Adding outlet on back deck. We are tapping power out of the existing circuit in the living room. Outlet is located on opposite side of the wall as the new GFCI. We installed a new in-use cover on new GFCI so that cord can remain plugged in and still be water tight. We will tap power out of the new outlet we installed and pipe over to the pool pump and install a perm post with a weatherproof outlet. This will avoid the need for an extension cord.
