Backflow Prevention for Irrigation Systems in St. Charles, MO

Irrigation systems in St. Charles, MO are a common source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply. Installing a dedicated backflow preventer for your sprinkler system is often a local code requirement. We are experienced in selecting and installing the correct device, such as a pressure vacuum breaker or atmospheric vacuum breaker, to protect your home's main water line from contaminants coming from your landscape irrigation.

Pool and Spa Fill Backflow Protection in St. Charles, MO

An auto-fill line or hose connection on a pool or spa creates a direct path for chlorinated water to reach the supply. We install the correct device on pool fill lines and check that hose bibbs have vacuum breakers. This simple step protects your household water and keeps you in line with local code. We can add the work when a pool is being built or renovated.

Backflow Testing and Certification in St. Charles

Most water providers require testable backflow assemblies to be certified at installation and then once a year. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it right away with genuine parts. We submit passing results so you avoid compliance letters or service interruption.

Double Check Valve Assembly Installation in St. Charles

Double check assemblies are used for low hazard connections such as many fire sprinkler systems and some irrigation lines. They have two spring-loaded check valves and test cocks for annual certification. Unlike an RPZ, they do not discharge water, so they can be installed in vaults or below grade where local rules allow. We size them to avoid too much pressure loss on your system.

Reduced Pressure Zone Assembly Installation in St. Charles, MO

RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes.

Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested easily. We carry proven brands like Watts, Febco, Wilkins and Apollo.
