Hello,
Carrying out remedial work on a commercial site and I've come across a metal out building that has a water supply to it. The water pipe comes out of the ground behind the building in copper but enters the building in plastic. There is conduit on the outside of the building next to the water pipe and if I test between the two I'm getting 0.12 ohms. Internally the pipe work is all plastic. Should the external water pipe be bonded?
