The necessity of backflow testing and prevention services

backflow prevention testing procedureIt is mandatory to have backflow prevention systems checked and tested every 12 months to prevent risk of water contamination. Businesses have the responsibility to install and test their backflow prevention assemblies, and to ensure that their respective backflow device is working and well-maintained. Neglecting this responsibility may cause contamination and result in a variety of illnesses. Other reasons why businesses need water backflow prevention include:

  • Not having a backflow prevention device is dangerous. The petering out of clean water supply due to cross-connections has the potential to allow contaminants into the drinking water system that, if consumed, can predispose you to develop gastrointestinal illnesses such as diarrhoea, vomiting and abdominal cramps.
  • Liabilities from backflow problems are expensive. Imagine the numerous medical bills that companies need to pay yearly due to contaminated water.
  • A water filter is not enough to prevent water contamination. A water filter acts as a physical barrier against water impurities but isn’t always enough to have consistently safe drinking water. With the installation of a backflow valve, it empowers the anti-water contamination function of water filters by preventing water pollution due to backflow. Backflow prevention testing then ensures your valve is doing its job properly.
