Common questions
Does nameplate wattage equal measured use?
Not always. A plug-in energy meter gives a better average for compatible pumps.
How does Sump pump runtime energy cost calculate the result?
Cost = watts/1,000 × minutes/60 × cycles/day × days × tariff.
What should I verify before using Sump pump runtime energy cost?
