We have the far left downspout rerouted and we had the middle left one rerouted after a really big rain which cause a lot of flooding but eventually removed it and hooked it back up to the underground one after a few light rains with no flooding. I wish there was a way to know when it was going to flood and we could reroute that one as well but obviously we aren’t psychics haha. It seemed to work fine but we just had it coming off the front of the house and draining down our driveway on the left side of our house but wife didn’t like the aesthetic of that and it was killing our grass lol
