    Foffer:

    Are the hot and cold supplies to the pump  properly earth bonded?




    The cold feed is from a plastic loft tank so is not an extraneous-conductive-part, or an exposed-conductive part as it can not be touched.


    The hot pipe is well bonded by previous installers who bonded just about every copper pipe in the airing cupboard, including the shower room metal radiator pipes and the pipes to the heated towel rail above it. All is good.
