The water tank in the airing cupboard has a pin prick hole in it - I only discovered it last night - the water was spitting out and dripping down into the sitting room. I got some plumbing putty to try and seal the hole - but this isn't working. I have towels wrapped around the tank to try and absorb the water (which is working for the time being). Has anybody any advice on what to do - as I can't get a plumber until tuesday. Also does anybody know if this will be covered in my house insurance. Please help.
