New here, we plan to build a house and ran a 1” line approx 1600 feet - the elevation change is appox 100 yards uphill - at the bottom we have 150psi - there is no water at the top of hill - any suggestions on what we can do to fix this? Suggested PSI?

Thanks ..

Water loses 0.434 psi per foot of elevation.

150 psi of pressure should climb 346 ft. or 300 ft and have about 19 psi left over. Your pressure number may be high or your altitude rise may be low.

What kind of pipe?

You will probably need to put a booster pump part way up the hill. I don't have a pump recommendation, but there have been some discussions.

This chart goes up to 600 feet and doesn't take into account elevation gain.
1" is way undersized for what you're trying to do. The more distance you run that pipe, the more "friction loss" you get.
Whose decision was it to only run 1" ?

Curious, where in Florida did you find a 300 ft. elevation?

The highest point in the State (Britton Hill in the panhandle) is only 345 ft--we've been there, you have to hike about 8 feet uphill to get from the parking lot to the marker...

Hey, wait a minute.

This is awkward, but...
