• 1. Leaking radiator
    If the body of the radiator is leaking, this is generally a symptom of internal corrosion and unfortunately means that it will have to be replaced. At the same time the system will need to be flushed out to remove the particles that caused leak.
  • 2. Leaking pipe joint
    If the leak is at the radiator valve joint, gently tightening it may be all that is necessary.

    If it is the valve that is leaking, or a soldered pipe joint then this would require an engineer visit.
  • 3. Leaking pipes
    • If the leak is at a joint, tightening a little with a spanner might solve the problem.
    • If the leak is at a soldered joint, it will need to be treated by an engineers visit.
    • If the pipe is leaking, the pipe will need be replaced by an engineer.
