Backflow prevention
Backflow occurs when water flows backward through your plumbing system, potentially allowing contaminated water to enter the clean water supply. This dangerous situation can happen during pressure drops from burst mains, high water demand, or fire-fighting operations. Professional backflow testing ensures your prevention devices are working correctly to protect your water supply.
We provide comprehensive testing and certification services to keep your property safe and compliant.
Expert backflow testing services
Our accredited backflow plumbers deliver thorough testing services that meet all regulatory requirements. We handle everything from annual compliance testing and new installations to emergency repairs and council documentation. Every backflow prevention device receives detailed attention from our experienced team.
Your property will maintain the highest standard of water safety.
Hazard ratings
Your property's required level of backflow protection depends on its specific hazard rating. High hazard properties, such as chemical processing facilities, industrial sites, and medical facilities, require the most robust prevention systems due to serious health risks. Medium hazard locations including commercial buildings, irrigation systems, and swimming pools need reliable protection against moderate contamination risks. Even low hazard properties like standard residential homes require appropriate backflow prevention measures to maintain water safety.
Professional backflow prevention installation
Our licensed plumbers begin with a thorough assessment of your property's specific needs before recommending and installing the most appropriate backflow device.
Whether your property requires a Reduced Pressure Zone Device, Double Check Valve, or simpler solution, we ensure every installation meets strict safety and compliance standards.
Certified Annual Testing
For properties with medium or high hazard ratings, annual backflow testing isn't just recommended - it's mandatory. Our comprehensive testing process includes thorough device inspection, precise pressure testing, and complete valve operation verification. We handle all documentation and council submissions, ensuring your property maintains full compliance with current regulations.

About backflow testing
What is backflow testing and why is it important?
Licensed plumbers conduct annual testing to ensure these devices function properly, particularly in properties with irrigation systems, fire sprinklers, or industrial processes. This testing is mandatory for many properties and helps maintain the safety and quality of the drinking water supply.
How often should backflow testing be conducted?
Professional plumbers maintain detailed records of all tests and can establish appropriate testing schedules based on your property's specific requirements. They'll provide reminders for upcoming tests and maintain documentation of compliance for property owners.
What happens during a backflow test?
The testing process includes visual inspection for damage, operational testing of all moving parts, and pressure testing to verify proper function. Detailed records are maintained, and test results are submitted to relevant water authorities as required by regulations.
What types of properties require backflow prevention?
The level of protection required depends on the hazard rating of potential contamination sources. Professional plumbers can assess your property and recommend appropriate backflow prevention measures based on current regulations and risk factors.
What happens if my backflow device fails testing?
Property owners must address failures promptly to maintain compliance with health regulations. Professional plumbers can handle all aspects of repair or replacement, ensuring your system returns to full compliance quickly and efficiently.
Can I test my own backflow prevention device?
Certified testers use specialised equipment and follow strict procedures to ensure accurate results. They maintain current certifications and stay updated with changing regulations and testing requirements.
What documentation do I receive after testing?
Professional plumbers submit required documentation to water authorities and maintain records for future reference. They can also provide maintenance histories and testing schedules to help property owners maintain compliance.
How do I maintain my backflow prevention device between tests?
Professional plumbers can provide maintenance guidelines specific to your device type and usage patterns. They recommend reporting any concerns promptly to prevent potential problems and maintain system effectiveness.
What are the consequences of not conducting regular backflow testing?
Property owners may face fines, legal issues, or service interruptions for non-compliance. Professional plumbers can help establish proper testing schedules and maintain compliance, protecting both public safety and property owners' interests.

What people say about After Hours Plumbing
Nathan is actually a god send!! He rocked up to our place at 10pm at night, work his butt off then came back to our place at 12pm the next day and continued to work his butt off to get the new pump up and running. He has excellent communication and thoroughly documented everything he did and recommends to ensure this doesn’t happen again. He is my top top top plumber recommendation in the area. If you have any problems he will be there day or night!!
We have used Nathan now for a number of jobs on our properties, and in all cases (especially those emergency call outs) Nathan was prompt, professional and always on top of what was required to get the job done. He is also very knowledgeable on spotting issues that may come up later down the track and ensuring you are aware of any potential problems and how to look out for them. Highly recommended for all your plumbing needs
Nathan was an absolute life saver! Responded and came quickly to a late night job and worked hard to identify and fix the problem! He documented and explained everything that he was doing as well as being super friendly. He did an excellent job and went above and beyond. I can’t recommend him enough!!
Nathan installed new shower heads and faucets in my two bathrooms. He was so quick and the work was done skilfully. Couldn’t be happier with the work and wouldn’t hesitate to call him again for any plumbing jobs I might need in the future
Nathan from After Hours Plumbing is excellent. I have used him both privately and also engaged him as recommended plumber to all our landlords. He is efficient, professional and prompt at attending.
Nathan was very professional in all dealings with our hot water replacement. The job was completed quickly with no problems. Highly recommend for all plumbing service or replacement needs.
Twice we had Nath Schofield to do our projects. One to fit an outdoor sink for my outdor kitchen and next to fix the irrigation system for our garden. He did an amazing job and I highly recommend his services to anyone. He is very professional, knowledgeable and you will be very happy & contented with his neat work.
I am very happy with Nathan’s quality work and his service. He was incredibly prompt, arriving shortly after I reached out about a pipe leakage issue in my house. His customer service was top-notch, he kept me informed every step of the way, explaining the process and ensuring I understood what needed to be done. Not only did he fix the pipe leakage with diligence and great attention to quality, but he also helped me with my kitchen tap while he was here and resolved it on the spot! Additionally, he provided me with a reasonable quote for replacing my aging hot water system, which I’ll definitely consider in the near future. I highly recommend Nathan for anyone looking for professional, reliable, reasonable and efficient plumbing services. Great work Nathan!

We had a backyard leak in our irrigation piping on a Saturday late afternoon. Nathan replied less than a minute after I texted him and arrived at 7:30 the next morning to fix our issue, so we had to go only one night without water. So happy with our service.
I would recommend Nathan in a heartbeat. He has done a few jobs for me now and I've found him to be extremely trustworthy and very friendly. He is responsive, quickly diagnoses the issue and explains the work required in an easy to understand way. His pricing is fair and it's clear he knows his stuff with extra qualifications to provide a more comprehensive plumbing service. I will definitely continue to use Nathan in the future.
