90 PSI would correspond to 208 ft of head.

So if you could hold 90 PSI of air on your hose, the water top would be 209 ft above the hose bottom.

Is that what you were asking?

NO.

but thanks for replying



i need to verify that 209 feet above the hose is true,

my boss does not believe my numbers,

pump stops after 10 min, goes dry, current goes down, water does not come out,

as if the pump runs dry,

do not see a check place for measuring the water level,

casong is 6" pump is 4"

thanks
