electricity in water

Can a PS generate current into the sump that it is sitting in ? Last night
I was able to put my hand into my sump, now, 8 hours of running time later,
I get a mild, but nonetheless unpleasant shock that does not seem to
discharge or kick my GFCI.

Any ideas ? I don't think troubleshooting this is going to be easy. I guess
I could use a multitester with on probe in the sump, but where would I put
the ground ? If the voltage was being caused by a regular electrical short
then the GFCI should have tripped but it did not. So, where do I put the
ground from the voltmeter ?

ok, never mind, seems like the problem is in the Mag 7. I swapped it out
for another Mag 7 and it didn't shock me. What a crappy way of testing for
the problem...ok, stick my finger in the water a little bit and see if I
feel anything, nothing ? ok, put my whole hand in, no shock, ok, found the
problem. It was only a little shock but enough to let me know that there is
a problem.

LoL. I would suggest that next time you have that event, try pressing all plugs
into their respective outlets firmly and see if that doesn't make the "shock
test" easier to perform.

Marc,

I am not sure if you are encouraging me to press the plug in harder to
allow the pins to make better contact for more voltage or better contact for
the ground pin and I am almost too scared to ask. Instead I am going to go
get a new Mag 7 and send this one back to Marine Depot on Monday.

Any idea of the other Mag drives, like a 9 or higher, can suck water from a
lower point ? I guess it would need to have a bleed valve to let the air
out.

Yes, I'm talking about pushing in the plugs a little more firmly. I was
getting shocked by my tank for a week, and it turned out to be the 6-way outlet
wasn't plugged in all the way. Talk about a simple fix!!!

However, if your Mag drive is defective, send it back! I had to do that myself.

You mean have the pump not submerged, and have it draw water up into it? You'd
have to hook up some type of p-trap and a vent to keep some water in the pump at
all times, and that is something I've never tried to do.

This one is submerged but another Mag 7 I have on a different tank was
suspect in warming the water in the sump. (it was only a suspect as the real
culprit was a Rio that had it's intakes partially blocked)

I was hoping that one of the other Mags might be able to suck air and water,
allowing the pump to sit at the same level as the water level in the sump,
with a pipe leading from under the water, up and over the side and then back
down to the pump which would be sitting on the same surface as the sump. I
build the pipe but as soon as I turned on the Mag I remember that it was a
centrifigal pump and was not going to be able to suck the air through the
pipe. Anyway, to make a long story short, the pump went back into the sump
and the heating issue was resolved another way. I just wanted to know if
there was a way to locate the Mag outside of the sump, somehow drawing the
water up and then down to it.

As far as the Mag with the possible short/leak, I am no longer interested in
testing the problem. I bought another Mag7 and replaced the bad one. If my
conscience allows me, I will just return the faulty one claiming it was the
one I just bought today and that it was shocking me. I have spent a few
thousand dollars there, I don't feel bad and according to the guy in the
store, they will just send it back anyway, so no skin off their back, I just
won't have to deal with a long phone call with Marine Depot.
