Backflow Testing in Hilo

Certified backflow testing, annual reminders, and same-visit repairs for Hilo and the surrounding area — filed to County of Hawaiʻi standards.

On the windward side, Hilo's heavy rainfall keeps irrigation and drainage systems working hard, and the backflow assemblies on the potable side have to be spot-on. We serve Hilo homes, downtown businesses, and larger properties around the bayfront and the university, testing RP, DC, PVB, and SVB devices and filing compliant reports with the County. Whether you're managing a commercial kitchen downtown or a property near the water table, we keep your cross-connection paperwork current — and if a device fails, we can repair or replace it and re-test it right then, so you're not waiting on a separate crew.
