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).

Maximum Head Lift is the total height from the source of the water to the destination or drainage point. This provides the power to move water over a distance.

10.33 m

The pump at ground level acts as the source of vacuum and has a theoretical lifting capability of about 30 feet (It would lift 34 feet if it could create a perfect vacuum). In practice, 25 feet is all you should design a centrifugal or jet pump to lift in order to have adequate capacity left for water usage.

Water is pumped from a well by creating a partial vacuum above the water by the pump. The amount of vacuum, in inches of mercury, is equal to the weight of the column of water from the water table to the surface. Therefore, a total vacuum could only pump water from a depth of just under 34 feet or 10.3 meters.

10 to 20 feet

The average cost to replace a well pump is $1,675, or between $925 and $2,481, according to more than 600 surveyed homeowners. Shallow pumps cost around $1,000 to install, while deep-well projects cost roughly $2,000. Most well pump units retail for between $100 and $1,200.

100 to 800 feet

This is an over-simplification which does not account for peak demands, but it demonstrates that a well that reliably produces 3 GPM is adequate to meet the daily needs of an average 2-person household.

5 gpm

All in all, with all steps considered, it will typically take between 1 and 2 weeks to have a new well completely up and running. Of course, depending on several factors, it could take shorter or longer than this.

A well that yields only 1 GPM of water can still produce 1,440 gallons of water in day. However, water use in a home or farm does not occur evenly during the day. A 1-GPM well could only provide 120 gallons of water during this peak demand period, far short of what would be needed.

Well Deepening: Reentering an existing well and drilling to a deeper reservoir. Well deepening is re-drilling into an already existing well in order to find a deeper more productive reservoir. Sometimes a previously unproductive well can be deepened in order to reach a location with higher flow and temperature.

Most people don’t know all of this information, but it can be figured out by consulting with a water system professional. The Water Well Board suggests that the minimum water supply capacity for use inside a home should be at least 600 gallons within a two-hour period, or about 5 gallons per minute for 2 hours.

A standard 6-inch diameter drilled well can store 1½ gallons of water per foot of well depth. Alternatively, the New Hampshire Water Well Association recommends a flow rate of 4 gpm for a period of four hours as an optimum water supply capacity for a private domestic supply.

50 GPM is excellent.

Read on to learn four ways to increase your home water pressure when your home is connected to a water well.

1. Adjust Your Pressure Tank Settings.
2. Consider a Pump with a Higher Flow Capacity.
3. Upgrade to a Constant Pressure System.
4. Install a Water Pressure Booster Pump.

When you draw water, the level will drop some, but maybe not much. 10 GPM is probably a good nominal size for you, although 7 is good for many. A 1/2 HP 10 GPM may be best if your water level is 75 ft or closer.

If you aren’t trying to a whole lot with it 10gpm would be enough, especially if you use drip irrigation in the garden and/or orchard. We have an 8gpm well with a good recovery rate and are managing ok without any holding tanks.

How Many Gallons Per Minute Do You Need for Your Home? This is a loaded question, that really comes down to preference and the number of individuals that are in the home. The average household needs 100 to 120 gallons per person per day, and a flow rate of about 6 to 12 gallons per minute.

The formula for determining the flow rate is: gallons drawn down (that were measured above), divided by the seconds required for recovery, then multiplied by 60: (Gallons / Seconds) x 60 = Gallons per Minute (GPM) flow rate..

The 1.5 gpm figure should be your recovery rate. You have a 200ft well with water standing in it. How far from the top does the water come to? With a 6 inch typical well pipe you will have about 1.5 gallons of storage per foot of pipe.

Whenever it is warm out, there is a chance of your private well running dry. Most wells flow without problem through warmer months, but in areas of drought and a low level of groundwater there is a chance for them to run dry. Read on to learn about the signs of a dry well and what can be done to fix one.

There are several solutions for this:

1. Use a float switch or water level sensor down the well that turns off the pump when the water level gets low.
2. Install a Pumptec pump-protection box.
3. Install a cycle timer that only allows the pump to run a set number of minutes every hour or half-hour.
