If you have ever dealt with a slow sink, a gurgling floor drain, or a blockage that keeps coming back, a plumber may have suggested jetting. So, what is drain jetting? It is a drain cleaning method that sends a high-pressure stream of water through a flexible hose and a specialised nozzle to scrub the inside of a pipe and flush the debris away. Unlike a plunger or a chemical cleaner, it cleans the whole pipe wall, not only the clog you can see.

In this guide, we explain how drain jetting works step by step, what equipment is used, which problems it solves, how it compares with other methods, whether you can do it yourself, and what affects the cost. If you already suspect a problem and want to know the warning signs, read our separate guide on when you need professional drain jetting services.

Quick answer: Drain jetting, also called hydro jetting or water jetting, cleans blocked or slow drains by pushing high-pressure water through a hose and nozzle. The water breaks up grease, sludge, scale, and debris, then flushes it down the line. It is used on kitchen, bathroom, and floor drains as well as main sewer lines.

Drain jetting is a professional drain cleaning technique that relies on water pressure instead of chemicals or cables. A jetting machine pumps water at high pressure into a reinforced hose. At the end of the hose sits a nozzle with several small openings that direct the water in different directions. When the hose travels through the pipe, those jets cut through build-up and wash it toward an exit point.

You will also hear the terms hydro jetting and high-pressure water jetting. In everyday use, they describe the same idea: cleaning pipes with pressurised water. Some contractors use hydro jetting for heavier, higher-pressure work, but the principle does not change.

The key advantage is thorough cleaning. A cable or snake can punch a hole through a clog and restore flow for a while, but a layer of grease or sludge often stays on the pipe walls. Jetting scours that layer away, which is why it is popular for recurring blockages and for kitchens that produce a lot of grease. A trained technician can handle this safely, and our drain cleaner in Dubai service offers it for homes and businesses.
