Re water tank rattling

2012paddy2012

For the last few mornings I have been hearing a strange vibrating rattle
Along the bathroom wall upstairs , I stuck my head up in the attic and the rattle seems to be coming from the water tank... Before I could get to the tank it stopped...the ballcock is fine it opens/ closes....the water level is about two inches from the overflow outlet...it looks ok.....

The heating was on co incidentally ... I wonder what is the cause of this...

no you need whats called an equilibrium ballcock ,that stops water hammer http://www.johnsonvalves.co.uk/float-valves/

€25 as opposed to less than €10 for a normal one ,well worth it to permanently stop water hammer
