Backflow Prevention & RPZD Testing

G.F. James Plumbing offers professional backflow prevention, compliance and RPZ device testing services to commercial clients in and around Sydney. Our fully licensed and insured plumbers are trained to efficiently detect your risk of backflow, advise you on the best backflow prevention measures, and make sure your existing measures are compliant with the highest industry standards.

What Is Backflow?

Backflow is when water from a property starts flowing backwards into council water pipes. It usually occurs when:

  • There is a drop in the pressure main
  • Water pressure at your property is higher than at the main

Backflow can cause possible health risks because of contaminants polluting the water supply. To this, it’s important for every property to put in place industry compliant backlog prevention measures.

Expert Backflow Prevention Measures

At G.F. James Plumbing, we have a major focus on water and plumbing safety, especially with commercial plumbing. That’s why we offer expert backflow prevention, Reduced Pressure Zone (RPZ) device testing and industry compliance. Our accredited backflow plumbers will efficiently inspect your plumbing system to determine your backflow risk and assess your need for a backflow prevention device. They will then install an RPZ device, conduct routine tests and lodge the results with Sydney Water.

What Is an RPZ Device?

An RPZ device is a valve that prevents backflow and back-siphoning from occurring in your plumbing system. It is only installed in properties where there is a high risk of backflow, is compliant with council regulations and can conveniently be tested to ensure efficiency.

Book Accredited Backflow Prevention Services

All commercial properties in Sydney, especially those with onsite manufacturing or chemical usage, are required to have an accredited backflow plumber assess your site and install all necessary backflow prevention measures. If you have a water meter that is larger than 25mm, a fully qualified backflow plumber will need to install and regularly test your RPZ device.

At G.F. James Plumbing, our plumbers have more than 40 years of experience offering commercial and industrial plumbing services, and are fully accredited backflow plumbers. Contact us and call 02 9649 1099 to learn more about our backflow prevention services and book an appointment today.
