Backflow Testing: What You Need To Know

(Last Updated On: August 21, 2017)

Do I Need Backflow Testing?

Backflow Testing is also known as RPZ testing and an essential part of property maintenance! Backflow testing is a requirement of council 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

So you have one of these and know you need a Backflow Test, but aren’t sure of what it does or why it is important? See below:

What does a Backflow Test do?

Backflow testing is conducted to ensure that your backflow prevention device will stop the reverse flow of water from unsafe sources into your drinking supply system.  To explain it simply, backflow testing is designed to check your backflow devices are working properly and keeping your drinking water consumable.

Why is Backflow Testing Important?

Is your Backflow prevention device is working correctly? If it is, there will be clean drinking water supplied to your property with no contaminants. However, if it is not working well, contamination of your drinking water will occur, ceasing your ability to drink the water going to your property. Hence it being important to ensure you have regular backflow testing to prevent the contamination of your water.

Whilst this is not a common occurrence, it is a problem you want to avoid without fail!

It is also important to note that backflow only occurs when the water delivery main is at a lower pressure than your plumbing system. This will happen when there is an increased demand for water or when your property has ruptured or burst mains. Despite this, it is still a requirement to ensure that your backflow prevention devices are maintained and in working order.

Rather than fixing such a sever issue, we reccommend maintaing and preventing this from occuring by inspecting, testing and repairing your Backflows.
