Backflow Repair

A properly functioning backflow prevention assembly is critical to protecting the public water supply from contamination. In Post Falls, ID, these devices are required by law for irrigation systems, commercial properties, and certain residential setups. If your backflow device fails annual testing or shows signs of wear, prompt repair or replacement is essential to maintain compliance. At Sego Backflow and Sprinkler LLC, we specialize in certified backflow repair and installation, ensuring your system meets all local and state standards.

Backflow assemblies are mechanical devices, and over time, components inside them can wear out or become obstructed. Common failure points include internal springs, check valves, or seals that no longer maintain the required pressure differential. These failures are typically identified during required annual testing or when issues such as leaks or irregular water flow are observed.

When a device fails inspection, it is considered non-compliant and must be repaired or replaced promptly. Our certified technicians are trained to identify the specific point of failure and determine whether the device can be serviced or needs a full replacement.

We begin each repair or installation with a detailed inspection of the device. This includes pressure testing and disassembly when needed to verify which components are malfunctioning or damaged.

If a device cannot be repaired—due to internal corrosion, extensive mechanical failure, or a model being outdated—we offer full backflow replacement services. This includes safe removal of the old assembly, proper installation of a new, approved model, and complete testing and certification of the new unit.

All installations are performed to meet plumbing code requirements. We follow Idaho state regulations and Post Falls city ordinances to ensure each device is installed at the correct height, orientation, and with the required clearance and drainage.

Backflow devices must also be installed in a way that allows for annual testing and maintenance. Our technicians place each assembly in an accessible location and provide any necessary insulation or housing to protect it from weather-related damage.

For new irrigation systems or recently constructed buildings, we also offer complete backflow installation as part of the system build. We help determine the correct device for your application—whether it’s a double-check assembly or reduced pressure zone (RPZ) model—and ensure proper setup from the start.

Repair and installation of a backflow prevention device is only part of the process. Once the work is complete, the device must be tested and certified by a licensed professional. Our team handles this requirement immediately after each service.

We conduct a certified performance test and generate the official report required by your water provider. This documentation includes device specifications, pressure readings, and confirmation of compliance. We then submit the report directly to the appropriate agency on your behalf, keeping you clear of any regulatory penalties or service disruptions.

This streamlined process makes it easy for homeowners, property managers, and business owners to maintain full compliance without managing complex paperwork or deadlines.
