Air infiltration through sump pit
Ran a blower door on what should be an extremely tight home. However I am getting significant leakage through the sump pit which is essentially connected to the outside via the drain tile. (grading has not been completed on the property) I found some other air sealing to do, but i have never run into this situation. Do I need to wait for the grading to be done, or have the sump pit sealed?
