Well ,I wasnt wanting to actually perform the experiment
but you leave me no choice.

I personaly think the vacume in the top will cause a lower pressure at the bottom than the weight of the water could present to the bottom.

after all a 1" pipe can do the same job
and a pressure guage is cheap.

the whole test will cost no more than $10.00

and I can use a 10 ft lenght of pipe.

this way I can put this to rest and if you dont agree with
my findings then you can perform your own test.
