I've got a basement flooding issue and I'm asking around to try to
figure out what to do. We have a rain gutter downspout that drops
into some PVC that goes underground for drainage. 3 feet away from
that I have a basement window about 16 inches below grade in a window
well. At the bottom sill of the window outside is 4 inch perforated
PVC put there I guess to offer some sort of drainage.
There is definitely a connection between this PVC in the window well
and the gutter drainage system. When it rains this PVC begins to fill
with water. No problem, but when it rains really hard the PVC fills
up and water starts flooding out of the perforation holes. The window
well completely fills up with water and it starts pouring into my
basement through leaks between the window and frame.
I'm thinking that the gutter drainage system is backing up and
flooding into this PVC pipe that runs along the window. If I'm right
about this I have a couple of questions: What was this PVC running
along the window meant to do? There are gutters up above so it stays
dry in that area. Also, is there some way of getting that gutter
drain to accept more water without digging the whole thing up to clean
or reline with gravel? Thanks very much, Alan.
