Why is Backflow Prevention Important?

Backflow is when water that should be flowing away from a property starts flowing in the reverse direction, sending unsafe water into a drinking water supply system. Backflow occurs for a range of reasons but most typically because of back-pressure or back-siphonage.

Examples of potential sources of contamination:

  • Fire hose reels
  • Irrigation systems
  • Swimming pools
  • Vehicle maintenance pits
  • Ornamental ponds
  • Air conditioning towers
  • Vehicle/bin washing bays
  • Chemical injection areas

Backflow prevention is crucial in protecting our drinking water supply from contamination. Install a backflow prevention device to eliminate the risk of backflow at your property. Let our team talk you through your options.

Who Requires Backflow Prevention Device Installation in Brisbane?

If your property is connected to the main water supply, you must have a backflow prevention device installed. Backflow devices are either testable or non-testable. The type you need is determined by the hazard rating of your property or area. Commercial backflow prevention typically requires a testable device.

Salmon Plumbing assists property owners, both residential and commercial, to ensure they meet all backflow prevention requirements. These include:

  • Commercial properties including restaurants and retail
  • Community properties including sports clubs and swimming pools
  • Body corporate and strata buildings including offices and apartments
  • Education institutions including schools and childcare facilities
  • Aged care facilities and funeral parlours
  • Medical and dental facilities
  • Accommodation industry properties including caravan parks
  • Automotive industry properties including vehicle workshops and car washes
  • Residential houses
  • We offer a range of different options and backflow valves to ensure you’re protected. Contact Salmon Plumbing to discuss which backflow prevention device is best for your property.

Backflow Prevention Device Testing and Certification

If your property has a testable backflow prevention device, you are required to:

  • Register the device with the local government; and
  • Have the device inspected or tested annually by a plumber endorsed for backflow testing

Salmon Plumbing is an endorsed backflow tester with extensive experience in installing and testing backflow prevention devices in Brisbane. We’ll inspect your device and provide the mandatory test report to council within ten days.

What are our customers saying about

Salmon Plumbers Brisbane

  • Great work, professional, responsive

    Peter D

    Once again we needed Salmon Plumbing for a upgrade to an existing toilet, They were quick, polite, efficient and helpful with advice.

    Thank you again Salmon Plumbing

    John R

  • Salmon are literal legends and my first choice whenever possible. They’re efficient and thorough, friendly, and affordable.

    I’ve had horrific experiences with a well known company who shall not be named because Salmon were fully booked – and I regret not just waiting longer.

    I’ll always choose these guys first for literally anything and everything in future.


    Toilet plumbing seal replacement, basin pop-up waste. Courtious, careful, neat and tidy

    Warren B

  • Salmon plumbing were able to respond to our request on the same day even though our issue was not an emergency.

    The tradesman turned up on time and fixed our shower pressure issue quickly, as well as installing a new sink waste which we requested while on site. Additionally they fixed an overflow for the sink that had not been installed at all by the builder during renovations. Everything was cleaned up and left tidy.

    Thank you Salmon Plumbing!


    Exemplary experience with a fantastic business. From the owner John, who took my initial enquiry, he was so empathetic after our home was flooded in the February downpour to Gerald who was brilliant in assisting with a temporary system. Virginnia was always wonderful to deal with and kept me up to date and Dan did a fantastic job with the final install and now have a great new system and more importantly a happy wife with hot hot water. Cannot recommend highly enough.

    Jeff D

  • Not only did Chris do an excellent job but, thanks to his initiative, it was completed five days earlier than I’d expected.

    Sue M

    Salmon (and Chris from Salmon), were fast, fairly priced, very open, communicative and friendly; diagnosed a systemic problem and have fixed for a fair price.

    To all the staff and contractors

    We thank you very much for all the work everyone has put in to making our new kitchen come to life.

    We started our journey in mid, October 2020 with a tour of your showroom and with preliminary discussions about what we were looking for in a kitchen.

    Roll on early 2021 and with final sign off of the kitchen plan, demolition and removal of our old kitchen and internal structural redesign, we waited for the new kitchen manufacture and installation.

  • Hi John,

    Just got to say Sebastian has been great today – and everything is spotless!

    I really appreciate good service and I’ve received it every time I have used your company. Thankyou!


    Lyn C

    Dear Claire,

    Thank you for your email and the information contained therein.

    We would like to say how very pleased we were with the professionalism of the young men who attended to this job and ask that it please be passed to your/their Managers.

    Eric is polite yet friendly and took the time to explain what he was doing something we really did appreciate.  Oliver, we understand was still on a learning curve but also very polite and professional.

    Both young men are a credit to your business and should be commended for their professionalism and positive pleasant attitude.  We need more trades personnel and people, especially young people like these two.  Eric should be made an example of how other young men should conduct their trade.  Really top notch.

    We wish you all to continue to be safe.

    Kind regards and thank you again.

    Margaret & Paul Woollard.

  • Thank you,

    Your two plumbers who visited were professional courteous, and good ambassadors.



    David M

    Hey John, just wanted to drop you a line and say Eric did a great job on the house. He was on time, kept me informed and asked all the right questions.

    Things are so strange right now and being without a job I honestly didn’t know what I was going to do. I really appreciate everything you’ve been able to do to make this happen for me.



  • I’d like to say a big thank you to one of your plumbers, Eric. He arrived on time, was a very pleasant young man, friendly and very polite, explained what he was doing, was very efficient.

    Eric is a great asset to your business and I would recommend your company to others who require good service.


    Pat H

    Dear Virginnia,

    Firstly, I would like to thank you for the invoices and secondly, I would like to commend on how pleasant it is to hear your friendly voice over the phone. It certainly makes it easier to ask or clarify questions.

    I would also like to thank Salmon Plumbing especially Sheldon and Mark for their professional service in helping with the blocked ensuite toilet and installation of the hot water system.

    Mark and Sheldon were very patient in answering any queries that I had.

    It was a pleasure to work with you. Thank you very much.

    Warm regards
