Bars are reported WEF from each pump's own certified record. Colour is the speed class. The outlined bar is this pump; the others are the nearest-sized certified in-ground pumps in the detailed set, within 0.2 hydraulic horsepower.
What it draws to move water
This record publishes one measured operating point, so there is no second point to draw a line between. A variable-speed pump is tested at its speeds, and the figures in the table below are the whole of what the test reports.

Rated motor horsepower and rated hydraulic horsepower are different quantities. Hydraulic horsepower is the water power the pump actually produced in the test; motor horsepower is a nameplate rating that includes the motor's own losses and any service factor. Two pumps sold as "1.5 hp" can differ by more than a factor of two in hydraulic horsepower, which is why this site sizes and compares on hhp and flow.
What it costs to run
The scenario below is this site's editorial default, not a figure from the certified record: 10 hours a day at the low-speed measured point, at 18.31¢/kWh — the u.s. average retail price of electricity to residential customers for July 2026. Change any of it in the cost calculator, which opens with this record's own figures already in the fields: 120.1 W at the low-speed point. Nothing on this page is an estimate, and neither is anything the calculator starts from — the hours, the electricity price and the season length are the only editorial numbers, and all three are yours to change.
| Operating point | Watts | Hours/day | kWh/day | Cost/day |
|---|---|---|---|---|
| Low-speed measured point | 120.1 | 10 | 1.201 | $0.22 |
| Total | — | 24 | 1.201 | $0.22 |
These are arithmetic on the certified watts, nothing more. A pump installed in your plumbing sits on a different system curve than the test rig, so its real draw at a given speed will differ. Measuring at the panel or with a clamp meter is the only way to know your own number.

Next: work out whether this pump's flow turns your pool over often enough with the turnover calculator, prefilled with its 31.1 gpm low-speed measured flow; compare it against another certified pump at one electricity price in the cost calculator's side-by-side view; see the other Waterco records held in detail; read what the weighted energy factor does and does not tell you; or check the methodology for every source and assumption behind this page.
