When young my father often had me along as a helper when installing washers & Dryers. In those days most wall outlets were two prong instead of the three prong grounded outlet. Also in those days plumbing was all metal pipe, coper or iron were the most common. He would install a clamp on the cold water pipe and run a wire to the washing machine & dryer when needed.
