HELP.. My RO-DI water electrocuted me

[Delphinus]

Ok, it's still weird, but it sounds more like a static discharge to me. Now if this happens every single time you touch the water, then something is REALLY weird. But I think maybe you had a charge yourself built up and then touched water, it could explain the zap (and likely anytime you touch water now, it will be probably be fine).

A shock from stray current is a continual zap-zap-zap-zap-zap-zap-zap kind of throbbing. A full 110V can hurt a LOT, and affect your motor abilities such that you might even have trouble backing away from the source of pain. It may only be milliseconds worth of contact but it feels like a really long time.

I used to think that every little tingle I felt when I put my fingers in the water was some kind of stray current. But ever since I had a Rio go on me (and I didn't know, and I had put my hand in the water and felt a full 110V), I can assure you, there's no comparison.

At least in my experience.

I would suggest that you get a voltmeter or something and make sure there's no capacitance (or whatever the term is) in the water before you stick your finger in there.

But basically, if there's no metal contacting the RO unit and you're connected with plastic tubing and all that, there's no reason there should be any charge in there.
