Can a shallow well pump be used for a tiny home?

Choosing the Right Pump for Your Tiny Home

When selecting a shallow well pump for your tiny home, consider the well depth and water table level. A typical shallow well pump can handle wells up to 25 feet deep, but some models can reach depths of up to 50 feet. The ideal pump size will depend on your daily water usage, which is typically around 10-20 gallons per person per day. For a tiny home with 2-3 occupants, a 1-2 horsepower pump with a flow rate of 5-10 gallons per minute (GPM) is usually sufficient.

Well Depth and Pump Selection

To determine the correct pump size, calculate the well’s yield by multiplying the static water level (SWL) by the well’s diameter. For example, if the SWL is 20 feet and the well diameter is 6 inches, the yield is approximately 24 gallons per minute. Choose a pump that can handle this yield and also consider the pump’s efficiency, which is typically measured in gallons per minute per horsepower (GPM/HP). A high-efficiency pump will save energy and reduce your water bill.

Installation and Maintenance

Proper installation and maintenance are crucial for a shallow well pump to function efficiently and prolong its lifespan. Ensure the pump is installed at the correct depth, and the well casing is properly sealed to prevent contamination. Regularly inspect the pump, check the water level, and perform routine maintenance tasks, such as cleaning the well screen and replacing the pump’s impeller, to prevent clogging and ensure optimal performance.
