Hydro Jetting

Hydro jetting uses a specialized machine that pressurizes water and forces it through a nozzle-equipped hose into the pipe. The nozzle design controls the spray pattern—some shoot backward to propel the hose forward, others spray in a 360-degree pattern to scour walls. It's far more aggressive than a plumbing snake and will cut through grease buildup, soap scum, mineral deposits, and soft tree roots that a cable can't reach or fully clear.

In the field, hydro jetting comes after you've diagnosed a stubborn clog or slowdown that snaking didn't fix, or when a line has recurring blockages from grease or buildup. You run a camera first to confirm the line is solid—don't hydro jet a pipe with cracks or weak spots or you'll blow it apart. The pressure and volume also let you flush debris downstream instead of pulling it back out.

Watch for soft PVC, old cast iron, or clay pipes; those can fail under full pressure. Always verify the main line to the city or septic can handle the surge of water and solids you're about to send its way. It's a heavy-duty tool that works when nothing else will, but you need good information about pipe condition before you pull the trigger.
