What Should You Do if Your Backflow Test Fails?

CMC Technologies – Backflow Testing & Solutions

If your backflow prevention device fails its annual test, it’s important to act quickly to protect your water supply and to comply with regulations. CMC Technologies helps property owners and facility managers understand their options and make the most cost-effective, compliant decision. Here’s what you need to know if your backflow test result isn’t up to standard.

1. Assess the Age of Your Backflow Assembly

Backflow preventers are designed for long-term use. Some assemblies have been working reliably for decades. Replacement based solely on age isn’t always necessary. Instead, focus on:

• Component condition: Identify which parts are causing the failure.
• Minor vs major repairs: If only rubber seals or similar minor parts need replacing, repair is likely the best option.
• Extensive deterioration: If there’s significant corrosion or coating breakdown, replacement may be more cost-efficient in the long run.

2. Availability of Repair Parts or Replacement

Not all backflow assemblies, especially older models, have easily accessible spare parts. At CMC Technologies, we maintain strong supplier relationship with Mid-West USA to to offer you spare parts of your test kit. However, local plumbing stores may not always carry what’s needed, making replacement the only practical choice for some outdated systems.

3. Cost Comparison: Repair vs Replacement

Several factors influence whether you should repair or replace a failed backflow assembly:

• Assembly size: Small units are often cheaper to replace than repair, especially if parts are unavailable.
• Downtime considerations: For critical water services, replacement can minimise service interruptions.
• Large assemblies: Facilities with larger units may benefit from keeping spare parts on site for quick repairs, as replacement costs for large assemblies can be significant.

4. How Complex is the Repair?

Modern backflow preventers are designed for straightforward maintenance, with features like modular check valves and lighter construction. Older assemblies may require more labour and expertise to repair. If your business has access to trained technicians and the right parts, even complex repairs can be completed efficiently.

Key Takeaways

A failed backflow device does not always mean full replacement is necessary. Consider the age, condition, availability of parts, repair complexity, and overall costs before making a decision. Consulting a professional like CMC ensures you remain compliant with regulations and maintain a safe water supply.
