What Is Hydro Jetting?

Hydro jetting uses high-pressure water — typically 4,000–5,000 PSI — to blast through blockages and scour pipe walls clean. It's significantly more thorough than a standard electric eel (drain snake).

When Is Hydro Jetting Required?

  • Heavy grease and fat build-up that an eel can punch through but not remove
  • Root intrusions requiring cutting and flushing
  • Scale deposits in older pipes
  • Commercial kitchens with regular grease blockages
  • Drains that block repeatedly within weeks of being cleared

How It Works

A nozzle is fed into the drain and water is pumped at high pressure. Forward-facing jets break up blockages while rear-facing jets propel the nozzle forward and flush debris back toward the cleanout. The result is a pipe that's substantially cleaner than what an eel achieves.

Is It Safe for All Pipes?

Hydro jetting is safe for most drain types including PVC, clay and cast iron — provided the pipes are structurally sound. It's not appropriate for pipes that are cracked or partially collapsed, as the pressure can worsen damage. A CCTV inspection first rules out structural problems.

Sydney Pricing

Hydro jetting costs more than a standard drain clearance — typically $350–$700 for a residential job. Given the thoroughness of the result and the extended time before re-blockage, it's often better value over 12 months.
