A certain pump could lift water in a 1 inch tube to 10 feet, but the same pump with a 12inch tube would'nt pump to ten feet would it?, this is my dilema with head/feet :shrug: ...

psi and feet of head are measuring the same thing...

A mile and a kilometre are measuring the same thing, they're not the same though, for one to be converted into the other you have to have two known standards, yes/no?
So danner and Eheim must use the same diametre?, there must be a standard size?, or am I way off base?
...
I'd just like to know what I'm knowing if you know what I mean..., uh?...
PS, I'd pay double the price I paid for my 1250 any day of the week! for the right Iwaki, it's just figuring which pump is right or overkill, good advice on the US/Nippon makes, I'd heard that before but forgotten[doh!]...
