Sizing a Well Pump?
Building a Pretty Good House in NH. Well was just drilled and will have water pressure at 30 gallons/ minute @300 feet.
Well contractor wants to use a 1/2 HP pump and says it will use 5-6 amps. I asked about opting for a 1/3 HP pump (after reading Q&A here on GBA) and thought that was silly.
Will this constitute a major drag on electricity consumption? He said it will cost me $20 a month to operate. (17 cents a watt here in NH).
Should I push for the 1/3 horsepower pump? Or is a 1/2 hp okay? (Will it really be that expensive per month?)
