posted this a little while ago and its disappeared. Can anyone help with water tank caps. I get the function. When removed they spin when locked and are solid when unlocked. I fit them in the unlocked position by pushing them in and turning until they click, then I lock them and they spin clockwise ok but are hit and miss when spinning anticlockwise as sometimes they will remove the cap. I have tried packing the rubber washer by cutting out a thin bit of plastic and putting it under the rubber seal but didnt help. They appear to work most times when Ive removed the rubber seal altogether. And solution would be greatly appreciate. Cheers
