Access to clean potable water is a valuable asset. Water is the most vital resource of the world and having to deal with contamination shouldn’t deprive us of it. There are many ways to ensure our water remains pure and uncontaminated, but one of the easiest and most effective ways is by learning about the efficiency of backflow devices. It is needless to say that prevention is not an issue, but our lack of knowledge regarding techniques that proactively prevent water from backing up can disadvantage us.

What is Backflow?

Backflow occurs when impure water reverses its flow and starts to flow in the direction of the clean water, where it then mixes into the water supply line and creates a health hazard. The water system has a point known as a cross connection, which is where potable water is connected to non-potable water but divided with a separating device known as a backflow preventer. There are many reasons that cause the backflow of water but the two most common ones are as following:




• Back Pressure – When high-pressure fluids flow in the areas of low-pressure fluids, back pressure is said to have occurred. This can be triggered by a number of factors such as an increase in boiler temperature, and pumps in a water system. Also, pipes with direct cross-connections are ultimately susceptible to back pressures.

• Backsiphonage – Backsiphonage occurs when higher-pressure fluids are drawn into lower pressure areas. With a drop in pressure in a water system, fluids contaminated with chemicals and other hazardous materials get pulled into the water supply, which results in water main breaks or where a high use of water is made, usually by fire hydrants to put out fires. Pipes with indirect cross-connections are susceptible to back siphonage.

To avoid the lethal consequences of backflow causes it is necessary to install and maintain efficient backflow devices.

Backflow Preventers

A backflow preventer is a device that is designed with several components, each that serves its own purpose. It is designed to prevent the reverse flow of water and safeguard potable water supplies. These devices are installed at many points in a water system, but most importantly at cross-connections between the repositories.




They function manually and automatically and are mostly dependent on optimal pressure. An optimum pressure determines the efficient operation of a backflow device, and hence factors that disrupt these pressures must also be inspected from time to time by professional plumbing and drain cleaning services in your area.

For residences, your need for a backflow device depends on how your water supply is regulated. If you have an in-ground irrigation system, it is imperative you install a reverse flow preventer. When it comes to commercial properties, it’s a different story: the types of commercial backflow preventers vary in complexity.

Call a Professional Plumber

It is always a wise idea to call a professional plumber to carry out the installation of a backflow device. Especially, considering the fact these devices are complicated to install post house construction. They require precise installation methods executed with skill by an experienced plumber, and there are several steps necessary to ensure the preventer is installed safely and legally.

Don’t let dirty water make its way into your home or business. Now that you know a little more about backflow, it’s up to you – and your plumber – to make sure you never experience it.
