Backflow Prevention Device: How It Protects Water Pipeline

Have you ever heard of a backflow prevention device? Yes, there is a device that can prevent the drainage to flow back. Wondering why would the drainage flow back? Well, sometimes, due to rainfall, storms, or some disasters earth can be unstable, at least for the ground under your house. During these times, the drainage system can break, pipes can burst and sewage overflow can happen. All these things may result in the backflow of the sewage causing problems at your house. That is why a backflow prevention device is used.

What Is A Backflow Prevention Device?

It is a device installed on the water pipes in your home. This device allows the flow of water only in one direction and not the other way round. It is made with only one purpose: not to mix drinking water with that of the sewage water and not to contaminate the water in any way.

When water flows in through the main supply, it should only flow in your home. But due to some pressure changes, it can flow backward too. This backward flow will then get mixed with the main supply itself. This usually happens when there is a break in the main supply line where the pressure is lost. As the water is no longer pushed to your house due to loss of pressure, it will move backward. Now, contamination of water occurs with human waste, minerals, soaps, fertilizers, etc. this is where the backflow prevention device works.

How Does A Backflow Prevention Device Work?

A backflow prevention device is installed on a water pipe. Now, after installation, it allows only one direction flow of the water. It acts as a one-way gateway that allows the city’s drinking water supply to reach your house’s pipelines. It stops the water then and there it tries to flow backward into the city’s main water supply. 

No matter where you live or is it necessary to install this device or not, we anyhow recommend you to get it installed. Because you might not know when the incoming good quality water and wastewater will get contaminated through pipes. It is better to have a backflow prevention device that keeps your water pure and fresh without any contamination. 

As we know, a backflow prevention device is made to protect your potable water supplies from being contaminated. The working of this device depends on the water distribution system of the city. A significant pressured water is passed on to other pipes through taps, showers, and other appliances. When the main water tank bursts, pipe freezes, and breaks, or demand for water supply becomes high, the pressure of the water reduces. Due to this reduction of water pressure, pipes may allow the soil, minerals, and other sources of waste to enter. This is again sent back to the main water supply. This return of the contaminated water to the main supply is stopped by the backflow prevention device.

  • If you are concerned about the safety of your home or business, then you should know that there is an easy way to test for backflow.
