Backflow Testing & Certification: Calworth Sprinkler Repair
Protecting Your Community’s Water Supply
At Calworth Sprinkler Repair, we take the safety of your drinking water seriously. A backflow prevention assembly is a mechanical device installed on your water line that prevents contaminated water from the irrigation system—containing fertilizers, pesticides, and animal waste—from flowing backward into the clean city water supply or your home's potable water.
Compliance with Texas Regulations
In Fort Worth, Haltom City, and surrounding North Texas municipalities, according to the Texas Commission on Environmental Quality (TCEQ), annual backflow testing is not just a safety recommendation—it’s the law. These regulations ensure that every connection to the public water system remains secure from potential cross-contamination.
The Detailed Backflow Testing Process
Our licensed technicians follow a rigorous, step-by-step protocol to certify that your assembly is functioning correctly:
Visual Inspection: We begin by checking the physical condition of the assembly for cracks, rust, or signs of tampering. We ensure the device is properly insulated and located above the flood level.
Water Shutdown: The water supply to the irrigation system is temporarily shut off at the shut-off valves. Note: This does not affect water inside your home.
Gauge Attachment: We attach high-precision differential pressure gauges to the test cocks on the assembly. These gauges allow us to measure the pressure differences between various chambers of the device.
Pressure Differential Check: The technician monitors the pressure drop across check valves. We are looking for a specific PSI reading (usually a minimum of 1.0 PSI or 2.0 PSI depending on the device type) to ensure the valve is seating tightly and holding pressure against backflow.
Air Inlet Opening Test: For Pressure Vacuum Breakers (PVB), we test to ensure the air inlet valve opens properly when internal pressure drops. This prevents a siphon effect from pulling water back into the system.
Second Check Valve Test: For Double Check Valve Assemblies (DCVA) or Reduced Pressure Zones (RPZ), we perform a secondary test to ensure both internal check valves provide redundant protection.
Record & Report: If the device passes, we record the serial number, location, and PSI readings. We then submit the required certification paperwork directly to the city or municipal water district on your behalf.
What Happens if the Device Fails?
If your backflow device fails the test, our team is equipped to perform immediate repairs. Common failures are caused by debris caught in the check valves, worn-out rubber seals, or freeze damage. Because we carry most common repair kits on our trucks, we can often clean, repair, and re-test the device in a single visit, saving you time and ensuring your system is compliant.
