Backflow Inspector Creve Coeur

Regular Backflow Inspections ensure that your water is safe to use both inside and outside of your home.

 Inspection Company St. Louis

To ensure that the drinking water inside your house doesn't mix with the water your sprinkler system uses to keep your lawn green, you install a backflow preventer. This is important because the water you have inside your house is used for entirely different purposes than the water you use for your lawn. It's important to inspect backflow preventers regularly to make sure that these waters don't mix. To have your backflow inspected, contact our backflow inspectors in Creve Coeur at (314) 450-0342.

Backflow Inspections Creve Coeur

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 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. 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. 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 Creve Coeur

A backflow preventer keeps your drinking water and your irrigation water separate. Our Licensed Creve Coeur Backflow Testers can check your Creve Coeur 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 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 Creve Coeur

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.
