@VikingWays @sickburnbro Couple of ways, either shut all your power off except for the pump and look at the meter while it's running, or a bit more accurately with one of those "measurement socket things" that you plug into before going into the actual outlet.

I thought you might know what kinda pump you got there, but I can run with an estimate. Internet says 2,500 W for a pump that does 2500 gallons an hour.
Does that sound about right for yours?
