Backflow Inspections Winchester

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. Many different chemicals are used to keep a lawn in excellent shape, and these chemicals can sometimes find there way inside your irrigation system. These systems can sit still for days, and water that isn't moving can collect tons of different bacteria and contaminants.

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. 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 Winchester

A backflow preventer is installed in your irrigation system to prevent bacteria and other contaminants from entering your drinking and city water. Our Licensed Winchester Backflow Testers can perform a backflow test to see if there are problems with your Winchester 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 the water direction is checked, the pressure of the system will then be measured. 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 Winchester

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.
