Finally got our place. The well and pump are 15 years old, well was rated at 62 gallons a minute by the drilling company, about 310 feet deep, pump is a 3 horsepower supposedly 18 gallon a minute pump down about 275 feet. There is also a submerged pressure tank in the well. 3 phase system.
I did not know about the pump until I started trying to run more than 3 sprinklers at a time, then the pump did an auto low pressure shutoff. Then I called the company and they told me how to manually reset the well controller and about the pump. So here's the questions: -why would they put only an 18 gallon a minute pump in a 62 gallon a minute well? the company told me at that pump's depth plus the pressure tank I should be getting about 25 gallons per minute but they will come check it out because it sounds like not even getting that currently -if the pump is going bad should/can I replace it with a more powerful pump, and if so how close to the 62 gallons a minute should I get? -any other thoughts? We have 10 acres and want to do some light farming and animal stuff, also bordering a few hundred acres of state land and might irrigate the edge of that to grow some stuff for game birds. _________________ If you vote for Biden you are voting to be murdered when he sends Beto to come take your "semi automatic assault weapon" (any semi auto).

I can't answer your questions, but my well feeds a reservoir that is elevated a bit on a hill. The reservoir actually has more than a day's worth of water in it so I can run the sprinklers at whatever rate, so long as my total water usage isn't more than the pump can refill in 24hr.
The pump is driven by water level in a simple way: on at a low level, off at a high level. In a power failure if I stop watering the lawn I can stretch my usage at least five days. Dunno if you have the option to eventually do something like that. The elevated reservoir also provides good water pressure even in a power outage. |

so well logs and well production are based on pumping air into the hole over 24 hrs with a big compressor not what the chosen pump parts will produce. Depth, parts used, clogged screens will all effect actual production
18 gal a minute is pretty rightous production, you can always spend more money on the parts to get more water. you can also set up a cistern system to handle peak use demand, this can be set up to pump at set intervals and when demand is low to fill a good size reservoir leaving a good reserve and less of a strain on the well itself and the equipment |

Typically pumps dont start to die, they just fail.
I would figure out if you have a bladder tank or just a pressure tank. If its a tank, they suck and need bled/drained. Get a bladder. See if the check valve is holding the water in the plumbing or if its letting the pipes drain back into the well when it shuts off. Existing plumbing in the well could have a small rusted pin hole making it take longer to build up to shut off pressure since a small amount of the water is waterfalling/leaking back into the well. Just because a well can produce a certain number, its not always in your best interest to run it to the limits. Have you priced out what it costs to drill a 300' well in your area? it will scare you. Dont kill yours. |

Your well's recovery rate will have more to do with the gallons per minute you can pump - if the well cannot refill at the rate of 62 gallons per minute, you cannot use that much water straight from the well.
Even a 6 inch well casing going down 300 feet only holds so much water. Your best bet is to have a large holding tank or reservoir of at least 1000 gallons in size you can slowly fill, and keep refilling over time as water is being used up. Don't forget to install a stock tank heater or something similar to keep the tank from freezing in winter. A check valve on the tank and a flow rate restrictor on the well line supplying the tank will make sure that you don't draw the well dry trying to use water that is not recovering at the rate you are drawing it out at. Your pump is probably rated for and drawing the maximum of what the well can sustain already. _________________ Give a man a fish, and he will eat for a day.

What’s the size of the line feeding the sprinklers. More volume = more water. Pressure is pressure, need larger pipe.
