SESD | I have a 12" outlet into a creek. There is a driveway next to the creek and field is on the other side of the driveway with a 12" surface inlet to drain the water held back by the drive. When the creek is full, it backs up and pushes out the inlet into the fiels. Is there some kind of a check valve or backflow divice that can be used on a pipe that large? Other ideas? | |
