Boiler is leaking
Possibly an indication of a serious fault, if you don’t fix a leaking boiler quickly the internal parts of your boiler could corrode, making it harder to repair in the future.
What is causing the leak?
Due to a variety of causes, a leaking boiler could be symptomatic of a crack in one of the boiler’s cast iron (or aluminium) sections or a broken seal on the boiler’s circulation pump.
How can I fix the leak?
While you may be able to isolate the source of the leak to help diagnose the problem, you should always contact your local heating engineer when dealing with a faulty boiler.
