Backflow Testing: What You Need To Know

Also known as RPZ testing and an essential part of property maintenance, backflow testing is a council required test that must occur annually for property owners if they have any of the following:

  • An irrigation system
  • Fire hose reels or hydrants
  • A commercial or industrial activity or machinery connected to the mains
  • Water outlets in proximity to pollutants, grease traps or chemicals
  • An underground rainwater tank that has mains water backup

Now you’re probably asking “what is backflow testing and why does it matter?” and that is a very good question. A backflow test is conducted to ensure that your backflow prevention device stops the reverse flow of water from unsafe sources of water into a potable (drinking) supply system. Put simply, backflow testing is designed to check if the backflow devices installed on your property are working properly, thus ensuring that the drinking water supplied to your property can not be contaminated by any other connection from your property.

Far from a common occurrence, backflow can only occur when the water delivery main is at a lower pressure than your plumbing system. This may happen when there is an increased demand for water or when there are ruptured or burst mains. Despite this, it is still a requirement to ensure that your backflow prevention devices are maintained and in working order.
