Just done a quick test. If the upstairs tap is turned on for 20
seconds, ten seconds later the boiler (downstairs) makes a huge
vibrating noise and all flames go out (including the pilot).

Help!

Get someone in to look at for you Tc. It could be a multitude of things
that will take forever to explain and test if you have to keep coming back
and forth to the group for more info' on it. Get a man in, is your quickest
and safest method on this one mate. :-( sorry :-(
