Backflow Inspections

Caruth’s in-house backflow inspection team consists of experienced professionals who specialize in the inspection of both fire and domestic backflows. They possess the necessary skills and knowledge to effectively inspect backflows according to industry standards and local regulations. Their expertise ensures the proper functionality and reliability of backflows, contributing to enhanced fire safety in buildings.


The purpose of a backflow preventer is to protect the potable water supply from contamination or pollution. It prevents water from flowing back into the municipal water system, ensuring that the water used for fire sprinkler systems and domestic lines remains separate and does not compromise the water supply’s quality and safety.


The different types of fire sprinkler backflows include double check valve assemblies (DCVAs), reduced pressure zone assemblies (RPZs), and pressure vacuum breakers (PVBs). Each type of backflow preventer provides varying levels of protection against water contamination, depending on the specific application and local regulatory requirements. Caruth’s inspectors can inspect most types of backflow systems.
