Question: 1 / 400

_______________________ is the correct mounting height for a RPZ?

6 inches to 5 feet above ground

12 inches to 6 feet above ground

12 inches to 5 feet above the ground

The correct mounting height for a Reduced Pressure Zone (RPZ) backflow preventer is situated between 12 inches and 5 feet above the ground. This specific height is established to ensure that the RPZ functions effectively while providing adequate accessibility for maintenance, inspection, and testing. The 12-inch minimum height protects the device from any potential contamination from flooding or standing water, while the upper limit helps maintain system integrity and regulation compliance. By positioning the RPZ within this range, it ensures that the device is both functional and adheres to safety standards mandated by plumbing codes. This height range is crucial in preventing backflow incidents that could compromise potable water supplies.
