The well pump should be able to push more water than the average household use requires, ideally supporting 5 gallons per minute to maintain steady flow and water pressure throughout the house.

Factor	Consideration
Pump Depth	Determines the type of pump (shallow or deep well)
System Pressure	Influences the tank size needed to maintain pressure
Pump Rating (GPM)	Ensures sufficient water flow to meet household needs

For more details on selecting the right well pump for your home, consider the water table measurements. The depth of your water table will determine which kind of pump you need and the best place to put it (Home Depot). For instance, when replacing a shallow well pump, it’s often best to replace your old model with a new model of the same horsepower. However, you may need a pump with more horsepower if you have added new appliances or fixtures.

Understanding these factors can help homeowners make informed decisions about their well pump replacement, ensuring a reliable and efficient water supply.
