What is backflow?

Water distribution systems are designed so that the water flows through the system in one direction under normal hydraulic conditions. Disruptions in the normal hydraulic conditions within the distribution system may cause the water in the system to flow in the opposite direction. Backflow is the undesirable reversal of flow of non-potable water or other substances through a cross-connection into the piping of the public water system or the consumer's potable water system.

What is a backflow prevention assembly?

A backflow prevention assembly is a mechanism designed to prevent backflow. Backflow prevention assemblies only allow the water passing through them to travel in one direction. Should there be a disruption in the normal hydraulic conditions within a water distribution system the backflow prevention assembly would not allow the water to backflow into the drinking water system. Backflow prevention assemblies protect the drinking water supplies from becoming polluted or contaminated by a plumbing cross connection. The principal types of mechanical backflow prevention assemblies are the reduced-pressure principle assembly, the pressure vacuum breaker assembly, spill resistant vacuum breaker, and the double check valve assembly.

What is a cross connection?

A cross connection is a connection between the drinking water system and anything that may potentially pollute or contaminate the drinking water system. When a drinking water system is connected to another water system such as an irrigation water system there is a potential for the water that is used in the irrigation water system to backflow into the drinking water system if the proper backflow protection is not installed. These types of unprotected connections between drinking water supplies and any other source or system containing unapproved water or substances are called cross connections.

Who should take these courses?

Water suppliers, plumbing inspectors, health department personnel, building owners and managers, building engineers, private contractors and anyone else who is interested in how their drinking water is protected from possible contamination.

Does the class cost include the AWWA exam?

No. You must register directly with AWWA in order to take the exam and the test fee must be made directly to AWWA.

Are there any prerequisites required for the Cross Connection Specialist course?

Although we welcome all applicants into the Cross Connection Control Specialist course, you will not be able to take AWWA’s Cross Connection Specialist exam unless you already have your Backflow Tester certification.

What is the AWWA?

The American Water Works Association (AWWA) is the world’s largest educational and scientific organization dedicated to the promotion of safe drinking water. Link to AWWA FAQS

What do I need to bring with me to class?

Complete Class Notes and Binders will be provided for you. The WITS facility is also fully equipped with all the equipment you will need for training, as well as backflow practice test kits. You may bring your own test kit if you prefer, but kits will be provided for student use.

How do I register?
