Electrical bonding to lead water supply pipe

hatt55

Well, the job is done and I have water again! 

It was a different engineer, who decided not to use a plastic stop tap. Instead there is now:

Lead (sticking out of soil) > Copper (short) > Stopcock > Copper (short, with bonding reattached) > Plastic > Copper (going off into the subfloor darkness).

Its seems like a lot of joints, but he gave a reason for not being able to solder the copper bits together, hence using a little stretch of plastic in between.

So based on everyone's comments and possible different interpretation of the regulations, this now has a chunk of plastic which would insulate the supply pipe from the rest of the system. There is also a bonding wire attached house-side of the stopcock as before, although this is now clipped to copper pipe rather than lead. This seems to replicate the previous set up other than that there is now no bonding attachment on the street side of the stop tap/stub of lead. 

I called my electrician prior to all this being done, and they did say that the bonding clip should be on the house side of the stop tap. So hopefully all is ok!
