..... Too late! .....


The experiment has been done. The vac cleaner (unmodified) was plugged
into the mains (240v), and the pipe stuck in the water tank. This is
not a wet n dry vac!

It pumped the entire contents of the 1000 gallon tank out sucesfully.
The water went up the inlet pipe, thru the impellor, directly thru the
motor running on 240v mains, and out the back end. And it did the lot.

And it still works now. No series limiting resistance, no reduced
voltage, nothing.


And now I'm gonna confess something It had already been done
before I started this thread. I wouldn't have claimed it could be done
otherwise I didnt do it, its a barking idea, someone else did it,
and the vac still works fine afterwards.

You were so convinced it wouldn't work. You were convinced, even tho
you hadn't done the experiment and could find no convincing
theoretical reason that would stop it. You were also convinced it was
dangerous: it is if you just plug it in, tho with proper earth bonding
to case, water outlet and inlet, it can be made safe. It just operates
as an electrode heater, which is standard industrial kit.

This all tells me something about people, emotions, assumptions,
logic, and showmanship.

PS dont try this at home, ever.

Bullshit, I'm gonna try it at home.
How clean was the water? How good was your power source? No way it
didn't blow a standard 15A fuse, was it done at a farm running from a
weak diesel generator 2km away hooked up with bell wire?

Me too, I never said it wouldn't work, couldn't be done etc ...
If it can satisfy a perv, surely it can suck a pond dry

Anyone got an old tube vacuum cleaner they don't want?

Would that work, or would all the water still end up in the vac?

Add in a float valve cutoff to stop water going in the motor when the
level goes too high, and you've got a Vax/Aquavac type wet & dry
vacuum, so yes, this does work.

I know it wouldn't work here, and I live on a farm too!
My RCD's are checked regularly and wouldn't allow such abuse.
Current from either live or neutral must return to each other and not earth.
Even with good earth bonding, the earth has significant resistance
(more so this dry year), and dangerous voltages can be established
between the earth point and where the operator is standing.
Did he put a finger in the water to check?
(PS do not try this at home!)
Any industrial system would be double insulated from real earth.
When was his wiring last checked?

I thought I'd continue in the same vein as the previous two posters by
misspelling the one important word. ;-)

I caught the previous poster's mispeled words, but didn't make the

And, BTW, the answer is "freeway".

I was there once. I'm happy to say it was about 30 years ago and I
haven't had the need to go back. I *certainly* don't have the want.

This got me thinking. Other than US and Cnada, is English an official
language anywhere that is not an island.

In case you hadn't noticed, English is not the official language of the
US either. Unfortunately.

not a clever idea. Do it wrong and it could kill you. It really _is_ a
stupid thing to do. Most vacs are 2 core, in which case the water will
spew out live. eevn on a 3 core machine it may come out live,
depending on construction details.

How clean was the water?

1000 gallons of rainwater off the roof.

How good was your power source?

240v mains, straight off the grid

No way it
didn't blow a standard 15A fuse,

correct, since we dont use 15A fuses anywhere in such circuits

was it done at a farm running from a
weak diesel generator 2km away hooked up with bell wire?

no, 240v at the vac.

funny you should ask that

Who knows. No RCD anyway.

Don't try this at home, seriously.

Knife? This is a DIY group - SDS drill shirly

Jesse or Ace? ...or perhaps you meant venturi? ;-)

Ace, hands down!
