Backflow Systems – Testing, Installation & Repair

Backflow system

Why must the backflow system be inspected & tested?

Because backflow assembly parts can break down and wear out, municipalities in the lower mainland have created by-laws to help ensure the safety of our drinking water. By having the backflow tested
annually, you will help to ensure the drinking water supplied to your home remains safe.

Terms:

  • Backflow happens when there is an undesirable reversal of flow in a potable (drinking) water distribution system; this occurs because of back-siphonage or backpressure.
  • Backpressure occurs due to a condition that creates pressure in the non-potable piping system greater than the pressure in the potable water system. Example: gravity can cause backpressure, due to the elevation differences.
  • Back-siphonage┬áis a form of backflow due to a negative or sub-atmospheric pressure within a potable water system.
