When it comes to your home’s plumbing, some of the most important safety features are the ones you never see. One of those is the RPZ (Reduced Pressure Zone) backflow preventer—a device that protects your home and your community from contaminated water. But here’s the catch: this device only works if it’s regularly tested and maintained.
So, what exactly is an RPZ backflow preventer? It’s a specialized valve that stops dirty water from flowing back into the clean water supply. This could include anything from lawn fertilizers and pesticides to cleaning chemicals and even sewage. If pressure drops in the system, like during a water main break or heavy usage, the backflow preventer steps in to keep contaminated water from entering your home’s drinking supply.
In Illinois, RPZ testing isn’t just recommended—it’s required annually. Why? Because backflow events can pose serious health risks. And unfortunately, just having the device installed isn’t enough. Over time, parts can wear down or fail, and without regular testing, you might not know there’s a problem until it’s too late.
That’s where Aqua Knight Plumbing comes in. We include annual RPZ backflow testing as part of our Safeguard Membership, which covers a wide range of preventative services for just $99 a year. This membership is designed to protect your home, save you money, and keep your plumbing working safely and efficiently all year long.
