Hi there, I was just googling taplocks there and this appeared right near the top. I realise this form is three years ago bit I was wondering if you ever got to the bottom of this problem? I have an autistic brother and like your son, he is becoming more and more fixated on turning on taps all over the house. I have looked everywhere but can't seem to find anything. If you managed to find anything at all, any information would be hugely appreciated.
