Backflow testing across Hawaiʻi Island

Kailua-Kona is home base for us, so most Kona appointments can be scheduled the same week. From Aliʻi Drive condos and vacation rentals to Kona's restaurants, coffee farms, and the commercial strips along Kuakini and the Queen Kaʻahumanu Highway, we test the irrigation, fire, and potable assemblies that keep West Hawaiʻi's water safe. We know how the Department of Water Supply runs cross-connection control in Kona and file every report the way the County expects. And because we're a licensed plumber as well as a certified tester, a failed device gets repaired and re-tested on the same visit — no second contractor, no weeks out of compliance.

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.

Waikoloa's resorts, vacation communities, and golf-course landscaping run extensive irrigation, which means a lot of backflow assemblies to keep compliant. We test single-family homes in Waikoloa Village as well as the larger multi-assembly properties along the resort corridor, coordinating with HOAs and property managers so nothing gets missed. Expect scheduling that works around guests, a consolidated report covering every device on the property, and in-house repairs the moment a device fails — one crew handles the test, the fix, and the re-test.

Up in Waimea (Kamuela), cooler upcountry weather and working ranch land shape how properties use water. We test backflow assemblies for paniolo-country homes, ag and equestrian properties, and Waimea's town businesses, verifying that irrigation and potable lines stay separated the way County rules require. Whether you're off Māmalahoa Highway or tucked into the pastures, we'll get you tested and documented on schedule — and because we're a licensed plumber too, a failed assembly is repaired and re-tested on the same trip instead of becoming a second appointment.

South Kona — Captain Cook, Kealakekua, and Hōnaunau — is coffee and farm country, where many properties lean on irrigation and catchment systems and cross-connection control matters most. We test residential and agricultural backflow assemblies throughout South Kona, making the drive so you don't have to, and file the compliant reports that keep your water and your neighbors' safe. Farm, home, or small business, we cover the South Kona coast — and when a device fails, we can repair or replace it and re-test it on the same visit.
