RPZ Backflow Prevention Test Tips
Under the guidelines of a Cross-Connection Control Program a Backflow Preventer is required whenever a direct or in-direct cross-connection in a public or private water system exists. The Reduced Pressure Principle valve is designed for high hazard installation where back-pressure and back-siphonage could occur.
A backflow prevention assembly is used to protect water supplies from contamination or pollution.
In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower etc. When pressure fails or is reduced as may happen if a water main bursts, pipes freeze or there is unexpectedly high demand on the water system, the pressure in the pipe may be reduced and may allow contaminated water from the ground, from storage of from other sources to be drawn into the system. To prevent such an occurrence, many regulatory departments require there to be an air gap or mechanical backflow prevention assembly between the delivery point of mains water and local storage or use where submerged mains inflow is permitted a backflow prevention assembly is required. In this way the backflow prevention assembly protects the potable water system from contamination hazards which can be severe. There are over 10,000 reported cases of backflow contamination each year. Some cases can be fatal.
Only a licensed and certified backflow tester with an approved differential pressure gage can test an RPZ
