It did cross my mind  the condo has a open undercroft about a meter high so I suppose it is technically feasible.

Yeah, that's a shame, I've seen units that take an earth to the board then no further.

 

Task A is to talk to the condo management to see if they have a sparks available, then get him to look at the issue. 

 

The risk of corrosion to the pipe is small with AC, a DC current is a whole different ball game (there can be significant problems with DC traction railways), but as noted earlier if they replace the pipe with plastic ...

 

I would also think about adding earth-leakage protection to that board.

Many thanks for all your help. I will do as you suggest and update the thread when I have a response.

The only problem you could have if you use a metal water pipe, is what happened decades ago in the UK when metal water pipes were used as earths.......very often some of the pipes, or part of the pipe network were replaced with plastic pipes and fittings, so you didn't have an earth in effect.

 

The other thing was that if many people had used the same metal pipe as an earth, then if there was minor leakage to earth over time, using that pipe, then it would corrode the pipe and you would get a water leak.
 

So being on the 15th floor sounds fairly problematic. We were getting used to having cold showers and we could take the unit back if it all proves undoable.

Is that pipe available inside the condo?

 

Also, is this a rental unit or yours?

 

And, of course a photo of the board with the cover off (care please).

We are the owners - the pipe is outside the unit in the corridor.

Cheers here you go ....

Many thanks for your quick replies sounds like one to have a word with the office. Here's a couple of photos.
