Main water Bonding

[EddieB]

If the incoming water main is plastic can I assume that there is no need to run a 10mm bonding cable to the stop cock

As long as there is metal pipe after stop cock, bond it . Ive seen people bond the plastic pipework before and it all ended in a big puddle .

Hi.

Even though the incomer is plastic chances are carrying on from there will be copper, so I would run a bond to the stop cock.

Cheers.

remember to bond within 600mm, consumers side of stop cock

Only if the installation is plastic also.

I thought the point of bonding the incoming services to the MEF was to ensure that if parallel earth paths exist the ZS is improved at the board which enhances ADS. If the incoming is plastic goodbye parallel path path????

What about combined installations? Those that have both plastic incomming and some copper and some plastive. If you boneded the copper it would only bond untill it reachs a plastic fitting. In fact the whole house could be done in copper but if plastic pipes are fitted then its useless.

If the incoming from the St is in copper then fine I beleive that the point of the bonding is to asssist with ADS which the parallel path will do, not for supplemtary bonding of the copper pipes within the dwelling am i right in this??

Chaps,

Basically, bonding is to prevent voltage appearing through the underground pipework.

If its plastic, it cant get in.
