Backflow Inspections Sunset Hills

Backflow Preventers are important, and having them be regularly inspected should be part of any home maintenance plan.

Why is a Backflow Preventer Required on a Lawn Sprinkler System?

Backflow valves are required when a house or building is equipped with an irrigation system. Several types of contaminants and chemicals can enter into your irrigation system during its normal seasons of use. Water sits stagnant or trapped in these systems, which leads to a build-up of bacteria and increased mineral content.

When your system isn't operating at full capacity, because of a leak, fire hydrant use, or hydrant flushing etc, this can cause an imbalance in your system. This can cause water from the system to back-up into the drinking water supply. The next time someone runs the water, either for drinking or bathing, it could be contaminated. Even small fluctuations in city water mains that occur due to uneven water use from one neighborhood to the next can cause drops in pressure large enough to cause a back-flow and therefore, contamination to occur.

A little dirt or bacteria backing up into your drinking water may seem innocuous, but there are documented cases of illness and even death from the backflow of contaminated water.

How Backflow Testing is Done - Backflow Inspector Sunset Hills

A backflow preventer is installed in your irrigation system to prevent bacteria and other contaminants from entering your drinking and city water. Our Licensed Sunset Hills Backflow Testers can perform a backflow test to see if there are problems with your Sunset Hills irrigation systems backflow device. To test your system, the water supply is turned off and then the plumbing system and valves are checked to make sure the water is moving as it should. If the relief valve opens, the system may need maintenance. After testing to see if the water is running backwards, the pressure of the water will be checked. If the water pressure rises as the water flows backwards and seems to be struggling, this could mean that the valve needs to be replaced.

Types of Backflow Preventers - Backflow Installer Sunset Hills

There are various types of backflow preventers available for your irrigation system, and the type that is used is determined by what kind of backflow situation you need to prevent in your area.

Three of the most common backflow valves are:

  • Double Check Valves
  • Reduced Pressure Zone Devices
  • Atmospheric Vacuum Breakers

Double Check Valves are typically found in lawn sprinklers and fire sprinklers. There is a ball valve on each end of this device that will prevent backflow. Reduced Pressure Zone Devices are commonly used in areas that a city might deem as having “hazardous” backflow. Every city has a different idea of what is hazardous, so it can vary from city to city. This device includes four valves such as an inlet shut-off valve, two spring-loaded check valves, and an outlet shut-off valve. Lastly, Atmospheric Vacuum Breakers have a valve on the inside of the device that prevents backflow. These systems are based on pressure and are placed 6 inches from where the downstream is for your home.
