As it strives to help local residents keep the area around their homes green and bright, Oahu Sprinkler provides an array of vital irrigation services, including installation and repair coupled with stellar customer service.

Oahu Sprinkler offers peace of mind with immediate responses to service and repair projects, as well as free estimates for installation of new irrigation systems. The company previously operated as Diamond Head Sprinkler dating back to 1974, but in 2014, owner Ryan Thornton took over the operation and expanded the business to adequately serve customers across Oahu, from Hawaii Kai to Pupukea.

“Our repair service is crucial to maintaining your sprinkler system — if you start to see spikes in your water bill, call us to help diagnose the problem and address it immediately,” Thornton said.


Thornton explained that issues can arise over time with irrigation systems that may have been installed with flaws, including valves that star t to leak when subjected to excessive water pressure throughout the array of underground pipes. As valves leak, the influx of water attracts tree and grass roots, which can lead to additional breakage throughout the system. The professional team at Oahu Sprinkler can address the problem and fix the system so it functions efficiently for years to come, thus saving valuable time and money for the property owner.

During the current rainy season in Hawaii, the Oahu Sprinkler team can also address drainage issues, including the mitigation of standing or ponding water during and after heavy downpours. Thornton recommended adding French drains, which filter water from the surface through an underground pipe that diverts the runoff away from building foundations or retaining walls. These investments not only protect landscapes from being inundated with water, but also help fend off costly structural repairs in the future.

Oahu Sprinkler can even help with fixing and optimizing landscape lighting, whether the lights are intended to spotlight trees or other focal points within a landscape arrangement, or illuminate walking paths.
