Hi aauk25.

Re your question.... well erm.......?

anything "Whistling-Sound" related is most likely a plumbing related problem...
as electricity generally does not make whistling sounds in either normal or fault conditions?.

And as this is basically an "electrical forum", you may not get much help from here??

Electrical faults are typically more: visible arcing and sparking flashes, crackling noises, burning/melting smells, power tripped off, etc....

I am guessing it could be "trapped air related"..?
But I may be totally wrong?
