Alpha Omega Plumbing Inc is a plumbing company based on Koapaka Street in Honolulu, specializing in drains, sewers, and septic systems across Oahu. Its listed services include drain cleaning and clogged drain repair, hydro jetting, sewer repair, septic and cesspool pumping, cesspool-to-septic conversions, water heater service, leak detection, and sump and well pump service, with 24/7 emergency availability. The company operates with an explicit focus on sewer and septic rather than general repair alone. The company's service model centers on compliance and prevention: its site describes cesspool inspection, pumping, and conversion work tied to Hawaii's state cesspool upgrade requirements, with walkthrough explanations of tank condition during pump-outs. Review snippets describe clear upfront pricing, honest assessments of older-home plumbing, and weekend responses for drain backups cleared within hours. The island-wide coverage spans Honolulu, Pearl City, Aiea, Waipahu, Kapolei, Ewa Beach, Mililani, Kailua, Kaneohe, and Hawaii Kai. This is a fit for Oahu homeowners dealing with septic or cesspool obligations — a pressing concern under the state's cesspool upgrade law — as well as anyone facing drain backups, sewer repairs, or water heater failures. The 24/7 emergency line makes it relevant for burst pipes and sewage backups that cannot wait. For property owners comparing septic specialists, the combination of pumping, inspection, and conversion guidance offers a single point of contact for the full lifecycle of a cesspool system.
