A backflow preventer is a device that’s installed in your home’s water pipes that lets water flow in one direction but never the opposite direction.
There are so many different plumbing appliances in our homes and commercial properties, and it can be hard to keep track of them. From your toilet to your dishwasher, it’s hard to understand exactly what their overall functions are. And if you’re here, then you must be wondering what a backflow preventer is? You’ve come to the right spot. A backflow preventer is a device that’s installed in your home’s water pipes that lets water flow in one direction but never the opposite direction. Its sole job is to prevent your drinking water from contamination due to backflow. But what exactly is “backflow” and how does it occur? Is it something you should be worried about as a home or business owner? No need to worry, we will answer these questions and more. Here is a guide to your plumbing system’s backflow preventer.
How Does “Backflow” Occur in the First Place?
When water enters your house from the main water supply line, it should only be flowing in once direction: inside your home. But sometimes, because of pressure changes in the pipes, the water can flow backward and seep back into the main water supply line. For example, backflow can occur when there has been a break in the main water line or when a fire hydrant is opened up for use. Because pressure is lost during these types of events, water is no longer being pushed forward into your house and will flow backward into the city water lines. When this occurs, you need a backflow preventer to stop contamination into the waterline.
How a Backflow Prevention System Prevents Backflow
Backflow prevention systems are devices that are installed onto a pipe that only allow water to flow into one direction. Think of if it as a one-way gate that lets water from the public water supply to flow into your home’s piping, and stops water if and when it ever tries to flow backward into the public water supply.
How To Know if I Need a Backflow Prevention System Installation
First off, anyone who has an irrigation system or a well is required by law to install a backflow preventer around the water meter. This is because both systems are at risk of contamination due to backflow. Even if you don’t have an irrigation system or well, it is still recommended to install a backflow prevention device in your home. Call B&D Plumbing for any questions you may have!
