What size water well pump do I need?

Herein, how deep can a 1/2 HP well pump go?

A two-line jet pump can typically raise water from depths of 30-feet to 80-feet, and at water delivery rates of 4 gpm (gallons per minute) (for a 1/2 hp 2-line jet pump serving an 80 foot deep well) to 16 gpm (for a 1 hp 2-line jet pump serving a 30 foot deep well).

Secondly, what size well pump do I need for irrigation? To determine the correct sprinkler pump size, you'll first need to figure out how many sprinkler heads you have along with their GPM (gallons-per-minute) and PSI (pounds-per-square-inch) requirements. All sprinkler heads are rated at a specific GPM and PSI.

Correspondingly, how do you size a water pump?

Quick Formula

1. Water horsepower = minimum power required to run water pump.
2. TDH = Total Dynamic Head = Vertical distance liquid travels (in feet) + friction loss from pipe.
3. Q = flow rate of liquid in gallons per minute.
4. SG = specific gravity of liquid (this equals 1 if you are pumping water)
5. Water horsepower =

What size pressure tank do I need for my well?

Old Pressure Tank Sizing Method. In the past, pressure tanks were sized to store at least 1 or 2 gallons of water for every gallon per minute the pump can produce. A 10 GPM pump needed a pressure tank that holds 10 or 20 gallons. A 20 GPM pump needs a tank with 20 to 40 gallons of storage.
