Prevent Water Backflow Whenever Possible

No One Wants Water Backflow

Water systems can have issues and malfunction for a variety of reasons. When water backflow occurs, it is downright gross and also can be harmful. It’s important to prevent backflow when at all possible so you can avoid the issues that can arise from it.

What Is Water Backflow?

Water backflow describes what happens when the water flows in the other direction from the intended course. Instead of taking dirty water away from your house, for example, that water comes back into  the house and can contaminate the drinking water. There are two main types of backflow:

Back Pressure

Back pressure water backflow takes place when the pressure in the drinking water system within a house is larger than the pressure in the public water lines. This could occur because of an increase in the downstream pressure or a reduction in the house water lines. If firefighters are using the water mains, for example, it’s a good cause of this.


This occurs when negative pressure builds up within a water system. The concern here is that the pressure can draw contaminated water into the house and the drinking lines, like you would water in a straw.

Backflow Preventers

Since it’s best to prevent backflow from ever occurring so your water is clean and healthy at all times, you might want to hear more about backflow preventers and how they can detect and then correct issues that could turn into backflow problems. Backflow preventers can help with back pressure and siphonage problems.

The Back Pressure Conditions

If there are leaks, the preventer will signal a relief valve to open. If there’s debris in the way, the preventer notices the pressure changes and signals the relief valve chamber to equalize and open, if needed. The relief valve can also let contaminated water out if it starts to backflow, before it reaches your home.

The Back Siphonage Conditions

If debris enters the upstream, the preventer will notice and release leaking water through a relief valve. There are also valves that close to prevent downstream water from getting back into the system and becoming upstream water. These preventative measures can help the water line remain clean for use inside a home.

Do You Want to Prevent Water Backflow?

You may not always notice when water backflow occurs. Sometimes, it is obvious. Other times, it sneaks up on you, contaminates your water, and simply goes away without you knowing. Either way, it can lead to serious health concerns and it’s not something you want happening in your house.
