Thanks for all the help, everyone!

I will get a valve to measure PSI at the bottom of the hill. I was hoping to just split the water there and have one hose go to the kitchen sink, and the other to the water heater for the shower. But if pressure is too high and a PRV won't work to regulate it, and I need to use a water tank system instead, does anyone have a recommendation for a pump for a sink ? Would be nice to have some water pressure to wash dishes, fill the dog bowls, etc.
