What is a Cccdi inspector?

The cross-connection control device inspector (CCCDI) approval program is coordinated by the FOS as a basic element of the water supply program. Actual registration and instruction is primarily conducted by the Environmental Resources Training Center, Edwardsville (ERTC at SIU-E).

Is backflow testing required in Illinois?

The State of Illinois requires that every backflow device be inspected annually by a certified backflow tester, and every city that operates a public water system is responsible for making sure that this is done.

What is a cross connection control device?

A cross connection control device is a mechanical device that stops the backflow of water into public drinking water.

What is Rpz certification?

RPZ Certification, Installation & Maintenance RPZ stands for Reduced Pressure Zone and refers to devices that are used to protect your drinking water supply from potential contamination by lawn irrigation systems, indoor fire sprinkler systems and other equipment.

Where are backflow preventers required?

Backflow preventers are placed on the main water line where the wastewater and freshwater connections meet. The device is a valve that automatically closes anytime a change in pressure occurs. Once the valve closes, sewer water can’t continue to travel in the wrong direction.

What is an example of a cross connection?

Common examples of cross-connections include a garden hose submerged in a pesticide mixture, a piped connection providing potable feed water to an industrial process, such as a cooling tower, or a submerged outlet of an irrigation system. Connections to firefighting equipment are other very common cross-connections.

What is a cross connection?

A cross connection is a point in a plumbing system where the potable (drinking) water supply is connected to a non-potable source. Pollutants or contaminants can enter the drinking water system through uncontrolled cross connections when back flow occurs.

What does a backflow inspector do?

For places that already have backflow preventers installed, your inspection will involve checking to make sure the devices are working properly. Your plumber may use test hoses in order to check pressure and they may dismantle your backflow prevention devices in order to ensure they haven’t worn down.

What is the purpose of an RPZ?

Reduced pressure zone assemblies, also known as RPZ valves, are extremely important. They’re used to keep contamination or pollution out of your water. Specifically, these devices are installed onto your plumbing system to help protect both drinking water and the city water supply.

Does an RPZ reduce pressure?

Reduced pressure zone assemblies (RPZ Valves) are extremely important. Reduced pressure zone devices provide the highest level of protection for your water supply. That’s why most municipalities and engineers across the country are requiring the use of these types of backflow prevention devices.
