Drains & sewer services in Honolulu
Drain cleaning
UrgentIf one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.
Hydro jetting
Hydro jetting cleans the full width of a drain pipe with high-pressure water, washing out grease, scale and fine roots that a cable only punches a hole through. It works best on sound pipe and is usually done after a camera inspection confirms the pipe can take it.
Sewer camera inspection
A sewer camera inspection runs a waterproof camera through the line from your house to the city main and records what it finds: roots, cracks, sags, offset joints or collapsed pipe. It's the best way to decide between cleaning, spot repair and replacement.
Sewer line repair
UrgentA damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.
Local conditions
Drains & sewer in Honolulu: what's different
Windward downpours test drains across Honolulu, and homes on steep valley slopes like Manoa have long sewer laterals with drainage challenges.
Older homes have cast-iron and clay drains that corrode and crack in the humid climate.
The city handles wastewater, and the lateral from the house to the main belongs to the owner. A camera inspection shows whether a recurring clog needs repair.
Older high-rises have shared stacks where a clog affects several units, and building management handles those repairs.
