Hi guys,
II have a problem of 1 item putting current in the water. I live in a old 70's french house (220v).
Responsible of the leak is a ATO system made by me. Is a 12V membrane pump connected to a float switch and a PSU. The PSU is a 12v 5A PC style psu (with 3 pole wall plug).
The only solution that i've found is to put a titanium probe and that solve the problem of current going thru me (isn't that hard but if i have a cut in the hand and i'm bare feet, i definetly feel it and also quite annoying (i would not say strong, but if you don't expect it you surely pull out the hand fast)
What can cause the problem? Any idea in how to solve it? I've tried 3 different PSU and 2 new pump and the result is always the same.
The pump and the switch are as in photo:
