If you’ve never heard of an RPZ valve, don’t worry—you’re not alone. Most homeowners don’t think about it until something goes wrong. But here’s the truth: having your RPZ (Reduced Pressure Zone) backflow device tested every year isn’t just a suggestion—it’s required by most municipalities to keep your water supply safe.
At Aqua Knight Plumbing, we take water safety seriously. That’s why we include annual RPZ backflow testing in our Aqua Knight Safeguard Membership—along with other exclusive benefits—for just $99 a year.
What Is an RPZ Backflow Device?
An RPZ valve is a critical component of your plumbing system that protects your clean drinking water from contamination. It prevents dirty or chemically treated water (from sprinkler systems, boilers, etc.) from flowing backward into your home’s main water supply.
Think of it as a bodyguard for your water, blocking any contaminants from sneaking in and keeping your household safe.
Why Do I Need Annual RPZ Testing?
Over time, RPZ valves can wear out, freeze, or get clogged. That’s why annual testing is required in many cities (including Elmhurst) to make sure your valve is functioning properly. Without regular testing, you could unknowingly risk contaminating your water—and possibly face city fines.
If you’re a business owner, landlord, or simply a homeowner with an irrigation system, this isn’t something to skip.
