 Exterior water pipe type and size recommendation
Author: r1013 (AL)

I put an RV on rural land to stay in on my off days while I build a house. The power company ran power which is set up. A well was dug/setup last week with a 1" brass female fitting coming from the pump/tank connections. I need to get water to my RV (about 250' away down hill at approx. 10% grade). I also need to get water to the house site another approx. 250' away in the other direction up hill at approx. 20% grade.

I bought a couple of no lead frostless Yard Hydrants with 3/4 inch connections. One for the RV and one for the house site. Our coldest temps are mid 20's maybe a month or two a year dropping occasionally into the teens 1-7 days a year. I live in middle Alabama where the frost line is 6". Code says bury the line 6" below frost line which makes it 12" deep. This doesn't require inspection where I'm building but I want things done right.

When the house is done, the plan would be to come off the line close to the Yard Hydrant by the house site and go over to the house, maybe another 20'. There is also a meter that was dropped prior to me buying the land 800' down (23% grade) hill, but I wanted a well.

I thought about running a line to the meter as a backup but that's a lot of digging. The pump installer said to use 1" pipe coming off the wells 1" female connection and run it to the house. It seems like 1.25" would be better but would the 1" outlet at the well effect it negatively? A plumber I spoke with a few years ago said to run 2" pipe from the meter to the house.

My questions:
What TYPE and SIZE pipe should I run from the well to the RV and House site? If now or later I decide to trench to the water meter, what TYPE and SIZE pipe should I use? Every article I have read says to use something else. Any suggestions?

google "Hazen-Williams friction loss" then consult an architect



my personal GUESS would be 1-1/2




as for material: smooth, flexible, CONTINUOUS RUN, properly backfilled with 6" SAND top and bottom (PEX comes to mind)
