In general, most submersible pumps can pump about 150 feet or so from a well. However, this will depend on the size and depth of your well. If you have a large well, then you will be able to pump water from farther away. On the other hand, if you have a small well, you will not pump as much water from it.
What is considered good gallons per minute for a well?
The Water Well Board suggests that a minimum water supply capacity for domestic internal household use should be at least 600 gallons of water within a two-hour period once each day. This is equivalent to a flow rate of 5 gallons per minute (gpm) for two hours.
Is 100 feet a deep well?
The average well depth for private homes is between 100 to 800 feet [2]. You may need a deeper or shallower well if your area has different geology than another region of the country.
Is 20 gallons per minute a good well?
You could have a great well water flow rate - say 20 gallons per minute - but if it the water will only run at that rate for five minutes before you run out, the well has a very poor water quantity (5 minutes x 20 gpm = 100 gallons of water) and it's not a satisfactory well.
At what depth is a well considered a deep well?
So, when is a well considered “deep”? The most important aspect of depth is not the well's absolute depth–30 or 40 or 100 feet–but rather how far its casing extends below the water table.

Pumps should never be set directly at the bottom of a well. It is usually best to place the pump 10 to 20 feet up from the bottom of the well.
How long do submersible well pumps last?
The main factors affecting the longevity of your submersible well pump are: the water quality, the quality of pump selected, the competency of the installation and the quality of the power provided to the well pump motor. Industry averages show that submersible well pumps last, on average, about 7 years.
How many hours can submersible pump run continuously?
Generally, sump pumps can run for six to 24 hours continuously, depending on how heavy the rainfall is and the quality of your pump. The aftermath of torrential rains or even flooding puts a higher demand on your sump pump to keep your home's low areas dry.
What are the limitations of submersible pump?
There are a few disadvantages with submersible pumps, and two have to do with the seal. The seals can become corroded with time. When that happens, water seeps into the motor, rendering it useless until it is repaired. Also, that seal makes the submersible pump a bit difficult to get into for repairs.
What is the maximum depth for a shallow well pump?
A shallow well pump can only draw water from a maximum depth of about 20', and for these shallow water table depths, 1-1/4” diameter well pipe is sufficient. A deep-well pump installation is necessary if the water table is deeper than about 20'.

How does a jet pump work?
A jet pump draws water from the well into your pressure tank. It draws water from either one, or two lines coming from the well.

What is a well pump?
The pump usually refers to both the pump itself and an electric motor, which together make up the pumping unit. The pump may be one of several types: shallow or deep well jet, submersible or reciprocating. Along with the pump, a pressure tank is used to build up a reserve supply of water during times of high demand so the pump starts and stops less often. Less frequent cycling can prolong the life of a well pump.
How many people use water wells?

How does a well pump work?
Census Bureau indicates that over 15 million households in the US, for example, depend on privately owned wells for water. The typical well water system works by lifting water from a source located underground and delivering it to a tank. From there the water is stored and pressurized until it’s needed. The majority of well water pumps are electric-powered and use suction for drawing the vital liquid through pipes.

What is the design point of a submersible well pump?
As we just mentioned, the design point for a submersible well pump is the combination of how much pressure the pump needs to provide and the quantity of water the pump is expected to supply at that pressure.
