combi boiler leaking!!

[skyblues11]

i know this is well off topic, but its kind of emergency!

pls help anyone! any advice would be welcomed.

after a long, hot shower just, i notice a line of water running down the wall downstairs.

i later discovered that water was dripping from a pipe that lead from the boiler. It only leaks when i use hot water. so far the heating had not been affected. It could be further up in the heater and the water had travelled.

the pressure seems to be at the 1.5.- 2 position ( without using any hot water).

i have to admit , i never had it serviced since moving in in feb 2006.

its a direct feed system - i have no hot water tank. just turn on the tap and the hot water comes.

thanks
