Quick question:

This week I am planning to run black poly water line out to barn and pastures from the house.

Will be starting from a 3/4" copper line from the pressure tank in the basement (& installing a shutoff valve), then go through the basement wall, and then trenched 3 ft deep all the way out to the barn.

Longest run is a good 550 ft. or so.

QUESTION: What diameter of polyethylene to use? 3/4"? 1"?

Fyi, there's 1" black poly from the well to the pressure tank in the basement of the house, then from the pressure tank to the spot where I can tee off from is 3/4 copper. The hydrants themselves are 3/4" diameter inlet.

Is there ANY benefit trenching 1" poly over 3/4" if both the source and the destination are essentially 3/4"???

Will my water troughs fill up any faster?

Thanks!
