Following comments on my other question "how-an-open-succah-oriented":
Let's imagine one is facing a new Halachic reality he never heard of: he always built Succah on his 5th-floor balcony and then moved to a private house with the opportunity to erect a Kosher 3-wall Succan in his backyard. He doesn't know, however, whether its orientation might be a Halachic issue or not.
Should one contact a Rabbi or assume anything will work? What do our Rabbis think - do they prefer their students to consult them in doubtful questions or not?
