Backflow Testing

Professional Backflow Testing in Calgary

When the water flow in your plumbing has become reversed and begins entering your home or business, the issue is referred to as backflow and the result can be harmful contamination to your water supply. If you suspect you have a backflow issue, your best bet is to get your water flow tested by the licensed plumbers at Commercial Mechanical Services. Providing professional backflow testing in Calgary, you can rely upon our experts to properly assess your backflow situation, test your backflow device and determine the best way to restore your natural water flow as quickly as possible.

Importance of the Backflow Prevention Device 

The backflow prevention device is installed onto your plumbing system to protect your drinking water from contaminants. Backflow devices in Calgary are required where the water main is routed into your home as well as for irrigation systems, fire suppression systems and large boilers—places where contaminants can enter your water supply in various ways. 

Without an effective backflow device in place, chemicals and other contaminants will remain in your water system and can be present when you turn on a faucet. Backflow devices are like a one-way gate for water. They consist of one or more check valves that that close when water flow reverses, preventing anything in the water from spreading into your drinking supply. 

Because backflow devices protect your water, it’s very important to have them tested on a regular basis. You don’t want a backflow issue to arise while your backflow device has stopped working, which is why Commercial Mechanical Services offers backflow testing in Calgary. 

Signs You Need a Backflow Test

Backflow happens any time the water flow reverses between your private system and the city’s supply system. Your backflow device needs to be working correctly to keep your clean water safe for use. Signs it’s time for a backflow test in Calgary include:

 Age of your device: To ensure the safety of your drinking water, you should have your backflow device tested annually. While you may not think there are any problems, a professional could detect unseen issues that can lead to major problems later.

 Device irregularities: There are also visual signs to pay attention to. If you notice anything strange about your backflow device, it’s time to get it tested. Visible issues include leaks, dripping water and sporadic discharge. 

 Water quality: The most significant indicator you need a backflow test is the water quality in your home. If your clean water supply suddenly appears to be cloudy or discoloured, you need to get your backflow device tested. Even if the discolouration is in a hose or sink you don’t drink from, testing is essential. Don’t consume any water that looks strange and call a professional immediately to solve the problem.

A Well-Maintained System Results in Savings

Because human waste, bacteria and other harmful impurities may enter your water flow as a result of backflow, it’s imperative to have the backflow testing completed by qualified professionals. Experts usually recommend having your system professionally tested at least once per year to ensure everything is operating as it should be. Not only does regular backflow testing help you avoid major risks to your health, but having a well-maintained system can also help you avoid future costly plumbing repairs.
