Hope someone maybe able to help with these queries.
Main Bonding Incoming water main is in mdpe coming into the kitchen. It then has a copper stop tap and runs for about 2-3m in copper, mainly behind units, apart from top half metre as it enters into the loft (single storey). At this point it becomes Hep20 plastic and remains so throughout the house. Does this piece of copper pipe require bonding?
Supplementary Bonding In bathroom. Central heating pipes run as Hep20 plastic under floor and then tails above floor to towel rail are chrome plated copper (100mm ish). All domestic water pipes are in Hep20 plastic. The bathroom has ELV downlighters, a shaver socket and an ELV extract fan set into the wall (transformer located in loft above). All these are served by the same lighting circuit. There are no other electric points or services in the bathroom. Is supplementary bonding required?
NB the lighting ring is served by a 6A MCB and an 80A 100mA RCD. (TT installation)
Can you explain why even if the answers are no. Many thanks[/u]
