I have a down spout that exits to an area that tends to pool water. Unfortunately the flower bed area near the house is lower than the surrounding grass area - and that grass area slopes back towards the house/flower bed.
I do plan to address that slope issue eventually but wanted to divert the water coming out of the spout first. All I have read is about putting in underground drain pipes.
What if I simply just want to run it above ground, wrapping the house for about 20 feet and exiting at another area that is more properly graded? Is that not good to do?
The secondary question would be whether I would need to pay particular attention to what type of pipe I would need to use. Smaller is obviously nicer but not necessary.
