Years ago when I ran the line to the barn, my neighbor who dug the trench, directed me to lay the pipe in a series of shallow S curves to allow for settling and movement.

A few years back, I had the first break due to drought, and the ground shrinking/moving and causing a break on a coupler. I dug the break up, and didn't know how to fix it, so called a plumber. The guy explained to me how/why to create an expansion loop to provide some space for the pipe to flex, and also to backfill with sand to allow better movement than our clay soil that gets hard when it's dry. It's been my practice since.
