Cost to run

How much does a well pump cost to run?

A well pump bills you per gallon of household water: every shower, laundry load, and sprinkler zone triggers motor runtime. Depth of the well and pressure-tank health set the efficiency.

Every gallon has a wattage price

The pump lifts water from depth and pressurizes the tank, so consumption tracks household gallons plus irrigation. Deeper wells demand bigger motors working longer per gallon, which the deep-well scenario reflects.

The pressure tank is the efficiency organ

A healthy tank lets the pump fill a reserve and rest; a waterlogged tank forces a start for every faucet touch. Frequent short starts draw surge current and wear the motor — the same pathology sump pits suffer from tight float switches.

Irrigation flips the arithmetic

Sprinkler systems can pass more water in a summer month than the household itself, doubling or tripling pump hours. Constant-pressure variable-speed pumps smooth this load but follow different consumption curves than the fixed-speed model here.

Frequently asked questions

Why did my well pump cost spike in summer?

Irrigation gallons dominate summer pumping. A modest sprinkler schedule can exceed all indoor water use combined, exactly as the heavy-use scenario models.

How do I know if my pump is short cycling?

Listen for starts every time a tap opens, or watch the pressure gauge bounce between narrow limits. A professional can check tank precharge; this page prices electricity, not diagnosis.

Do deeper wells always cost more to pump from?

Lifting water farther takes proportionally more energy per gallon, so depth raises both the required motor size and the cost per gallon delivered.
