Bonding of cast iron toilet waste??

[Underpaid]

Has anyone ever bonded a cast iron waste pipe? and if so what were the circumstances? Can u buy some kind of freaky long bonding clamp? As it states in the regs not to join two clamps together.

Years ago worked in my sisters house in Kent, it was a old farmhouse.

The first time I had encountered a TT system , and never have since.

I had to put in multiple rods to get Zs down and local electrician came round, used to working in that area, tested them with his probe meter into ground.

But their was a cast soil stack , and he made me bond it like a main gas/water pipe, as remember having to run a very long cable through the house back to the board and it was not an easy run.

Never knew you could get massive earth clamp, but local electrical place said it was really common in that area.

Also made me supplementry bond it to rest of Bathroom pipework.

But as never encountered it since , never thought about it, until seeing this thread.
