I have also had this experience.
A double storey house... with a pvc drain... the water was leaking and running down the drain onto a conduit pipe and down into the ground floor DB
I did run an earth from various plug points to check continuity and an earth from the main and sub DB's to check the earth.
The earth point on the meter was finger tight ...the geyser bonding was done by twisting a wire around the pipe which got painted... and bonding straps between the steel drains on the old part of the house had been broken off... no lugs used on the earthing... the list just goes on.
