Need a Backflow Preventer?
Backflow Prevention is the Law
To comply with Canadian Standards Association, the City of Edmonton Bylaw #17698, Epcor’s Cross Connection Control, and the Canadian Water & Wastewater Association, property owners must do the following to prevent backflow:
Remove any unnecessary cross connections and isolate your water system from the public’s.
Protect cross connections that can’t be eliminated with an approved backflow prevention device or assembly.
Ensure that all testable backflow preventers are tested annually by a certified tester, and all non testable devices are visually inspected.
Backflow Services FAQ
When there are connections between the water supply and sources of contamination, the fluid can reverse flow. This can cause the contaminated fluid to flow back into our potable water supply. It can be dangerous and potentially deadly. Backflow preventers prevent this from happening.
For all commercial, industrial and insititutes, a backflow preventer is required on all water services for the building (installed after your water meter). This is to prevent any possible contaminated fluid from backflowing back into the potable water supply. Backflow preventers are also required for irrigation, fire systems, and water make-up systems. Basically everywhere where contaminated fluid can flow back into the water supply.
Because of the nature of what a backflow preventer does, backflow preventers need to be tested annualy to be sure they are working and working correctly. In extreme high hazzard conditions, backflow preventers may need to be tested twice a year.
If a backflow preventer fails testing, it means it is no longer working correctly. At RBA Mechahical, we have the decades of expertise and diagnostic skills to troubleshoot any device failure. We troubleshoot the test results to determine the repairs required. Some devices will need replacement, but most can simply be repaired.
It is not recommended to repair a failed backflow preventer unless you are certified for backflow repairs. There are many delicate and moving parts inside the backflow preventer, and it is essential that only skilled technicians complete the required repairs.
As a rule, backflow preventers do not require maintenance. However, they do require annual testing. Failed tests will require repairs or replacement.
Yes! All repaired devices, or devices that have been replaced, must be tested to ensure the devices are working correctly before they are set into service.
Absolutely! Backflow preventers can fail right out of the box. Brand new devices can fail testing if they were not installed correctly, dropped or banged during shipping, or if the devices were subject to freezing temperatures. Always have your new devices tested before they are set into service.
