What is backflow?

Backflow TestingBackflow is an unwanted reverse flow of contaminated water into the main pipeline or plumbing system from a residential or commercial plumbing system. Cross-connection occurs when the contaminated water comes in contact with the main water supply. To prevent a cross connection, the correct backflow prevention devices must be installed. Cross contamination is extremely hazardous to the main supply of water, so this is immensely important.

Our backflow prevention services include:

  • Supply and installation
  • Testing and certification
  • Valve protection / vandal deterrents
  • Maintenance and repairs
  • Audits and reports

Backflow Testing Sydney NorthAnnual testing services

Pure Plumbing Professionals can take care of all your testing and certification requirements. All backflow prevention devices are required to be tested and certified annually. We can also lodge documentation with the relevant local authority. Maintenance or repair work is also performed if required.

Hazard rating of sources

The hazard rating of the source of contamination will determine the kind of backflow prevention device required. For instance, a hose tap located in a rubbish bin washing bay on a commercial or industrial property has a high hazard rating, therefore an RPZ backflow device will be needed. On the other hand, a residential property with an underground rainwater tank connected to the water supply has a medium hazard rating so it will require a double check valve. We can advise you on the required backflow prevention device depending on your hazard rating.

Devices for protection from potential contamination sources

  • Irrigation systems
  • Vehicle washing bays
  • Fire hose reels
  • Fire systems
  • Cooling towers
  • Grease traps
  • Rubbish bin washing bays
  • Chlorinators
  • Underground rainwater tanks
