Backflow Inspector Brentwood

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

 Inspection Company St. Louis

Backflow Preventers play the important role of separating your drinking, cooking, and bathing water from the water you use to take care of your lawn. Keeping these two waters from mixing is important because the water used inside your home is held to a different standard of quality than the water you may 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 Brentwood at (314) 450-0342.

Backflow Inspections Brentwood

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?

When an irrigation system is installed, it must also be paired with a backflow valve. 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. This can cause water from the system to back-up into the drinking water supply. 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 Brentwood

A backflow preventer is installed in your irrigation system to prevent bacteria and other contaminants from entering your drinking and city water. Our Licensed Brentwood Backflow Testers can perform a backflow test to see if there are problems with your Brentwood irrigation systems backflow device. This test includes shutting off water supply to allow for investigation of the plumbing system and observing the valve to see if the water is running backwards (which is good), or if the relief valve opens, which is an indication that it needs to be replaced. 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 Brentwood

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.
