Thanks for your input. We have a 34 foot run, and we need to run the water all one way, because at the back end of the garage there is no place to go with it.
The garage and house are about 3 feet apart, and run off from the garage currently drops between them. At the back, a downspout would have to cross the sidewalk leading to the back door, or go across the back of the garage where there is an entry door. >From one of your figures, if we could get a one inch drop over the 34 feet, that should be enough to get us by.
