I got a quote for my well to be drilled and they gave me a price list for a 1/2hp, 3/4hp and 1h/p pump. I thought that 1/2hp was the standard, but I'm considering 3/4hp. We have a 3800 sq.ft. house and want to install a hydrant near the garden, and I HATE low pressure in the shower. Which size would be recommended?

The size of a pump is dictated by the total dynamic head and gpm requirements of the system it will serve. The static water level in the well is involved. Also the type of well, screened or rock bore, has to be taken into account which determines the depth the pump will be set at. Then there's the pumping depth and recovery rate and then the presure you want the pump to operate at. Only after all that is known do you look for the hp needed to do the job. The reason is due tothere being two distinct parts to a pump; the wet end (pump) and the motor. Only the motor is rated in hp. BTW, location elevation above sea level is also a factor.

So with no more info than you've provided, it's anyone's guess but... your well driller/pump guy is 'selling' you if he hasn't shown you the math as to how each pump he's suggesting would fit your needs.
