The frequency of drain descaling depends on factors such as water hardness, usage patterns, and the overall condition of your drainage system. In areas with very hard water, pipes may scale up more quickly, requiring descaling every few years. Commercial kitchens or facilities that handle large volumes of hot water and grease may benefit from more frequent maintenance—perhaps annually or bi-annually—to prevent disruptive blockages. Conversely, properties in regions with softer water might go longer between treatments without experiencing significant build-ups. A CCTV inspection can help determine the appropriate interval by revealing how much scale is present and how quickly it accumulates over time. Additionally, noticing a drop in water flow or an increase in minor clogs may indicate the need for descaling sooner rather than later. Regular preventative maintenance ensures that pipes remain clear and extends the lifespan of your entire drainage network, ultimately saving on larger repair costs.
