I just ran a 650 foot 1-1/4 inch pipe from my water source, up a hill, where the rise is about 35 ft. I expected some water pressure loss, but I have much more loss than I was expecting. This water line will eventually run into a residential home.
I don't have the water pressure exact numbers, but at the bottom of the hill the water company says they are about at 55-60psi. At the top of the hill, I can place my hand over the hose and stop the water. It barely trickles out of a hose. I put a pressure reader on it, and it didn't move. I'm not sure if there's 0-1 psi, or if what I bought is broke, but either way it's very small.
Possible solutions and their issues
- I can get a more direct pipe to make it shorter. I could go from 650 ft to about 450 ft, but with how low the pressure is now, I don't know how much that would help.
- I've looked into getting a pump at the bottom of the hill, but at the moment, I can't get power down there.
- I know there are systems to pressurize the water once it's in the house lines, but that doesn't help now.
- We do have power at the top of the hill, so I could put a pump up here, to pump up the hill, but I've read that's not a great idea past 20ft in elevation.
- I talked to the water authority and they said most people in the area that have this issue just put a tank up the hill. I'm not sure if he means a separate tank so the water comes from the same level as the house, or if he meant something else.
What are some other options I'm not thinking of?
