Is there an easy way to tell which is the mains pipe feeding the cold water tank other than working back from the tank itself. (which is very difficult in my house!)
I am wanting to install an electric shower on the mains riser, but there are about 6 copper pipes in the area that I want to splice into and don't want to cut the wrong one!
Thanks
