Voltage in shower waste!

[Tridentsystems]

So is it there constantly or just when waste is full of water ?

 

[purplemaf]

Just when the water is going through the waste. I can watch the voltage reduce as the water disappears

What dangerous voltage levels are we talking about here !!!!!!!!!!!

18V well below the level of detection by touch!

Really difficult to know what's occurring here and advise!







How about fitting a metallic waste trap on these shower basins and bonding them to the shower mixer taps... :ninja::38:

 

[purplemaf]

If that were the case I would never have had the call....I have felt this shock and it can certainly let you know it is there!

Ive been through the idea of having a metal waste put in. First plumber ive spoken to tells me metal traps dont exist?? I'm also not so happy to conclude with that idea as that doesn't answer the problem of where its coming from.

Is the voltage there if the water in the waste is from an external source (bucket of water) or just when it comes from the taps of the installation?

Thanks.

 

[purplemaf]

Fair question. It is literally in the tray/basin with the taps/shower turned off and water draining.

Someone did ask earlier, how exactly did you test for this voltage.
What instrument did you use, where did you test from and to, including multiple locations of both points.
Only asking because it may shed more light on the problem.

I'm also assuming that the shower taps are fed from a remote boiler, i.e., not a local electric shower.
