My barn area is on well water at about 30psi. The hose bib where water comes comes in has great pressure. I ran pex up and over to the other side of the barn for a couple more hose bibs. Those obviously have lower pressure. It hasn’t been an issue until trying to add a mist irrigation system for new garden boxes. I can’t go underground all the way as there is concrete in between. Anyone have a solution? Pump? Regulator?

You have a pressure tank that you can turn up? I don’t see why going overhead would change the equation. Are you certain it’s not a volume problem?

Do you think the lift with the pump to go up and over may have an issue? Can you just stay at the same height as the other bib and go the perimeter of the wall to the other side? pex is cheap enough but keep it out of the sunlight. Tank may be a solution. Not a plumber

I do have a tank that can be adjusted but it’s coming out of there just fine. The line from tank to the first spigot is 50-60 feet and runs under ground. From there I go up and over. There’s not really an option to stay low. Going to add a lift station just north of the first spigot and see how that goes. Will report back.

most all well pumps i have seen set the pressure regulators at 60-70 psi so theres that

turn your pressure up where it is supposed to be set

No matter how high you go up as long as you come down to the same level the pressure should not change other than the losses in the length of the pipe which you would have even if you ran under ground. The weight of the water hurts you on the way up, but helps you on the way back down. So no matter the route of the pipe, pressure is equal at equal elevation.

Even city water is 40-60 so if you wanted to go 50 you would be the pressure of an average home.
