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
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.
