A typical ¾–1 HP well pump draws about 1,000–1,500 watts and runs whenever the pressure tank calls for water. A pump that short-cycles or runs constantly usually signals a leak or waterlogged tank — and shows up as a mystery bill increase.

How to lower the cost
- Set water heaters to 120°F and fix dripping hot taps quickly — a drip is a slow leak of paid heat.
- Shorter showers and low-flow heads cut costs directly; hot water is usually a top-three energy use.
- Timers and covers transform pool, spa, and tank costs — stored heat and off-hours running are much cheaper.
