AAaaahhhhh. The Bonding Question Again.

Zoomup
Do we main bond up an installation if a new gas boiler is to be installed when the old one is removed?


What are extraneous-conductive-parts, and what are not?


Now, to put a spanner into the works, do any issues arise if the copper pipes are "bonded" with solderless copper bonding?


Otto von Guericke would have known this for sure.


Over to you?


Look......

    No, the true earthy sections may not be bonded if the copper pipe has glued joints where they are electrically insulating by virtue of the new copper glue (Super Power Solderless Copper Bonding), if it not electrically conducting.



    You seem to be assuming that the pipework system is only bonded once (e.g. at the stop cock) - if you bond each pipe as it emerges from the (solid) floor (as you probably should) - then glued joints don't matter (or plastic push-fit or section of plastic pipe, or ...)

    But we don't main bond every pipe as it emerges from the floor do we? We often assume that electrical continuity exists, so if a copper joint is glued as opposed to being soldered, it may be missed, as it will appear to be a neat soldered connection and electrically continuous. I have encounters in many older building that have all sorts of pipes in strange locations, metal water pipes, metal gas pipes, metal oil pipes and other extraneous-conductive-parts, some in bathrooms and shower rooms downstairs. So we can't assume electrical continuity of copper pipes that have been glue jointed.
