Services
Trenchless Pipe Repair
Trenchless pipe repair restores damaged plumbing without excavation. Using NuFlow technology, we insert a durable epoxy liner into existing pipes, sealing leaks and preventing root intrusion. This method preserves landscapes and reduces costs compared to traditional repiping, offering a long-lasting solution for residential and commercial properties.
Backflow Testing
Backflow testing ensures water supply safety by inspecting prevention devices for proper function. Our licensed technicians install and test pressure vacuum breakers and reduced pressure zone devices, complying with Hawaii regulations. Regular testing prevents contaminated water from entering clean systems, safeguarding homes and businesses.
Drain Cleaning
Drain cleaning services address blockages using hydro jetting and snaking techniques. High-pressure water jets clear stubborn clogs, while augers remove debris from pipes. We service residential and commercial drains, restoring proper flow and preventing backups in kitchens, bathrooms, and sewer lines.
Water Heater Service
Water heater service includes installation, repair, and maintenance of tank and tankless systems. Our technicians diagnose issues like leaks, inconsistent temperatures, and pilot light failures. We specialize in energy-efficient solar water heaters, ensuring reliable hot water supply for residential and commercial clients.
Camera Inspection
Camera inspection uses advanced tools to diagnose pipe issues without excavation. A waterproof camera navigates sewer and drain lines, identifying cracks, root intrusion, and blockages. This non-invasive method allows precise repairs, reducing costs and time for trenchless solutions like relining or spot fixes.
