Backflow Prevention & Testing

Serving McHenry, Crystal Lake, Lake in the Hills and Surrounding Areas

A backflow prevention system is a critical part of your plumbing, and backflow testing services are essential to keeping your system working.

If you have a business with a fire control system or if you’re a homeowner with an irrigation system, then you have a backflow prevention system. This system helps prevent contaminated water from your property from flowing back into the water system. Protect your home or business with regular system tests to ensure it is functioning properly.

Black Diamond offers backflow prevention testing to ensure your system is working as it should. This is a required test that you need to have performed every year or every time you install or reactivate a backflow prevention system. If you have a system that needs testing, trust Black Diamond to perform the testing you need.

If your system has an RPZ device that needs to be tested, schedule testing with Black Diamond. You can call us at 815-444-0979 or contact us online for help. We serve the entire Chicagoland area, including Crystal Lake and McHenry.

About Backflow Prevention System Testing and Inspections

The only way to protect against chemical or biological contamination of your water supply, particularly with fire-retardant systems or irrigation systems, is with a backflow prevention device. Presently, the National Fire Protection Association requires regular testing and inspections. You can trust our trained and licensed plumbing specialists to test and inspect your plumbing system properly.

At your annual inspection and testing appointment, we will:

  • Assess the backflow prevention valves for proper operation
  • Check the metal, plastic, and rubber components for signs of wear or aging
  • Perform a test run on all backflow prevention devices to ensure they’re operating properly
  • Check for any code violations and to ensure the system is adequate for your property’s water supply

Backflow prevention and inspections in Chicago are required by law. Call Black Diamond at 815-444-0979 now or contact us online to schedule yours.

Frequently Asked Questions

Here are some common questions and answers about backflow prevention devices.

What is backflow?

Municipal water lines send potable (clean) water under high pressure into your home or business. Occasionally dirty water can push back through the clean water lines. This water can have everything from feces to pesticides in it, and this creates a serious risk. Backflow can happen in places where potable and non-potable water cross. So it is also a higher risk in properties with irrigation or fire prevention systems.

What are backflow prevention services?

Backflow prevention services test, inspect, and maintain backflow prevention devices. Therefore these devices are required in many commercial properties and some residential properties in Chicago and the surrounding communities.

Why are backflow prevention tests required?

Backflow prevention testing and inspection are required because of the importance of these devices. The valves are under an incredible amount of pressure inside these devices, and over time they can weaken and fail. If they fail, your building’s water supply is potentially exposed to harmful chemicals.

What happens if backflow occurs?

If your backflow prevention device fails, your building’s freshwater supply can become contaminated. This can make the people that use that water sick.

How long do backflow valves last?

Backflow prevention valves are built to last. These have a typical life span of 50 years or longer. However, they can eventually break down, and the amount of pressure placed on one will have a direct impact on how long it lasts.

If you are overdue for backflow prevention testing, or if you suspect a problem with your backflow valves, don’t wait. Your safety is at risk. In Chicago, Crystal Lake, and McHenry, contact Black Diamond or call 815-444-0979 to schedule service.
