    What's the best way to get the "fixed left edge" on these rotors to line up with my property line? For instance, if my desired position is 12:00 and the rotor's left edge points to 9:00, should I back off the rotor 3/4 of a turn, or really (cross my fingers and) torque it down another 1/4 of a turn? All of my fittings are plastic, and I've already broken off 1. Or am I missing something all together?

    Plastic to plastic needs to be only hand tight in most situations. Possibly 1/2 turn with wrench. If you follow that rule, you can get away with turning further in to the correct position.

    Loosening a connection possibly allows for a leak, but the pressure on sprinkler fittings is low, and not usually a problem.
