With a huge amount of harmful chemical contaminants around us, it is challenging to ensure a safe supply of water in today’s world. Industrial or commercial units require water for many purposes, for instance, medical, dental, food processing, municipal water supply and others. In such cases, if the water gets contaminated, it can cause a huge amount of damage. This is where backflow preventers can help in preventing contamination of water. If your commercial property lacks a backflow preventer, you should know that a backflow preventer system can make a world of difference. And it is essential for a commercial unit, for you are directly related to the public’s well-being. That is why commercial plumbers recommend commercial units to integrate their water piping system with a backflow preventer. Read the blog to help you understand the importance of a backflow preventer.

What is a Backflow preventer?

A backflow preventer is a mechanical device that helps to prevent the backflow of water that can occur in the piping system of your property. The backflow of water can also be prevented with an air gap, which eliminates probable cross-connection or offers a physical break to prevent the backflow.

What is backflow and how does it occur in the plumbing system?

Before proceeding further, you should know what backflow means? The backflow of water takes place when water flows in the reverse direction and enters back into the pipe supplying potable water. Such a scenario can become serious if the water that backflows contains harmful chemicals, bacteria or pollutants, and can contaminate clean water.

There are two types of backflow conditions:

  • Backpressure condition: This condition occurs when a property’s water system is at a higher pressure in comparison to the supply system of the potable water. Such a situation can force the unwanted water to enter into the supply pipe of potable water. Many situations can trigger such pressured imbalance, for instance, potable water system connections for boiler systems.
  • Backsiphonage condition: This condition occurs when a negative or very negligible pressure is present in the water supply system of the potable water. The condition can trigger unwanted water to get sucked into the potable water supply system. The causes of such conditions can be several like low main pressures due to excessive withdrawal of water for water main flushing or firefighting.

How does backflow prevention help?

Installing a backflow prevention system can help prevent any such condition that leads to the backflow of unwanted water into the potable water supply system. The backflow preventing devices are designed to allow unwanted water to flow out of the property and snap shut the moment wastewater flows back up the potable water pipes. An installed backflow prevention system will ensure a safe supply of clean and potable water and help you stop worrying about any uncontrollable factors that trigger such situations. For proper installation in commercial properties, it is essential to hire plumbers in Mandurah who have the right experience and have the know-how of how to install and maintain such a system.


A backflow prevention system can prevent factors that reverse the direction of unwanted water flow and stop it from contaminating potable water.
