 New construction main water line planning
Author: fearnow (IN)

Hi all, new here. I'm planning the main water supply. My main question is, sizing diameter of supply. I'm planning to use PE due to the length of the run and cost. The first phase of construction is the "pole barn". In a few years will be the house. But I may later extend and do some "pasture paddock" lines for animals. So this is why I'm in the planning, and want to make sure I size it right. IIRC, the main supply (city) is 4".

Below is shared png photo aerial view. From "Start" to "Mid" is ~125', and "Start" to "Finish" is ~250'. It will probably have a drive that would go over in between the Barn and the House. Pink is approx outdoor hydrants.

Also. The barn will have a commercial kitchen and full bath. House to have 4 bedrooms and 2 1/2- 3 1/2 bath.

TIA

i would run 1 1/2 inch to the house and feed the barn from the house with 1 inch.

The hydrants should be home run supplied vs. branch as they will need some form of back flow protection.

Piping size is determined by length of run, existing water pressure and number of fixture units to be installed. Good luck.
