Counterintuitively, you usually want the holes in drainage pipe to point down, not up. This way, water from below can get forced up into the pipe from underneath, which then has a low-resistance path to flow away. If you install a pipe that only has holes on top, the pipe will want to float on top of whatever water is there, until the water level covers the ...
