Yes, high pressure jetting is generally safe for most pipe materials, including PVC, clay, cast iron, and concrete, provided it is performed by trained experts who adjust the water pressure accordingly. Professionals evaluate the condition of the drainage system before starting, ensuring the correct pressure setting and nozzle type are used. By tailoring these factors, high pressure jetting effectively clears blockages without damaging pipe walls. However, if a pipe is severely corroded or collapsed, alternative methods might be recommended to avoid complications. Experienced technicians often carry out CCTV inspections first to identify any structural weaknesses, cracks, or root intrusions. This preparation helps prevent further damage during jetting. When done correctly, it removes clogs and cleans the pipe interior, reducing future blockages. If you have concerns about your pipe material or system age, discuss them with a qualified drainage specialist. With the right approach, high pressure jetting remains a safe solution.
