    Lead water lines have also been known to be harmful since ancient times, though this is contested by industry trade groups within the United States. [5] [6] Lead pipes were preferred over iron pipes because they lasted longer and were more flexible. [7] Lead gooseneck connected to a steel pipe Lead service line connected to residential plumbing

    en.wikipedia.org/wiki/Electrical_wiring

    In Austria, wires were concealed by embedding a rubber tube in a groove in the wall, plastering over it, then removing the tube and pulling wires through the cavity. [ 15 ] Metal moulding systems, with a flattened oval section consisting of a base strip and a snap-on cap channel, were more costly than open wiring or wooden moulding, but could ...

    A chase nipple is a short pipe fitting, which creates a path for wires between two electrical boxes. A chase nipple has male threads on one end only. The other end is a hexagon. The chase nipple passes through the knockouts of two boxes, and is secured by an internally threaded ring called a lock nut. [1] [2]

    It then reverts to a lower sacrificial current, while harmful negative chloride ions migrate away from the steel and towards the positive anode. The anodes remain reactive through their lifetime (10–20 years typically), increasing current when the resistivity decreases due to corrosion hazards such as rainfall, temperature increases, or flooding.

  9. Electrical conduit - Wikipedia

    en.wikipedia.org/wiki/Electrical_conduit

    Unlike water piping, if the conduit is to be watertight, the idea is to keep water out, not in. In this case, gaskets are used with special fittings, such as the weatherhead leading from the overhead electrical mains to the electric meter. Flexible metal conduit usually uses fittings with a clamp on the outside of the box, just like bare cables ...
