What Are Backflow Preventers and How to Know If You Need It?

What Are Backflow Preventers and How to Know If You Need It?

The "backflow preventer" is aptly named, succinctly summarizing its job. There are many types of backflow preventers, but they all work to keep the water line flowing in only one direction. In this article, we will review some of the common types of backflow preventers and go over some reasons why you might need one. If you are experiencing trouble with your existing backflow preventers and need a plumber, then call Rooter Hero Plumbing to schedule plumbing service or a plumbing repair today. Our live representatives are on standby to take your call.

What Is a Backflow Preventer?

Let’s break this down into two parts. First, what is backflow? Clean, potable water travels through a long connection of pipes before getting to your faucet or showerhead. If this water stands still for too long, it can become a cesspool of bacteria and other contaminants. If that same water flows in multiple directions, you have a mess on your hands. A backflow preventer keeps water flowing in one direction so that your water is not tainted. For instance, it keeps the sprinkler system’s water contained in its specified area and prevents that water from coming out of your kitchen faucet. Fortunately, backflow preventers are reliable and there are a few types.

The Types of Backflow Preventers

Let’s start with the double-check valve. These are designed to keep chemicals and toxic substances out of the water supply line. As the name gives away, these backflow preventers utilize two check valves to monitor and control the water supply. The second check valve offers insurance in case the first gets stuck open. The double-check valve makes it easier for technicians to test equipment and check whether the backflow preventer is operating properly.

Next up we have the pressure vacuum breakers. These are usually used with lawn sprinkle systems to keep the dirty sprinkler water from reaching your drinking water. Pressure vacuum breakers are easy to assemble and disconnect, usually mounted close to an exterior wall or within a recessed underground box.

Finally, there are the reduced pressure zones assemblies. These are similar to double-check valves in that they both offer an additional check valve for added security. Reduced pressure zones, however, also feature a valve that is engineered to release contaminated water from the system.

Do You Need a Backflow Preventer?

As you can imagine, the backflow preventer has a lot to offer your plumbing system and your health. Not everyone has money to spend on plumbing installations though. So, do you really need a backflow preventer? Here are some signs of a broken backflow preventer:

  • Discolored or cloudy water
  • Water leaks
  • Slow drainage
