I am running drain tile that is draining a roof area of approx. 680 sq feet. I have installed 4" tile for this run, the total length of the run is about 80 feet. I have another area of roof that I am draining that is approx. 640 sq. feet, this would tie into the other run at about the 60 foot mark. If I try to tie these two runs together would that be too much for a 4" pipe? Should I run them parallel to one another rather than join them? Also if I maintain a 1/8" drop the drain tile will never make it above ground, the top of the tile would be right at ground level. This being the case what is my best option for dissipating the water? I have seen talk of using popups, I have also considered excavating an area and filling it with gravel to do it. Any other ideas or options?
Thanks
