Addition of new Patio
We are in the design stages of adding a new 375 sq ft patio in the backyard. Unfortunately, a significant portion of the mainline (and electrical wire) will end up in the way. Do I move the mainline out further so it goes around the patio, or take my chances on having the patio above the mainline and wire, or run the mainline and wire though a PVC pipe and keep it underneath the patio? Also, Is it easy to splice the wire (18-13!!) and extend it out?
Please help!
