Pump strength is measured by the amount of water that is can push out of a 1 ½ inch PVC discharge line. Most pumps have a flow chart indicating the Gallons Per Minute (GPM) with the feet of discharge line. The length or height of discharge line is called head. 10 feet is the average height of discharge line.

The key to sizing a submersible well pump is to calculate the gallons per minute of water required during peak periods. Smith recommends sizing a submersible well pump based on fixture count, which involves counting the fixtures and faucets in a home.

10 to 20 feet
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.

The amount pumped out of the well and the amount going into the well from the surrounding groundwater need to balance, or the well will “run dry.” But, when too many wells tap into the same groundwater supply, a long drought occurs, or more water is used around the home than the well can supply, there can be problems.

A water well pump is a device used to draw water up from a well for delivery to a home or other structure. Pumps are necessary in sunk wells because the water cannot rise to the surface on its own.

The type of pump used generally has to do with the amount of water needed, the climate, and the contractor’s preference. Water well pumps of the submersible type are used in a majority of American homes. These pumps are long cylinders, about 2-4 feet in length and 3-5 inches in diameter.
