Is It Time to Get Your RPZ Valve Tested?

If you’re unsure when your Reduced Pressure Zone (RPZ) valve was last tested, it’s time to call a professional. Minnesota state law requires RPZ valves to be tested annually and rebuilt every five years to ensure safe drinking water and compliance with regulations.

Your RPZ valve prevents contaminated water from flowing back into your home’s water supply. Keeping it up to date is critical for your health and safety.

Why Do You Need an RPZ Valve?

Plumbing systems maintain specific water pressure to keep water flowing in the right direction. However, if the pressure drops, contaminated water can enter your drinking supply—a hazardous situation known as backflow.

What Causes Backflow?

Backflow can occur due to unpredictable factors outside your control, such as:

✔️ A nearby main break
✔️ The fire department using a hydrant
✔️ City water supply fluctuations

When pressure drops, appliances, pesticides, fertilizers, or other contaminants can flow backward into your drinking water.

How RPZ Valves Protect Your Water

✔️ An RPZ valve has two independent check valves and a monitoring chamber.
✔️ If either check valve fails, the RPZ releases contaminated water before it enters your supply.
✔️ This prevents backflow and ensures your drinking water remains safe.

When Should You Get Your RPZ Valve Tested?

✔️ If it’s been over a year, schedule an RPZ test immediately.
✔️ Minnesota law requires annual testing—don’t risk noncompliance.
✔️ If you notice missing or broken parts, have it inspected ASAP.
