I have a big elevation drop from one side of my house to the other. I must choose one of these sides as a take off for hose spigot-to-PEX which I'm going to lay under ground toward my garden about 600 linear feet away.
If I take off the North side, it will have to go uphill the whole way to the top of the garden area and then downhill as it heads into the garden area. If I take off the South side, it will go downhill most of the way and then uphill into the garden from the south side, all the way to the future garden spigots.
I'm worried about the water, which is of course under pressure like a normal hose would be, would perform poorly if I chose the South route and after it going uphill the whole way. But maybe being under pressure it'll be fine no matter what? The South route is preferable for other reasons. But it would be a disaster if I put it in and it didn't work.
Thoughts? Does it matter which way you route from the house to a garden for water flow?
I decided to test it by running a garden hose the entire length along both paths (yes... 600 feet of chained hoses!)... the pressure at the end felt the same either way. So it sounds like the route doesn't matter. It was definitely diminished (I could stop the flow with my thumb), but usable I think (for drip line), and that's with 5/8" with various leaks along the way. The PEX I'll be laying in the larger 3/4" and of course won't have any leaks. Hopefully, that will be enough to power the drip lines?
