24/7 emergency service across Oʻahu Call (808) 630-9966

Call now — then stop using water

(808) 630-9966. We answer 24 hours a day, weekends and holidays included, and most emergency calls we reach within one to two hours.

While you wait, the single most useful thing you can do is put nothing else into the system. A backed-up cesspool, septic tank or main line has nowhere left to send it, so every flush, tap and wash cycle pushes more of it back toward the house.

  • Stop flushing toilets, and stop running taps, showers, the washing machine and the dishwasher
  • Keep people and pets away from anything that has surfaced, indoors or out — raw sewage is a health hazard, not just a mess
  • Do not pour drain cleaner in. It will not touch a full tank or a blocked main, and it makes the system dangerous for whoever opens it
  • If it is safe, note whether it is one fixture or several — it is the first thing we will ask
  • Leave the lid alone. Cesspool and septic covers are heavy, and the gas underneath can be lethal in an enclosed space

Is this an emergency, or can it wait until morning?

Not everything needs a call-out at 11pm, and we would rather tell you that than bill you for it. Here is the honest split.

  • Call now — sewage backing up inside the building
  • Call now — more than one fixture backing up at the same time, which means the main line rather than a local clog
  • Call now — waste surfacing in the yard, or ground over the tank that is suddenly wet
  • Call now — a cesspool or tank overflowing at the lid
  • Usually can wait — one slow drain, on its own
  • Usually can wait — a single gurgling toilet with everything else draining normally
  • Usually can wait — a faint smell outside, with no standing water

If it can wait, it will also cost you less — a scheduled visit is a normal job. If you are not sure which side of the line you are on, call and describe it. We will tell you straight.

What the symptom usually means

The same thing looks different depending on where it shows up first.

  • Every drain in the house slowed at once — the main line or the tank, not the fixtures. Nothing you do at a single sink will help
  • Toilet backing up when the washing machine drains — classic full-tank or blocked-main behavior; the system is sending water back the easiest way out
  • Sewage in the lowest fixture — a ground-floor shower or floor drain goes first because it sits lowest in the run
  • Soft or wet ground over the tank or drain field — it is surfacing because it can no longer soak away
  • Smell but nothing visible — often a failed seal or a dry trap rather than a backup, and usually not urgent

Whatever it turns out to be, we camera the line before quoting anything that involves digging. See drain cleaning, cesspool pumping and septic pumping for what each job involves.

What happens when you call

No queue, no ticket, no callback window.

  • You describe what is happening and where — one fixture or several, inside or outside
  • We tell you whether it needs someone tonight or whether it will keep until morning
  • If it needs someone now, we tell you what we can about cost before we set off — and the firm number once we have seen it
  • We dispatch across Oʻahu — windward, leeward, North Shore and town. Most calls we reach within one to two hours, traffic depending
  • We pump, clear or camera as the situation needs, and tell you what caused it before we leave
