Hi everyone, have been reading lots of threads trying to work out how i can add a tap from my mains water - the mains water comes into our garage, 1/2 an inch the tap, 1/2 inch into the wall! so i have no way of adding piping, however on the tap there are 2 x nuts, one i have turned and managed to get out (see pic) - i was wondering if there is anything that can fit into this, allowing me to add a pipe/tap to it. i used 19 mm socket (i think its 18mm).
