how to get water pressure uphill approx 1000 ft?

There are a few things you can check. First is if the pump is a surface ( jet) pump you have to be sure it is primed. Next would be if the pressure tank is swamped with water you would experience a lack of pressure that far away. You would shut the pump off, drain the tank down of water, and then open the valve back up so the pump creates a cushion of air in the tank pressurizing the line. The last thing to do is see how the pressure is right at the well house. If you are getting good pressure there then you can eliminate two things: the well has gone dry or the pump/motor is shot. If you have a submersible ( in the well) pump, hope that the tank will re-pressurize after draining it and all is back to normal. If none of these work you will have to call a plumber.

is there a pressure tank at the cabin? it looks something like a water heater. there should be a pressure Gauge attached to it. you might need to add air to the pressure tank. there should be a fitting

on the tank to add air it would look like the same thing on a car tire or a bicycle tire. it should say on the tank what the pressure needs to be. 1000 ft. is a long way. you might need to install another water pump mid way in the water line. have a well pump guy come out and look at it would be the best thing.

you could follow the water line from the pump to the cabin and see if there are any wet spots, that would be a leak.

I don't think you mean 1000 feet uphill. I think you mean uphill and 1000 feet horizontally. Water pressure is a half pound per foot of rise. A 1000 foot rise would mean 500 PSI water pressure at the bottom, which is a lot. It sounds to me like you just need a mechanic to come and fix your system.

verify the voltage first. some pumps can cope with the two a hundred and ten volts or 240 volts reckoning on your pumps call plate it in straight forward terms differs to the way it truly is connected (leads). in the journey that your pump can not cope with a hundred and ten volts then it is going to trip your thermal overload relay if put in. in the journey that your grant voltage is decrease than your desired, the present will upward push and could trip your pump motor. If those have been checked and have been ok then have your pump pulled out. in all likelihood reason could be a blocked or broken impellers. Leaks on your pipeline could be a reason too. good success in you troubleshooting.
