I have a walkout basement. I had water problems 3 times during the last 4 years. The first time was after hurricane Isabel. I had 2-3" of water in the basement because the sump failed. The 2nd time and 3rd was due to long time power outage (20hr+), and were minor, as the water just rose over the pump cover.
The backyard is sloped down from the basement door, and the storm water pond (dry when not in big storm) is only less than 80' away from my house. I was thinking to rent a trencher from HomeDepot, dig and bury a 6" plastic pipe from the basement backdoor to the pond to lead away water.
But the lowest point in the basement is in the other end, that is not above ground outside. The sump is there. Dig a trench there means I need to dig a trench 5 - 6' deep there. If I just dig a trench next to the basement door, which is flush with outside grade, I just need to dig 1 or 2' to buy the pipe. Do you think it will work if I do not dig from the trench from the sump? Supposedly I have 4" of gravels under the basement concrete floor, and waster can go away from any exit. I do have the perimeter drain tiles outside the foundation.
