fire sprinkler systems, and certain residential installations. Plumbers 911 provides certified backflow testing, repair, and installation throughout Arlington Heights.
Backflow Prevention Services
Annual Backflow Testing — Illinois requires annual testing of all backflow prevention assemblies by a certified tester. We test RPZ (Reduced Pressure Zone) valves, double check valve assemblies (DCVA), and pressure vacuum breakers (PVB). Test reports are submitted to the Village of Arlington Heights and Illinois EPA as required.
Backflow Device Installation — New installations for commercial properties, lawn irrigation systems, fire sprinkler connections, boiler systems, and any cross-connection hazard identified by the Arlington Heights water department.
Backflow Repair & Replacement — When a backflow device fails its annual test, we diagnose the failure, replace internal components (check valves, relief valve, springs), and retest. If the assembly is beyond repair, we replace it with a new unit.
Cross-Connection Surveys — We identify potential cross-connections in your plumbing system and recommend the appropriate level of backflow protection per Illinois Plumbing Code.
Backflow Testing & Installation Costs
Annual Backflow Test — $75–$150 per device (residential irrigation). Commercial properties with multiple devices receive volume pricing.
Backflow Device Repair (failed test) — $150–$500 depending on parts needed. Internal rebuild kits for RPZ valves are the most common repair.
New Backflow Device Installation:
- Pressure Vacuum Breaker (PVB): $300–$800 installed
- Double Check Valve Assembly (DCVA): $400–$1,200 installed
- Reduced Pressure Zone (RPZ): $800–$2,500 installed
Pricing depends on pipe size, location, and installation complexity.
