TOP BAD!! been there done that water can and does come from below
footer and work its way thru your basement floor.

the underground drain to daylight is ideal, i would add a perforated
line or two around your basement under the concrete floor for best
drainage if your sump s a single point entry. this also allows drilling
or snaking line ud=nder home to be not perfect location wise.

also price backhoe digging outdoors and run line under floor tearing up
some concrete. you dont necessarily have to get the line to the sump
pit, water finds its own level anyway. just so long as it spills out
from under your home.

daylight drain is the way to go!

Been there went thru this......
