Residential Backflow Testing
Certified annual testing for home irrigation, pool, and fire assemblies — booked in minutes, filed for you.
If your home has an irrigation system, a pool auto-fill, a fire line, or a catchment connection, the County of Hawaiʻi almost certainly requires that backflow assembly to be tested every year. Miss it and you can end up with a compliance notice — and, left unresolved, a shutoff.
We connect a freshly calibrated gauge to your RP, DC, PVB, or SVB assembly and verify that every check valve, relief valve, and shutoff performs to spec. You get a clear pass/fail report formatted to County of Hawaiʻi Department of Water Supply requirements, filed on your behalf — and a friendly reminder before it's due again next year.
And if something fails, don't worry — it happens often, especially with older devices. We'll show you exactly what failed, walk you through your next steps, and come back to re-test once it's sorted. No mystery fees — just clean water and clear paperwork.
