You just don't get it do you? Aren't you the same chaspul that claimed that your pump had 4,000 psi pressure on it from a tank?
And no, it is not the same as a suction from an underground tank. Having studied what I posted some time ago about shallow well pumps, you are now the expert.
The better quality tanks have all the inlets at the bottom, with an internal standpipe connected to the included float valve. SOME shallow well pumps(but not most) will give problems with a flooded suction, but having the suction taken from the top of the tank to the pump does NOT reduce the static pressure on the pump. Where do you think the water in the pipe goes to when the pump is stopped?
It STILL has very nearly the same static pressure on the suction as it does if connected to a tank. It fact, as I already posted, if you calculate it out EXACTLY, the pressure will be slightly higher doing it your way.
You do what best suits you, but if you are going to come on here with stupid comments, then expect to be ridiculed.
More so when you post comments like the following:
As I said just stating FACTS that can not be criticized by any stretch of ignorance or a vivid imagination.
