Gary,

Manufacturers ratings are based on an unrestricted flow with little to
no resistance from the piping.
In other words, they use very large pipes for the size of the pump
outlet. Normally more than double the size of the pump outlet!

I would have guessed wrong. I thought that the pump would be tested with the
same size hose that the connection called for. This is misleading..!! Makes
it tough to choose a pump properly. I will stow this tid-bit of information
for my next installation.
