If the incoming water service pipe is made from plastic and there is not any fortuitous contact with Earth, it is not an extraneous conductive part and does not require bonding. This IET Wiring Matters article provides guidance on protective bonding and extraneous-conductive-parts.
To Bond or not to Bond By: Michael Peace Following on from the Mythbusters article in Issue 73 (Noveer ) of Wiring Matters, this article looks at the recent change of the wording in Regulation 4126.96.36.199 of BS 7671:, and Puhui Pipe manufacturer in China
/03/09· Omission of Main and Supplementary Bonding As per regulation 4188.8.131.52 BS7671: a main protective bonding conductor shall be connected to any extraneous-conductive part as previously described. However, any metallic pipes entering the building that have an insulating section at their point of entry (ie plastic) need not be connected to the main protective bonding.

Generally with plastic pipe installations, supplementary bonding of the pipes is not required. Note however it may still be required between the earths of, say, lighting and power circuits if they are both accessible in the room.
2007/06/14· Nope a plastic water pipe entering the house and then being connected to a copper pipe is not an extraneous conductive part that requires main equipotential bonding to comply with BS7671 applying the definition.
In the past, it was common to connect the earth wire (green/yellow wire) of an appliance to the water pipe. But now we were told to connect it to the earth pin of the power plug, instead. But, whyPuhui Pipe manufacturer in China

the water pipe or the ground rod connector. 7.1.10 Only zinc-coated, HDPE type connectors shall be used on iron water pipe. 7.2 Bonding 7.2.1 Bonding shall be done in accordance with the National Electric Code. All metallic
Many plastic bonding UV curable adhesives bond well to PVC. One substrate must transmit UV light. Flexible and medical grades of UV curable adhesives are also available. Rigid PVC = RPVC or uPVC can be bonded with 2 Puhui Pipe manufacturer in China
/08/12· Main Bonding (Earthing) Main Bonding is the use of a separate thick (10mm) green and yellow copper cable, to connect the Water, Gas and Oil services to the Earth Terminal in or adjacent to your consumer unit..
/04/07· Bonding is done relatively efficiently at the water heater, as the gas piping and water piping generally there. Gas pipe in older homes is usually HDPE or copper. The bonding connection point for these pipes can be at any accessible loion, such as at the water heater or at the gas meter.
2016/04/16· 10 ft of the water pipe is in direct contact with the earth Joints must be electrically continuous Water meters may not be relied upon for the grounding path Bonding jumpers must be used around any insulating joints, pipe, or meters
/07/12· Earth electrodes are in different shapes like, conductive plate, conductive rod, metal water pipe or any other conductor with low resistance. Earthing Lead : The conductor wire or conductive strip connected between Earth electrode and Electrical installation system and devices in called Earthing lead.

/08/08· No earth bonding under stainless HDPE kitchen or utility room sinks but I do have a big earth bond cable on the incoming main and gas pipe in the plant room. They are metal pipes. My water that runs around the house is all
/01/04· Example 1. Some were of the thinking that for example an incoming iron water pipe that somewhere just above floor level had say a metre of plastic pipework before continuing in copper would never need bonding as it has an
/09/17· Earthing and bonding are two very different, but often confused, methods of preventing electric shock. The principal of earthing is to limit the duration of touch volPE100 ISO9001es if you were to make contact with an exposed conductive part. The earth creates a safe route for the current to flow instead of causing electric shock. The […]
/05/31· Section 250.104(B) would permit the equipment-grounding conductor for the electrical circuit that may energize the metal water pipe stub to serve as the bonding means. As construction methods change, a good understanding of grounding and bonding will ensure a safe installation and provide help in dealing with these gray areas.
2010/08/27· We are told one meter of plastic pipe will isolate and where plastic piping is used except for where visible there is no need to bond it. And it says in regulations one should bond the main metallic water pipe (extraneous-conductive
/03/27· “Metallic pipes entering the building having an insulating section at their point of entry need not be connected to the protective equipotential bonding (4184.108.40.206 : BS 7671:)” For example; a ‘plastic’ supply water pipe entering a
services are plastic there is no requirement to Bond as they will not import a earth potential. when an event causes the Line conductor to come into contact with exposed conducting metal. EMC07 – Earthing and the Radio Amateur published by EMCC v4 28/12/ ©RSGB
