Your irrigation system is a vital component of your lawn’s health. However, they can backflow and result in contaminated water entering into your home’s supply of drinking water if a backflow preventer is not installed. While there are some building codes that require the systems are protected with these devices, this isn’t always the case for homes. However, it is still a good idea to have one installed.

How Common are Backflow Events?

While you may not hear about the situation often, backflow issues do occur from time to time. In the U.S. there have been several cases of injury, illness and even death that have resulted from the backflow of hazardous and toxic substances. The good news is, protecting your home, family and drinking water is actually quite simple. Even if your irrigation system was installed without a backflow device, one can be installed now, to prevent the possibility of contamination.

What Exactly is Backflow?

Just like the name of the event implies, backflow occurs when water moves the wrong direction and into your water supply instead of out of it. When backflow occurs with your irrigation system, it can result in pesticides and other chemicals to enter into your water line. If this occurs, you may wind up drinking the fertilizer you use outside.

What Causes Backflow Situations?

Water naturally wants to move from an area with high pressure to an area of lower pressure. The issue of back-siphonage may result if the water pressure in the line is reduced, when there is a broken water line if a large amount of water is being used, like what is needed for fighting fires. If the sprinkler system is not installed properly, then backflow may occur because there is excessive amounts of back-pressure coming from the pump.

How Does a Backflow Preventer Help?

This device, which is also referred to as an air gap, will stop water from moving back into the water supply line. It makes sure that the sprinklers are a one-way system, which ensures the drinking water remains contaminant free. The most common types are the pressure vacuum breaker, the reduced pressure and the atmospheric vacuum breaker.

Are Backflow Preventers Required?

There are certain areas in Kansas where backflow preventers are required; however, they are highly recommended regardless of where you live. It is a good idea to get to know the rules and regulations for your area to ensure you meet the requirements.
