Frequently Asked Questions
- 1. How often must my backflow preventer be tested? Most Racine properties—both residential and commercial—require annual testing; high‑hazard setups may need semi‑annual checks.
- 2. RPZ or DCVA—what’s right for my building? RPZs protect against higher hazards and are often required for commercial kitchens and boilers; DCVAs suit moderate‑risk irrigation or potable lines.
- 3. Do irrigation systems really need backflow protection? Yes—fertilizers and lawn chemicals can siphon backward without a certified device.
- 4. What if the assembly fails its test? We can usually rebuild the unit on the spot; if replacement is smarter, we’ll review options before proceeding.
- 5. Can I perform the certification test myself? No—state law mandates a certified tester; DIY results won’t satisfy code.
- 6. How long does a typical installation take? Most home installs finish in two to three hours; larger commercial valves may take half a day with minimal water shutoff.
- 7. Will you remind me about next year’s test? Absolutely—our system sends reminders well before your certificate expires.
