hi all, just trying to get some inputs with what I need on here. I live in a rural area and currently have a 2hp well pump and ~89 gallon pressure tank. My well is pumping around 2 gpm at a depth of 900 feet. The well drys up after about 45 minutes of continuous pumping. A contractor recommended that i get 2500 gallon cistern, booster pump, pumptec plus and labor for total cost of $4000. is this quote reasonable?
