Backflow Testing: What You Need To Know

(Last Updated On: June 7, 2018)

Do I Need Backflow Testing?

Backflow Testing is also known as RPZ testing and is an essential part of property maintenance! Backflow testing is a requirement of council for property owners that 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? Read on:

 

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.  Backflow testing is designed to check that your backflow devices are working properly and keeping your drinking water consumable.

Why is Backflow Testing Important?

Is your Backflow prevention device 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. This impacts your ability to drink the water on your property. Thus, is is important to ensure you have regular backflow testing to prevent contamination.

Whilst this is not a common occurrence, it is a problem you need 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. Therefore, it is an important requirement to maintain your prevention devices, ensuring if something goes wrong, there is a safeguard.

How often should I get my Backflow Device Tested?

Your backflow device should be tested at least once each year. The device must be inspected or tested by a person who is licenced to do the work. RTL Plumbing provides this service. It’s worth noting that it is a requirement under the Plumbing and Drainage Act 2002 that owners of installed testable backflow prevention devices must register the device with the local council.

 

Rather than fixing such a severe issue, we recommend maintaining and preventing this from occuring by inspecting, testing and repairing your Backflows. RTL Plumbing provides a complete and thorough backflow prevention service which includes inspection, testing and repairs.
