I'm interested in developing a spring on my property, I've seen some tutorials on building spring boxes, and I was wondering what the best material and diameter is for running a pipe from the spring to where I want to user the water, Something non - toxic.
It may be a few hundred feet to the spring ... I have to find the actual spring head, was thinking of putting a shutoff at the top with a purge valve, so I could blow out the pipe with compressed air for the winter
Black poly is the normal thing. Read the label carefully, there is stuff that isn't for drinking water, there are also 2 pressure grades. You likely won't need much pressure, but it has to do with how durable the pipe is.... Sure is better if you burry it some, here we go 5 feet for freeze protection, sounds like you aren't here tho!
There is a blue plastic pipe now that is thicker walled, much more durable, that most folk are using for water lines now. Good tough stuff. I would use that, but I hate having re occurring problems later on with leaks and all.
The farther water has to travel in a hose, the more resistance it has.
So size of the hose depends on the pressure it is getting (gravity feed?) and the distance it has to go.
At least 3/4 inch, and a gravity feed 500 foot setup you might want 1.5 to 2 inch depending on what all you are doing with the water.
