Going Up?

There is a debate between the gradient inspector and our building inspector about which way the holes on the perforated pipe need to go in the french drain.

To me, Rob, our contractor and the building inspector, they should go up so that water will go into them and run out through our backyard.

The gradient inspector thinks the holes should go down, which begs two questions: a) how the water will get into the pipe and b) and what's to keep it from immediately running out?

Everything is on hold while this gets resolved.
