Looking for suggestions and input as to what I may have missed.. New construction. I have a 12 foot deep 5 foot diameter spring fed cistern. I have used this source in a different way for years.. House is appx 200 feet from house on a slope with a head of about 40 feet to basement pressure tank 100 gallons in size . House has basement plus 2 stories. My plan is to have a small pump house next to spring cistern containing pump, and aux 120v source for lights plus an outlet. Pump I had in mind is a Flotec FP4312 ½ hp 240v.The line from spring cistern to pump would be 1â€. I have run an 1 1/14 200psi line to a 1000 gallon storage cistern next to house buried to keep from freezing. The actual house pump would be in the basement feeding the pressure tank. I had planned to use the same pump at spring cistern and house . Better suggestions??? The pump has an 1†output line and input . Would this be a problem going to 1.25 line from spring to house cistern?? Main reason for the HD line is in the future I may want to have an actual deep well near the spring cistern. Or, should I run a 1†line as well. Electrical would be burial 10/3 two runs as I may want added electrical down by the spring. Now for the controls, my thinking is to use a tethered float in spring to keep pump from running dry. Also there needs to be a float in the House cistern to tell lower pump to refill the upper house cistern. This is an area I really need help. Sorry for the novel , just trying to give all the info I can. Thanks for the help in advance…… Doug
