RPZ Backflow Testing & Prevention in Southeast Minnesota

What Is an RPZ Backflow Preventer?

An RPZ backflow preventer is a specialized plumbing device that stops contaminated water from flowing backward into your clean water supply. Without it, changes in water pressure could allow chemicals, waste, or bacteria to mix with your drinking water. This device is especially important for properties with irrigation systems, fire sprinklers, boilers, and other high-risk plumbing setups.

How Does Backflow Happen?

Water is meant to flow in one direction through your plumbing system. However, pressure changes can cause it to reverse, pulling contaminated water into your drinking supply. This happens due to:

• Backpressure – When downstream pressure becomes stronger than your main water supply pressure, forcing unwanted water backward into the system.
• Backsiphonage – When a sudden drop in water pressure (like from a main break or high demand) creates a vacuum effect, pulling non-potable water into the clean supply.

Why Are RPZ Backflow Preventers Required?

Most cities and municipalities require RPZ devices to prevent chemicals, fertilizers, or other hazardous substances from entering the public water supply. Regular testing ensures these devices are working correctly, keeping your water safe and compliant with local regulations.
