At Think Water Canterbury proper maintenance of backflow preventers and cross-connect systems is vital to ensuring the safety of the your drinking water system.
Backflow is an unwanted reverse flow of contaminated water into the main pipeline or plumbing system from a residential or commercial plumbing system. Cross-contamination will occur when the contaminated water comes into contact with the main potable water supply. To stop a cross connection a suitable backflow prevention device needs to be installed. Cross contamination is extremely hazardous to the main supply of water, so this is extremely important to be done correctly.

Some properties that may require a backflow prevent test include:
Think Water Canterbury can look after your testing and certification requirements. Each backflow prevent device is required to be tested and certified annually or after any repairs have been done to the pipework. We can also prepare the documentation to lodge with the local council. Maintenance or repair work will also be carried out if required.
The hazard rating of the source of contamination will determine what type of backflow preventions device is required. For example, a hose tap that is located in a trash bin washing bay on a commercial or industrial property has a high hazard rating, therefore you will need to install a RPZ backflow device. Another example is a residential property that has a rainwater tank below ground which is connected to the water supply will need a medium hazard rated device which could be a double check valve. Think Water Canterbury can advise you on the required backflow prevention device depending on your hazard rating.
