Which direction is the sewer of the geomantic house?

The red line in the picture means that water pipes can pass through, and it is forbidden to pass directly at the door. If it is 5 meters away, it is almost impossible. Oh, my God! I forgot to connect to the east and came in. Just connect directly to the red line in the south or north. It is recommended to connect with the north to reduce materials! There are still unknown questions to ask. They are always online.
