Water should only flow one way
Out to your taps, sprinklers, and hoses — never backward into the drinking supply you share with your neighbors.
But pressure doesn't always behave
A main break, a fire hydrant opening, or a pump failure can reverse the flow — pulling fertilizer, soap, or boiler water toward the potable line.
A backflow assembly stands guard
RP, DC, PVB, and SVB devices are one-way gatekeepers. Check valves hold, the relief valve vents, and contaminants never make it back.
We test it and prove it works
A calibrated gauge verifies every part, and you get a County-compliant pass/fail report — plus a reminder before it's due again.
Clean water. Clear paperwork. Zero stress.
Backflow testing, done right
From a single home irrigation device to a whole HOA's worth of assemblies — certified testing, clear reports, and compliance you don't have to think about.
One morning a year. We handle the rest.
Follow along on a typical Big Island test day — about an hour, start to filed report.

The truck rolls out of Kona
You picked your slot online after last month's reminder — no phone tag, no “sometime between 8 and 2.” Just a confirmed time on your calendar and slippers on the porch.

The gauge goes on
A calibrated test kit hooks up to your assembly — RP, DC, PVB, or SVB. For most tests the water stays on, so your morning coffee doesn't even notice.
Holding steady. Calibrated gauge, honest reading — the needle doesn't lie. - 07:50
Every check, verified
Check valve one: holds. Check valve two: holds. Relief valve: opens right where it should. If something's off, you get straight talk and a fair path to fix it — not a mystery invoice.
- Check valve #1 — holds tight
- Check valve #2 — holds tight
- Relief valve — opens on spec
