[QUOTE="binky, post: 287564, member: 490"] IMHO opinion the additional bond is probably unnecessary due to fact the pipe has more copper in it than the bond wire. No harm in having it but over a short span a bit pointless (bit different if down opposite end of factory perhaps?) As for the bathroom, given full RCD protection, and meeting the relavant criteria in regs, I wouldn't have thought it necessary to bond at this point - again I would argue pipe has more copper than the bond wire ergo any fault current would travel down pipe first to your MEB anyway, though parallel path would help some more in meeting the stuff about touch voltages and disconnection times - regs book at work, otherwise I would quote section that applies (4 I think, but that might be previous version). Wander lead test from bathroom to MET (or did you post you've done that already) [/QUOTE]
