Hydro jetting is recommended when a drain or sewer line has buildup on the pipe walls — grease coating, mineral scale, or a root mass — that a cable auger cannot fully remove. Where a snake punches a hole through a blockage and restores flow, hydro jetting scours the pipe walls clean from the inside out, eliminating the buildup that causes the problem to recur. If you have had a drain snaked multiple times and the slow drain or backup keeps coming back, hydro jetting is almost certainly the right next step. Done uses camera inspection to confirm pipe condition before jetting, because the method requires a pipe that is structurally intact — a camera look first ensures the water pressure goes toward cleaning the line, not worsening a crack.

How Hydro Jetting Works

A hydro jetting machine connects to a specialized nozzle on a flexible hose that is fed into the pipe through a cleanout. The nozzle directs high-pressure water — typically 1,500 to 4,000 PSI for residential lines — in multiple directions simultaneously: forward jets cut through and loosen blockages while rearward jets propel the nozzle through the pipe and flush dislodged material downstream toward the main. The pressure and nozzle type are selected based on pipe diameter, material, and what the camera showed. The result is a pipe interior that is genuinely clean — not just unblocked — which is what prevents the problem from returning as quickly as it otherwise would.

When Hydro Jetting Is the Right Call

  • Recurring slow drains or backups: If cable cleaning has been done before and the problem came back within months, buildup on the pipe walls is the likely cause — jetting addresses the root cause rather than just the symptom.
  • Grease-heavy kitchen lines: Restaurant and home kitchen drains accumulate grease that solidifies on pipe walls and catches everything that follows. Snaking moves through it; jetting removes it.
  • Main sewer line maintenance: As a proactive maintenance measure, jetting cleans the full lateral of mineral scale, light root growth, and debris buildup — significantly extending the interval before the next cleaning is needed.
  • Root intrusion (moderate): Hydro jetting cuts through root masses effectively and flushes the debris out. For heavy root intrusion, cable cutting may be done first to break the mass up before jetting finishes the job.
  • Pre-lining preparation: Before a trenchless pipe liner is installed, the line must be thoroughly cleaned so the resin bonds properly to the pipe wall. Hydro jetting is the standard preparation step.
  • Hard water scale: Denver’s notoriously hard water deposits calcium and magnesium scale on pipe interiors over time. Jetting removes this mineral buildup in a way that snaking cannot.

When Cable Snaking Is Sufficient

Not every drain problem needs hydro jetting. A hair clog near a bathroom drain opening, a soft food debris blockage in a kitchen sink P-trap, or a fresh blockage in a line that otherwise shows clean walls on camera — these respond well to cable snaking without the added cost and setup of jetting. Done matches the method to what the camera shows; if the line walls are clean and the blockage is isolated, snaking is the appropriate and efficient choice. The goal is the right tool for the situation, not the most powerful tool available.

Does Hydro Jetting Damage Pipes?

When performed on a pipe that is in adequate structural condition, hydro jetting does not damage the pipe. The camera inspection before jetting is what makes this determination — if cracks, significant corrosion, or structural weakness are visible, jetting pressure is adjusted or an alternative approach is chosen. Older clay tile and cast iron lines that are in good shape handle jetting fine; heavily deteriorated or cracked pipes would need repair before jetting is appropriate. This is precisely why Done does not jet without a camera inspection first.

If you have a recurring drain or sewer problem, or you want to proactively clean your main line before issues develop, hydro jetting may be the solution. Done also offers drain cleaning for single-fixture clogs and full sewer services when the main line is involved.
