Frequently Asked Questions
What is backflow?
In a potable water system, backflow is the flow of water in the opposite direction to the normal flow, caused by either backpressure or backsiphonage.
What is a cross connection?
A cross connection is any connection, actual or potential, between the drinking water system and a source of contamination or pollution through which backflow may occur.
What is a backflow prevention assembly?
A backflow prevention assembly is a mechanical device that only allows water to flow in one direction, therefore preventing backflow into the potable water supply. Some assemblies protect against both backpressure and backsiphonage, while others protect against backsiphonage only. The type of device or assembly used depends on the degree of hazard associated with the cross connection.
Why do backflow assemblies need to be tested?
Like any mechanical device, backflow assemblies can fail for various reasons. Because they protect our drinking water it is necessary to ensure these devices are operating correctly. Under the CRD cross connection control bylaw it is mandatory to have your backflow assembly tested annually.
Do you submit the test results to the CRD?
Yes. As soon as the test is complete you will recieve a copy of the test report by email and we submit a copy to the CRD for you.
What happens if a backflow preventer fails?
A failed device is required to be repaired or replaced under the CRD cross connection control bylaw. It is almost always more economical to repair a device than to replace it, that is why we will always make every reasonable attemp to repair your device first.
