I have a large cupboard under my stairs/hallway,
I want to make a washing room.
there are lots of pipes running up the wall, the 15mm are all hot and connected to the heating, there are larger 22mm pipes which are cold.
i need to connect a washing machine to the one of the cold pipes,
does it matter which pipe i choose?
would it be best to say, trace the pipe to the cold bath tap?
