Backflow Prevention?
Ever heard the term backflow prevention?
Some people may already be knowledgeable in backflow prevention; however, for those who haven’t explored the term, it’s time to look into this plumbing element.
Everyone has a water system running through their property, which is shared amongst others, and keeping this water flowing appropriately is extremely important. If water becomes contaminated, this can affect the supply of drinking water and, hence, cause a major outbreak of sickness. Our plumbing systems are built to regulatory standards to ensure the water is at no risk of contamination, and a part of the prevention elements is backflow prevention.
Every property has different risks with plumbing systems, and backflow prevention will be adjusted depending on many factors. However, your risk of backflow is calculated through different categories that indicate how often the system needs to be checked.
Licensed Plumber
Your risk category can be assessed by a licensed plumber, who can then suggest the right backflow prevention device. All plumbers are bound by Australian Standards when it comes to backflow prevention, meaning you don’t need to worry about whether your plumber is going to provide you with the correct device.
Backflow, by simple definition, is when the flow of water is turned back in the other direction, which causes a reverse pressure.
- If the water flows backwards, this can be because of a few different issues with the water pressure:
- If you are using water at an increased level, higher than that supplied by your water utility company
- If there is some sort of break in the water main that’s supplying you with water (causing siphonage)
- Heavy use of water from the main system
In order to prevent this backflow from occurring, as mentioned above, there are specific backflow prevention systems. Backflow systems include check valves, which relieve back pressure, and also air gaps in the system. Your air gap examples could simply be the gap between a sink rim and a wall mount.
Hopefully, with the basic information, you can have a greater understanding of hee term ‘backflow prevention’ and how it affects you when it’s not in working order. It’s best to understand plumbing terminology as best you can to ensure you are always on top of all potential issues.
