Protecting your drinking water. Ensuring municipal compliance.<\/b><\/h3>

A backflow preventer is one of the most important components of your irrigation system. Its job is simple but vital: it prevents contaminated water\u2014containing fertilizers, pesticides, or animal waste\u2014from flowing backward into your clean drinking water supply.<\/p>

Because of this high stakes safety role, most municipalities across Metro Vancouver (including Surrey, Delta, Langley, and White Rock)<\/b> require that these devices be tested and certified annually<\/b> by a licensed professional.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

      The Hazards of “Backflow”<\/h2>

      Backflow usually occurs during a “pressure drop” in the city water main (like when a fire hydrant is opened or a water main breaks). This creates a vacuum effect that can suck stagnant irrigation water into your home\u2019s faucets.<\/p>

      Common Causes of Failure:<\/b><\/h3>

      Worn Rubber Seals<\/span>:<\/b> Over time, the internal gaskets become brittle or debris gets trapped in the checks.<\/span><\/h3>

      Winter Damage<\/span>:<\/b> If not properly winterized, the internal brass components or plastic modules can crack.<\/span><\/h3>

      Scale Buildup<\/span>:<\/b> Mineral deposits from the water can prevent the device from closing tightly.<\/span><\/h3>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

      How often do I need a backflow test in Surrey?<\/b><\/h3>

      All backflow preventers connected to a potable water supply must be tested once every 12 months<\/b>. Failure to submit your report can result in fines or the disconnection of your water service by the city.<\/p>

      Which cities do you service for backflow?<\/b><\/h3>

      We provide certified testing across the entire Metro Vancouver area, including:<\/p>

      Surrey & White Rock<\/p>

      Langley (City & Township)<\/p>

      Delta & Ladner<\/p>

      Coquitlam & Port Coquitlam<\/p>

      Burnaby & New Westminster<\/p>

      Richmond<\/p>

      Vancouver\u00a0<\/p>

      Tsawassen\u00a0<\/p>

      What happens if my backflow preventer fails the test?<\/b><\/h3>

      Don’t worry\u2014most “fails” are caused by simple debris or worn-out rubber parts. Our technicians can usually clean or rebuild the internal components during the same visit to ensure you pass and stay compliant.<\/p>

      Can I test it myself?<\/b><\/h3>

      No. Backflow testing must be performed by a certified Backflow Assembly Tester<\/b> using specialized, calibrated equipment to ensure accuracy and meet municipal legal requirements.<\/p>

      Keep your water safe and your property compliant.<\/b><\/h3>

      Don’t wait for a notice from the city. Schedule your annual test alongside your Spring Start-up<\/b> for maximum efficiency and peace of mind.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
