What Is Cross‑Connection & Why It Matters for Irrigation
A cross‑connection occurs when your potable water system is connected—directly or indirectly—to a non‑potable source like an irrigation system. Without proper safeguards, contaminants such as fertilizers, pesticides, or bacteria can enter your drinking water via backflow.
In Calgary and across Alberta, annual testing of backflow prevention assemblies is required by municipal and provincial regulations, with fines of up to $1,500 for non‑compliance.
Types of Backflow Prevention Devices We Use
We offer certified installation and testing of the following devices, selected based on your irrigation setup and risk level:
- Pressure Vacuum Breaker (PVB): Recommended for many residential irrigation systems, installed above the highest point to prevent siphoning.
- Double-Check Valve Assembly (DCVA): Features two check valves in series for added reliability.
- Reduced Pressure Zone Device (RPZ or RPZD): Ideal for high-hazard systems like those injecting chemicals—provides robust protection.
Air Gaps: A simple, highly effective no-moving-parts solution for critical applications.
Importance of Annual Testing & Maintenance
Why annual testing is non-negotiable:
- Mechanical wear: seals, springs, and valves degrade over time
- Compliance: Most municipalities—including Calgary—mandate testing by a certified technician every year.
- Reliability: Early detection avoids system failures, contamination risks, and fines.
Best practices:
- Schedule testing in early spring, before reactivating your irrigation system—this aligns with the City’s expectations.
- Keep records of testing and certifications for regulatory compliance and peace of mind.
