yes its corrugated pipe, holes are on the bottom. the weep holes in the block were clogged and when we punched them back out water started pouring out. the old pipe was just the black pipe with slits and they were full of silt.
the way my house is build my sump is only there because of code. i have a walk out basement on the side of a hill so they don't drain into the sump they run out behind my house to the creak. we ran water for over 2 hours cleaning out the weep holes and making sure the outside drains were clear. we ran a hose up the pipe in the sump and it "T"s off to the outside drain.
didn't even think about calling or i would have.
