Leccy, it's got to be on for at least 4 weeks, It's already gone mouldy, but the problem is I never go into the airing cupboard because the water is always on. The Larder is stacked full with carp, so I never noticed. I can't smell anything, so it had to gt to the state of the whole thing coming through the lounge wall, we must be taking 2 weeks already. Yesterday, I finaly heard the dripping and realised what was going on. My HA are good TBF. The electrician said to ask them for a gas one because they have to pay for the bottles, but I'm quite worried about my chest really. Thank you anyway. Tiddles wil kill me, no insurance.
