Keep Your Water Clean with Backflow Protection
Looking for professional backflow prevention services in Perth? Backflow might not be something you think about every day, but it matters. It happens when dirty or contaminated water moves the wrong way through your pipes and into your clean water supply. That can cause serious health problems and damage to your plumbing. At Houseworks Plumbing & Gas, we install and test backflow prevention devices for homes across Perth. We make sure your water stays safe, clean, and up to code. We also offer emergency plumbing, blocked drains, and hot water systems services across Perth.
How Backflow Starts
Backflow usually begins with a sudden drop in water pressure. When that happens, it creates a small vacuum in the system that can pull used or contaminated water backward into clean lines. This can happen if there’s a broken pipe, high water use nearby, or during firefighting activity.
Faulty plumbing design can also cause cross-connections—places where clean water lines and potential contaminants meet. Garden hoses, pools, or irrigation lines connected without the right protection are common risk points. Once contaminated, your home’s water can quickly become unsafe to use or drink.
Where Backflow Risks Hide
Many setups around your home can create a backflow risk if not protected. These include outdoor taps with connected hoses, garden irrigation systems, spa baths, pool connections, and even indoor appliances like dishwashers and boilers. If any of these features don’t have the right safety measures in place, they can push dirty water into your drinking supply when pressure drops.
You won’t always see backflow when it starts. That’s why prevention is key—not just after something happens, but before.

What a Backflow Device Does
Backflow prevention devices keep water moving in one direction—into your home, not back out and in again. These devices include valves and air gaps, depending on how your system is set up and how much risk exists.
There are several types of devices we may use:
- Air Gaps: Spaces between taps and fixtures so water can’t be pulled back into pipes
- Double Check Valves: Often used for low-risk areas like small irrigation setups
- Reduced Pressure Zone Devices (RPZs): Used for higher-risk areas with strong contamination potential
We assess your setup to find the right device and install it to meet safety and legal standards.
Why Licensed Installation Matters
Only licensed plumbers can install or test backflow devices. These systems must meet strict regulations set by the Water Corporation and local councils to stay safe and legal. At Houseworks Plumbing & Gas, we’re fully licensed and know Perth’s local rules inside and out.
We take care of the full process—checking your system, choosing the right device, installing it properly, and completing all testing. We even handle the paperwork and submit any reports to the right authorities so you don’t have to.
Custom Solutions for Perth Homes
No two homes are the same. That’s why one-size-fits-all doesn’t work for plumbing safety. We adjust our backflow prevention systems based on how your property is used. Got a pool, garden setup, or new extension? You need a prevention device that matches that layout and potential risk.
We’ve worked across Perth’s many neighbourhoods, from suburbs near the coast to growing urban areas. We understand soil conditions, water pressure patterns, and common household setups. With Houseworks Plumbing & Gas, your system gets protection that works whether you’re in older Fremantle homes or newer builds in Ellenbrook.
Make Backflow Testing Part of Your Routine
Even the best backflow devices need regular checks. Over time, valves wear out and buildup collects inside the parts that keep water flowing the right way. If it fails, you may not notice anything until it’s too late. That’s why we offer scheduled inspections and annual testing where required by law.
Our licensed plumbers run full pressure checks, inspect components, and look for any issues that could lead to water contamination. We provide full reports so you can keep your records or submit them to your local council. We remind you when your next check is due so staying compliant is easy.
