I got a light shock from putting my hand into the sump or DT quite a few times now. Decided yesterday to look for the problem. Got around 90V AC with one multimeter probe in the water, one against the floor. Then switched all off. Voltage gone. Switched everything on one by one. Voltage came back when switching on the power to the ATU.

Anyone has similar issues?

I suppose I have an insulation problem on the switch?
 
that is why it is advisable to use 12V only on the ATU switches. 90V do have a nice byte on it, especially if you are barefoot and standing on the smallest of water splashes.

New ATU coming up?
 
or just stand on a polystyrene box like the guys at exotics lol
one way to keep customers and their little kids hands out of the water.
 
I'll swap you a heater, that leaks 132V. Bargain. Titanium shaft. Used many times, properly run in.
 
90V do have a nice byte on it

ENOUGH TO KILL!!!

Please disconnect and remove the unit, before something happens.

What unit is it?

If you like I could modify it run 12V through the switch, you just pay for the necessary parts for the mod. Safety first!
 
i prefer 220 to 12v as it is easy to know when you have a leak lol
