Backflow Prevention


Backflow occurs when the water in a pipe is forced to flow in reverse, this can be potential fatal. PPS have certified plumbers to perform the regulatory testing requirements to ensure your water supply remain safe.


A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened). Reduced pressure in the pipe may allow contaminated water from the soil, from storage, or from other sources to be drawn up into the system.

backflow prevention in action...

how do we prevent it?

First, you should understand that water contamination can be life threatening. Remember that many cases of contamination have been linked back to poorly maintained backflow prevention valves.
Plumbing & Pipeline Solutions will help prevent it by fitting a device that stops the reverse flow of possibly polluted water. We will do all the installation, servicing and testing of backflow prevention devices. Lastly, the government legislation requires regular certified testing of all backflow prevention valves.

Where submerged mains inflow is permitted, a backflow prevention assembly is required, which protects the potable water system from contamination hazards. A check valve is a basic form of backflow prevention, but often more complex devices are required because check valves are not considered to be reliable, when compared to more sophisticated devices with redundancies and reduced-pressure zones.

In South Australia approved backflow prevention devices are required by law and must be installed in accordance with plumbing standards. A typical backflow assembly has test cocks and shut-off valves, and must be tested when installed, if relocated or repaired, and on an annual basis.
Plumbing & Pipeline Solutions have licenced maintenance plumbers that can meet all your backflow prevention requirements including installation, annual testing, and repair. The backflow prevention cost for not maintaining the devices correctly can be fatal so with that, Plumbing & Pipeline Solutions are able to make this part of your regular maintenance schedule.
