This has been an ongoing problem for us for a while now.
Sometimes while away, when we make coffee, it smells like the water is burnt.
The water comes from home. It's been stored in a flexible poly type bladder, a hard black poly tank, and the clear poly type water containers.
We've used an aluminium and stainless billy.
Times we've boiled the water for up to a minute so it's bloody hot and other times turned off the heat just as bubbles start forming on the bottom of the billy.
We're having trouble trying to work out why the water ends up smelling burnt.
If you drink the water cold it smells OK.
Any ideas?????????
