Need to run my sump pump discharge perpendicular to the floor joists. The discharge pipe will be secured across the bottom of the floor joists. The floor joists sit on the sill plate. Any issues with drilling through the sill plate so the discharge runs level to slightly pitched out?
Thanks

What are these "extraordinary precautions"? The pipe exiting the house will be 1-1/2" PVC. Being it's needed to go through the sill plate the pipe will be 4 to 6 inches off exterior grade. The thought was to pull the pipe about a foot from the exterior. Add some splash blocks and a flexable extension pipe to further diect water.
Bear in mind that rainwater will splash upward most of a foot from the ground, so you need to protect not only from rain coming down but from the splashing. And the splashing water has considerable force behind it. And in snow country you'd need to assume that the area would be covered with snow.
There's also the point that a running furnace or just the wind can create a relative vacuum at the opening, sucking in moisture.
You should treat the cut areas with a good exterior primer before fitting the pipe, then caulk carefully the full diameter of the pipe (being ESPECIALLY careful to not miss any part on the bottom), then paint everything with a good exterior paint.
Depending on exactly how your siding is arranged, you may need to caulk UNDER the edge of the siding in the area of the pipe, to prevent splash from working up into the opening.

Be sure to get the water past the foundation overdig area, otherwise you're just running the same water through a cycle.
