I'm adding french doors to my basement and creating a walkout. The doors will open to a stairwell of 6 or 7 steps. Since the stairwell is exposed I know I have to install a drain. My question is this: Can I connect the drain at the bottom of the stairwell into the drain tile pipes? The drain tile collects foundation water, send it to the sump located in my basement and then pumps it outside. Any thoughts would be appreciated.
