What Is Descaling and When It’s Needed After Hydro

Hydro jetting is designed to blast away grease, sludge, and other debris deep inside a drain line using high-pressure water. While it’s highly effective at clearing many obstructions, it doesn’t always solve every type of buildup—especially when mineral scale or hard deposits have formed on the pipe walls.

That’s where descaling comes in. In simple terms, descaling is the removal of mineral deposits (often calcium, magnesium, or similar compounds) that can adhere to plumbing surfaces over time. These deposits can narrow the pipe, trap other debris, and contribute to recurring clogs even after a thorough jet.
