Hi, my rising main enters the house through a solid concrete floor near
an internal wall in the kitchen. It has a black plastic compression
type coupler near the floor which joins it to a length of blue plastic
pipe about 25cm long onto which the tap connects which then connects to
all the internal plumbing (on copper pipe). Wondered if anyone could
help with a couple of questions I have: 1) can the copper pipe above
the main tap be used for earth bonding given that the blue pipe it
connects to described above appears to be plastic (i.e. no continuity
to earth?), and 2) does the blue bit belong to the water board or can
it be replaced/extended given that it is in the most inconvenient
position possible bearing in mind the way the missus wants the kitchen
to be... Sorry if these are dumb questions, by way of reciprocity I can
tell you just about anything about data networking if you have any
questions (unlikely :o)
You do not say what sort of pipe enters your building before the black
connector. Your description suggests lead pipe with the black connector
being a converter to metric sizes of pipe. Regardless of this as your house
installation is done in copper then main equipotential bonding is required
(note the lack of the word earth). I would suggest a 10mm earth cable back
to the earth busbar in the CU from the copper pipe just after the tap just
as as you suggested (reg 547-02-02 applies)
, and 2) does the blue bit belong to the water board or can
As far as I am aware you are responsible for your water supply pipes and
internal stop taps from the stopstap in the street that controls your
property. You have to replace and repair them at your own cost (although
some companies may do it for free) but yes you can extend the pipe.
Sorry if these are dumb questions, by way of reciprocity I can
have put the ceilings back up I will be asking.
