Backflow Test Kits
Backflow Assembly Testers (BAT) are trained and certified professionals who provide testing of backflow prevention assembly devices in a variety of settings including, municipal, industrial, business, and residential. Backflow Assembly Testers and Cross-Connection Prevention Specialists are a vital part of protecting drinking water systems. Branom Instrument Co. supports these professionals by offering best-in-class sales and service for backflow test kits used in cross-connection and backflow prevention.
Backflow test kits are instruments used by Backflow Assembly Testers (BAT) which measures the function of backflow prevention assemblies. A test kit includes a pressure gauge (analog or digital) and three-needle valves. Each valve connects to test cocks on the backflow prevention assembly using a long hose. As water flows through the hoses, the gauge reads the pressure. These pressure readings are then compared to standards set by the American Water Works Association (AWWA) and the Foundation of Cross-Connection Control.
To ensure the accurate and proper functioning of backflow test kits it is necessary that they are tested and certified with the frequency determined by the local administrative authority.
The annual test includes calibration and checking and testing all valves and hoses for damage or excessive wear. Annual backflow test kit calibration, repair, and certification should always be performed by a company that has the right equipment and tests to NIST standards.

Understanding Backflow and the Importance of Backflow Test Kits
Potable water contamination results from backflow or issues with cross-connections. Cross connections are links where contaminants can enter a potable water distribution system. They also increase the risk of backflow, which occurs when the flow of water reverses, causing changes in pressure. This pressure difference can pull contaminants such as humane waste, fertilizers, pesticides, and dirty water into the potable water system.
Backflow prevention assemblies connect to water pipes and prevent backflow by only allowing water to flow in one direction. The assemblies come in several configurations and are used for commercial, industrial, and residential potable water systems. Backflow prevention assemblies must be inspected annually by a certified Backflow Assembly Tester (BAT) or Cross-Connection Specialist to ensure proper operation.
Backflow Test Kit Certification Regulations
Test kits need to be calibrated and certified annually, or whenever you suspect that they are not working properly. For information about certification requirements in your area, consult your local administration authority.
