Yes. I am shocked that you are asking that question. Please do not think that 1 inch would be a performance improvement over 1-1/4 in any way.

I consider calculating pipe size the hardest part, not the actual work. I really appreciate all your posts Reach. I'm going with 1/1/4". I already have a 300' roll of 1 1/4". I bought 200 PSI CTS. Did I make a mistake? Should I have purchased IPS? I think the inside dimensions are the same, but the walls are a little thicker on the IPS.

You have it backwards, but it doesn't matter. You have the 1-1/4 CTS poly, so use it in good health. You WILL purchase waterworks compression fittings for it, that include the stainless-steel internal stiffener, as there is no other usable choice available. (insert fittings are definitely not sized for CTS poly tubing)

It looks like 1-1/4" CTS has a 1.05" Inside diameter.

So the chart below for 300 feet, more closely would be for the 3/4" meter, and 1" pipe.

In the 70's I run 350 feet with 1" poly and was a bit stunned to see how little water came out the end.
I was used to hooking for water services between 40 and 80 feet, where the water would just shoot out the end of the pipe like a fire hose.
The 350 foot line was running at 72 PSI and there wasn't much there at the end. Friction does take it's toll.

That's the last time I ever even considered using 1" for that distance.
The house next door, years later when that was replaced, we went with 1.5" PVC.

Thank you all. Trenching was the hardest part, not calculating proper pipe size as I said earlier.
