High-pressure water jetting, or hydro-jetting as it’s sometimes called, is a way to blast away grime, grease, tree roots or other debris that has built up in your kitchen, bathroom or sewer drains.
Water is forced through a hose and nozzle at high speed, which dislodges debris and sends it down the drain. The pressure is enough to break through the blockage and split it into smaller pieces that wash away.
This process is repeated until the drain is clear. The water pressure is adjusted to ensure that it is powerful enough to remove the blockage but not so powerful that it damages the drain.
It’s a very versatile technique that can remove all kinds of blockages including grime, grease, and hair.
