Backflow Testing in Arlington Heights

Protecting Your Water Supply and Irrigation System

At Conserva Irrigation of Northwest Chicago, backflow testing is an important service for property owners who have irrigation systems connected to their water supply. Backflow occurs when water flows in the opposite direction than intended, which can allow contaminants such as fertilizer, dirt, or chemicals to enter clean water lines. This is why backflow testing is often required for irrigation systems connected to residential or light commercial properties.

Backflow preventers are mechanical devices installed on irrigation lines to help ensure that water flows in one direction only. These devices help protect drinking water from contamination that can occur when pressure changes in the plumbing system. Regular testing helps confirm that the device is working properly and continuing to protect the water supply.

Why Backflow Testing Is Important

Backflow can occur when there is a sudden drop in water pressure in the main supply line. When this happens, water from irrigation lines may be pulled backward into the clean water supply. Irrigation water may contain substances such as soil, lawn treatments, or standing water from sprinkler lines, which is why prevention is necessary.

A backflow preventer contains internal valves that close when pressure changes occur, preventing contaminated water from flowing backward. Over time, these internal components can wear out due to age, pressure changes, or outdoor conditions. Regular testing helps identify worn parts and confirms whether the device is functioning correctly.

Property owners are often required to complete annual backflow testing to comply with local regulations. Testing must be performed using approved equipment to measure pressure levels and confirm the device is operating correctly.

Don't let that testing notice sit on the counter. Check annual compliance off your list with a quick, professional backflow certification. Connect with our expert team online or call (847) 380-8536.

Our Backflow Testing Process

When scheduling a backflow test, the process typically begins with confirming the type of backflow device installed and its location on the property. Most devices are located outside near the foundation, side yard, or close to the irrigation system connection.

During a backflow testing visit, the technician performs several steps to evaluate the device and confirm it is functioning properly. The process usually includes the following:

• Locating the backflow preventer and visually inspecting it for leaks or visible damage.
• Connecting specialized testing equipment to the device.
• Measuring pressure levels and checking valve operation.
• Confirming the device prevents reverse water flow.
• Recording test results and noting any issues.
• Restoring the system to normal operation after testing.

Most residential backflow tests can be completed within a short visit, although the exact time depends on the device location and accessibility.

Backflow Devices and Irrigation Systems

Backflow preventers are commonly installed on irrigation systems because sprinkler lines are exposed to outdoor conditions. These lines often contain standing water, fertilizer residue, and soil contact, which increases the risk of contamination if backflow occurs.

Seasonal weather changes can also affect irrigation plumbing. Freezing temperatures, soil movement, and normal wear can affect seals and valves within the backflow device. This is one reason annual testing is recommended for many properties.

Backflow testing also provides an opportunity to identify other irrigation issues that may affect system performance. For example, pressure issues, leaks near the device, or shutoff valve problems can sometimes be identified during the testing visit.

Local Backflow Testing Considerations

Property owners with irrigation systems often schedule backflow testing during the irrigation season when systems are active and pressurized. This allows the device to be tested under normal operating conditions. Testing at the appropriate time helps ensure accurate results and reduces the risk of damage to irrigation components.

Local properties may have different types of backflow preventers depending on when the irrigation system was installed and local plumbing requirements at the time. Some systems use pressure vacuum breakers, while others use reduced pressure zone assemblies. Each device must be tested according to its specific requirements.

Understanding the type of device installed and keeping a record of past testing dates can help property owners stay organized and maintain compliance with local water safety requirements.

Frequently Asked Questions

1. How often do I need backflow testing?

Most irrigation systems require backflow testing once per year, although the exact requirement depends on local regulations and the type of backflow preventer installed.

2. Do I need to be home during the test?

In many cases, you do not need to be home as long as the technician has access to the backflow device and irrigation connection.

3. What happens if my backflow preventer fails?

If a device fails testing, repairs or replacement may be required to ensure the water supply remains protected.

4. Can backflow testing be done with other irrigation services?

Backflow testing can often be scheduled at the same time as irrigation system inspections, seasonal startup, or other sprinkler services.

5. How long does a backflow test take?

Most residential backflow tests take a short amount of time, depending on the device location and accessibility.

Maintaining Water Safety and System Performance

Backflow testing helps confirm that irrigation systems are operating safely and that backflow prevention devices are working correctly. Regular testing can help identify worn components, prevent contamination risks, and support proper irrigation system function.

At Conserva Irrigation of Northwest Chicago, backflow testing services are performed with attention to system safety, proper testing procedures, and clear documentation so property owners can maintain safe water systems and properly functioning irrigation equipment.
