Drain descaling is the process of removing hardened mineral deposits, limescale, or other encrusted material that accumulates on the interior walls of pipes over time. In areas with hard water, minerals such as calcium and magnesium can build up, gradually narrowing the diameter of the pipe and restricting water flow. This not only leads to slower drainage but can also create an ideal environment for further blockages to form, as grease and debris become trapped in rough, uneven surfaces. Descaling helps restore pipes to a smoother condition, improving water flow and reducing the likelihood of recurring clogs. It also extends the life of your drainage system by preventing corrosion hotspots that can develop under layers of scale. Typically carried out using high-pressure jetting with specialised nozzles or mechanical cutting heads, drain descaling is an important maintenance procedure that can save you from more significant repairs or replacements in the future.
