Is the gph measurement with zero resistance? if yes, what is the gph with the hose?

I think you better call seaflo for those answers

Is there any way to test the auto function? For example manually moving the float or sensor without using water to make sure that it will be activated

I've bought two of them and they work excellent no need to test it they tested already just buy it it's a great great value for the price low profile

It is automatic, so it won't run dry for more than a second at a time.

What size discharge line is recommended?

This unit has two different size outlets for the outflow of water right off the pump you can use either one I would use the bigger one I believe it's 5/8 I'm not sure if it's 5/8 and I run a 5-800 right after you discharge works good
