1.2kohm from stop tap to met although fed by copper pipe and then plastic pipe.

hertzal123

As above a 1 meter section of plastic pipe joins onto the lead watermain under the floor,whilst the gas supply

pipe passes through a brick wall and awaits the gas meter to be fitted.My thoughts are that the gas pipe through

the wall is giving the low reading,but could the water in the plastic also be contributing since it connects to the lead?

Gas and water pipes are glanded into the boiler,which is not electrically connected atm.I have main bonded gas

and water,although in theory the water does not need bonding.Thanks for any advice.

    1.2k seems very low for 1m of plastic pipe - I did some experiments a few years ago and (from memory) was getting around 15k from a single push fit fitting between two pieces of copper pipe - i.e. through just a few mm of water.  I suspect there's something else providing a path somewhere - is there copper after the stoptap and does it go anywhere near damp masonry or back underground (e.g. to feed an outside tap)?
