Annual Backflow Preventer Testing in St. Charles & West County

Keep Your Home’s Water Supply Healthy and Safe

Caring for a lawn or landscape takes more than just a healthy dose of water.

There are many toxic chemicals like fertilizers and pesticides, as well as manure and other contaminants that can become a real health hazard if they should get into the water supply. That’s why it’s important to stop these and other pollutants from getting into your drinking water. To make sure that never happens, we provide our customers with a sprinkler system backflow preventer test. To learn more, call (636) 692-4441.

Why It’s Important to Have a Sprinkler System Backflow Preventer

The backflow is usually located next to the foundation on the same side of your home as your water service.

The backflow preventer serves as a preventative measure against contaminating the potable water supply and a place where if a leak were to occur, the system could be isolated.

Know the Facts About Backflow Preventers

With a sprinkler system backflow preventer you get solid peace-of-mind as well as:

  • An all brass backflow preventer construction
  • All copper piping to and from backflow above grade
  • Optional unions for easy off-season removal
  • ASSE and Foundation for Cross-Connection Control at USC certified

Why Backflow Preventer Testing?

There are a few reasons why it is important to have a backflow preventer, while providing irrigation for the lawn and landscape around the home.

  • Reduces the risk of contaminated water leaking into the water supply
  • Ensures water is suitable for drinking and other common uses
  • Keeps the water pressure even to prevent backpressure in the irrigation system

Let the pros at Pro Outdoor come out and inspect your irrigation system for breaks or leaks, and ensure that you have a safe and secure water supply for your sprinkler system.

Backflow Conditions

In the event of a water main break or a major power outage, a backflow condition can occur. This will cause the water from your irrigation system to be pulled into the potable side of your water supply creating contamination. A backflow preventer is the key device in keeping your family and community safe and the water supply pure.

Backflow Preventer Testing

It’s important to have your sprinkler system’s backflow preventer device annually inspected to make sure it provides solid protection against the health hazards of a contaminated water supply. Pro Outdoor’ backflow test service includes:

  • All paperwork and tagging
  • Test information filed with appropriate county or water purveyor
  • Testing the backflow prevention device
  • If repairs are necessary, an estimate will be provided prior to repairing device

Frequently Asked Questions (FAQ)

Why is backflow preventer testing mandatory in the St. Louis area?

If your device fails the backflow preventer testing, it means it is not protecting your water supply. We will provide an immediate estimate for the necessary irrigation system repairs or replacement. Once repaired, we will re-test the device to ensure it passes before submitting the final paperwork.
