What is the cost to replace a 1.5 hp pump I was told when well installed: Pump is 275' down and well is 575' deep. I am trying to plan for when the time happens it is 12 years old and is a Red Jacket pump. I am in NW Florida. Is it possible to do yourself or is major equipment required. I know it depends on brands etc but I am trying to figure a cost. Do you have to replace the tank and wiring also? What is a upper brand of pump with a good long service life. Also are the constant pressure things worth having for the cost? Do they cause the pump to run constant when a faucet is on or what? I appreciate any and all inputs. I would rather be proactive.
