poor surface drainage or problems with
gutters and downspouts, you are inviting
rainwater into your basement. Drainage

surface water. If water floods around your
basement, water will come in.

have a sump pump. A sump pump is designed to
collect the water from your basement drain
tile system. Water can back up from this
sump pump if the electrical power goes out,
the flow is too great, the discharge is
blocked, or the pump malfunctions.
This storm water may overflow the sump pump,
run down the floor drain into the sanitary
sewer, and/or flood your basement.
leak into your basement because of poor
surface grading or problems with gutters,
downspouts, and sump pump discharges. Leaks
can also be caused by problems with the
palmer valve, drain tile, storm sewer lines,
or window wells.
