A yard drain, which is also called as landscape or an area drain, is a very common feature in yards. These yard drains can also be used to drain water from a roof gutter and downspout system out into a yard.
The rain is hammering on the roof and the ponds are forming on the ground. What are the gutters exactly doing? An inch of rainfall doesn’t sound too much but when it falls on a roof it becomes 1,900-gallon torrent flushing off the eaves.
