Earth bonding pipes

[jpadie]

Hi all

 

Can I ask for guidance on the regs for earth bonding please? 

 

This is for a garden room.  HDPE piping from the main water supply to the garden room.  Copper going from the outside to the inside (150mm). Then copper running in the shower room and utility cupboard using a mix of plastic push fit and soldered connections.  Total length of all the copper end to end is about 5m.  

 

If earth bonding is a requirement then do the regs allow the large 10mm bond to the copper to be anywhere along it's length and then bridge the push fit with shorter spans?  This would make life a lot easier. 

 

Thanks

Justin
