oomis: It is very possible that the local Vaad is “reliable and accepted”, but follows a psak in a specific Halacha that is not according to your Rav. “
Nope. In my neighborhood and its environs, my Rov, as EVERY rov in the neighborhood, is part of the local Vaad. They speak with one voice, after making their decisions together, regarding the kashrus in the community. Even if an individual rov held differently for whatever reason, he would not officially voice that to his congregation, and it is more likely that the dissenter is more meikeil than the Vaad, not vice versa. We had an inyan where my rov was clearly very uncomfortable with an announcement that the Vaad had all the shuls make one Shabbos regarding a particular place of business. I understood the reasons for his discomfiture, but he nevertheless made the announcement just as the Vaad instructed, meaning that this is what we have to do.
