I have a very basic question.

I'm connecting a length of galvanized pipe with a 90 degree elbow that connects to another length of galvanized pipe. I need to ensure the elbow points in the proper direction to match up with another elbow 10 feet away. If I tighten the elbow as much as I can it points the wrong way.

Is the proper procedure to tighten as much as possible and then to back it off a bit to achieve the proper angle? And rely upon pipe compound for a water tight fit ?

Thank you.
