What is Backflow Testing and Why do I Need it?

Dior McDonald • Jul 26, 2023

We love to share bits of our knowledge and insights on important aspects of plumbing, so you can keep your systems running smoothly. Below we discuss a crucial yet often overlooked component of plumbing systems - backflow testing.



What is Backflow Testing?


Simply put, backflow testing is a preventative measure that ensures the water in your property flows in the right direction, protecting your home or commercial building from contaminated water.


The importance of backflow testing cannot be overstated. Picture this: you wake up one morning, head to the kitchen, and pour yourself a glass of water. You take a sip, expecting the familiar taste of clean water (well actually, if you live in Perth, chlorine-like pool water, but you get our drift). But what if it tastes different and your water supply has become contaminated due to backflow? This scenario highlights why backflow prevention methods and regular backflow testing services are vital.


Backflow can occur in both residential and commercial plumbing systems, and there are two different types of backflow: backpressure and backsiphonage. The former happens when pressure downstream becomes higher than the supply pressure, while the latter occurs when there's negative pressure in the supply pipes.


Both situations can cause potentially contaminated water from irrigation systems, pools, or even sewage to reverse its course and mix with your potable water supply. Um, that's a hard no thanks.


Understanding the importance of backflow testing is one thing, but ensuring it's done correctly and regularly is another. This is where certified backflow testers come into the picture, like us. Backflow testing is a specialised service that requires technical know-how, precision, and adherence to backflow prevention regulations.


Ensure you Hire Certified Backflow Testers


As professionals in the field, we can't emphasise enough the importance of hiring certified backflow testers. Thanks to 4 years studying plumbing, we are trained to conduct thorough assessments, recognise potential backflow problems, and provide appropriate solutions. We adhere strictly to backflow prevention regulations, ensuring that your water supply system meets all safety standards.



Residential Backflow Testing and Commercial Backflow Testing


In Perth, commercial backflow testing is not just a recommendation; it's a legal requirement. Commercial properties with certain devices and systems, such as fire sprinkler systems, irrigation systems, and commercial boilers, are legally obliged to have their backflow prevention devices tested annually.


While residential backflow testing isn't legally required on a regular basis, it is important to get it done every so often to ensure your water is flowing in the right direction, for everyone's health and safety.
