As I said prior....not going to debate...so I will sign out with a few comments on this, as it has been twisted into a complete fuster cluck.

I didnt blast anyone one......thicken up.
my inputs were based on flow vs filtration aspects.
if you read the comment about pumps dont suck....you will see it contradicts itself.
atmospheric pressure and barometric pressure is the same.......so unless its at the nominal 29.92......it isn't 14.7
But I wouldnt know this since I have never done any research would I Monte?
