Backflow Inspections Clayton

Just like any other system connected to your water line, backflow preventers will periodically be needed to be inspected to ensure they are safe.

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. Contaminants can enter an irrigation system from fertilizer or pesticides that are sprayed onto lawns. These systems can sit still for days, and water that isn't moving can collect tons of different bacteria and contaminants.

During a system imbalance, which can happen during a water main break, the use of a fire hydrant, or a problem with the city sewer, the water levels in your system can become unbalanced and dangerous to consume. 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. How else can this happen? Even minor fluctuations in the city water supply (such as another neighborhood using a large amount of water) can cause imbalances that can introduce contaminants into your water supply.

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 Clayton

A backflow preventer is installed in your irrigation system to prevent bacteria and other contaminants from entering your drinking and city water. Our Licensed Clayton Backflow Testers can perform a backflow test to see if there are problems with your Clayton 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 Clayton

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.
