Backflow Inspections Glendale

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 must be installed alongside irrigation systems to ensure that each water system remains separate. 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.

There is a water leak in the house, house water service break, city water main break, hydrant flushing, or hydrant use due to a fire, the water pressure in the house or city water mains can drop lower than the water pressure in the system. When this happens, water from your outside system can back-up into your drinking water. The next time you or a neighbor turns on a faucet for a drink of water, the water received could contain contaminants. 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.

Having contaminants and bacteria in your drinking water supply can cause serious illnesses and in some cases can even lead to life-threating diseases.

How Backflow Testing is Done - Backflow Inspector Glendale

A backflow preventer is installed in your irrigation system to prevent bacteria and other contaminants from entering your drinking and city water. Our Licensed Glendale Backflow Testers can check your Glendale backflow tester to make sure that your water supply remains safe. 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 Glendale

The correct backflow preventer for your irrigation system is going to be dependant upon the size of your system, and the types of situations you may face 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.
