Backflow is when there is a flow reversal in a home’s potable water system, which can cause contamination and unsafe drinking water. Home water systems can be contaminated with chlorine from pools and hot tubs, soap and detergents, human waste, pesticides, fertilizers, household chemicals or other common contaminants through backflow. Water flowing backwards out of your home can also contaminate the public water supply.
Reversal of flow happens when there is a significant change in water pressure. Pressure changes can be caused by power outages, air trapped in the pipes, failure of a pressure regulating valve, a break in the water main, or a high demand on your water supply.
Water from your main supply should only ever flow into your home and never in the opposite direction. This can be achieved through the proper installation and maintenance of backflow preventers in your home.
Backflow prevention devices ensure that your home drinking water stays safe and uncontaminated. A backflow preventer enables water to flow in one direction, but never allows it to flow the opposite way, thus preventing contamination.
Common Backflow Prevention Devices:
Double Check Valve Assembly (DCVA)
Reduced Pressure Backflow Assembly (RPBA)
Spill Resistant Vacuum Breaker Assembly (SRVB)
Reduced Pressure Principle Backflow Assembly (RP)
Backflow Testing Services in Calgary; Cross Connection Testing
You may receive a reminder letter from the City of Calgary about having your cross connection control device tested to ensure that backflow isn’t posing a risk of contamination to the public water system. If you have gotten a letter like this, you need to get a professional test done annually.
Make sure you hire a professional to inspect and test your backflow prevention device. You should have your backflow preventer inspected upon installation and once a year thereafter. Lone Star’s technicians offer the reliable, professional backflow testing Calgary trusts.
You can’t necessarily tell if your water supply is contaminated–it might look, smell, and taste completely normal even when it contains unsafe contaminants. This is why it is so important to have a reliable backflow preventer device and to have it inspected regularly. Any backflow preventer needs to be inspected and tested by a professional at least once a year.
