Backflow Testing: A Step-by-Step Guide

Backflow occurs when water flows in the opposite direction of its intended course, which can happen in irrigation systems if there's a drop in water pressure. When backflow occurs, potentially contaminated water, chemicals, and fertilizers from lawns or gardens can flow back into the public drinking water supply. This creates a health hazard, as it could introduce harmful substances into the water that families rely on for drinking, cooking, and bathing.



A backflow prevention device is installed in irrigation systems to prevent this dangerous scenario. However, these devices are mechanical and can fail over time due to wear and tear, corrosion, or improper installation. Therefore, periodic inspections are essential.

Backflow testing ensures that the backflow prevention device is functioning correctly and is still capable of preventing contaminated water from re-entering the clean water supply. Most local municipalities, including those in Texas, require annual backflow testing by a licensed professional.

Here are a few key reasons why backflow testing is essential:

• Health and Safety: Backflow prevention devices stop hazardous materials like pesticides, fertilizers, and bacteria from entering the drinking water supply. Ensuring the device is working correctly is vital to avoid serious health risks.
• Legal Requirements: Many local governments, including Mansfield, TX, have strict codes and regulations that require regular backflow testing. Failing to comply can lead to fines or water shut-offs.
• Irrigation System Efficiency: A properly functioning backflow device helps maintain the efficiency of your irrigation system by ensuring clean water is always available for your plants and landscape.
  

At Anchor Irrigation, we perform backflow testing using a thorough and precise process to ensure your irrigation system remains safe and efficient. Here's what to expect when you schedule a backflow test with us:

Step 1: Locate the Backflow Prevention Device

Before the testing begins, the technician will locate your backflow prevention device. In most irrigation systems, the device is typically installed above ground near your water meter or along your main water line.

Step 2: Turn Off Water Supply

To prevent any disruption during the testing process, the technician will turn off the water supply to your irrigation system. This allows the device to be isolated so it can be thoroughly tested without interference from the water flow.

Step 3: Attach Testing Kit

The technician will attach a specialized backflow testing kit to the test cocks on the backflow prevention device. This kit measures water pressure and flow, allowing the technician to determine if the device is working correctly.



Step 4: Test Check Valves and Relief Valves

Backflow prevention devices have check valves and relief valves that need to be tested to ensure they open and close properly. The technician will test these valves individually by pressurizing the system and observing whether the valves open at the correct times. If any of the valves are not operating properly, they will need to be repaired or replaced.

Step 5: Restore Water and Provide Results

Once the testing is complete, the technician will restore the water supply to your irrigation system and provide a detailed report of the test results. If your system passes, the report will be sent to the local water authority to confirm compliance. If repairs or replacements are necessary, we will provide you with recommendations and a quote for the work.

The frequency of backflow testing largely depends on local regulations, but it is generally recommended (and often required) to have the test done annually. In Mansfield, TX, for instance, homeowners are typically required to schedule backflow testing once a year to comply with city ordinances.



Certain factors, such as an older irrigation system or frequent system repairs, may warrant more frequent testing. Additionally, if you notice issues like inconsistent water pressure, odd-tasting water, or visible water contamination, it’s crucial to schedule a backflow test as soon as possible.

While some irrigation maintenance tasks can be done by homeowners, backflow testing is a job best left to the professionals. Here are some of the reasons why hiring Anchor Irrigation for your backflow testing needs is a smart decision:
