Backflow Inspector Huntleigh

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

 Inspection Company St. Louis

Backflow preventers keep your drinking water and the water inside your house safe from the water you use outside. 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 Huntleigh at (314) 450-0342.

Backflow Inspections Huntleigh

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. Contaminants can enter an irrigation system from fertilizer or pesticides that are sprayed onto lawns. Minerals, bacteria, and different kinds of contaminants can collect in a stagnant system.

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. During this imbalance, the water in your irrigation system can back-up into your drinking water, which is dangerous. The next time someone runs the water, either for drinking or bathing, it could be contaminated. 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.

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 Huntleigh

A backflow preventer keeps your drinking water and your irrigation water separate. Our Licensed Huntleigh Backflow Testers can check your Huntleigh backflow tester to make sure that your water supply remains safe. 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 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 Huntleigh

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.
