When performed by trained professionals, drain descaling is generally safe for a wide range of pipe materials, including PVC, clay, cast iron, and concrete. Technicians assess the condition of the pipes before choosing the appropriate method and tools. For instance, older or more delicate pipes may require lower-pressure jetting or gentler mechanical attachments to prevent damage. Modern drainage systems, designed to withstand higher pressures, can often tolerate more aggressive cleaning techniques. The key is adjusting the pressure and the type of cutting or jetting head to match the pipe’s durability and the extent of the scale. Additionally, CCTV inspections provide crucial information about any existing fractures or weaknesses that could be exacerbated by descaling. By proceeding with caution and expertise, professionals can successfully remove encrusted deposits without compromising the structural integrity of your drains. In most cases, descaling is an essential and safe procedure to enhance drainage performance.
