We are building a new house and have already drilled the well (hit water @ 180', drilled down to 205', water rose to about 40', & is estimated to provide about 16-18 gal/min). Below are the quotes I got from the local pump dealer/installer last night:
Standard system - $1925 - ¾ hp 10gal/min pump, 20 gal pressure tank, 1 yr warranty on everything (I forgot all the details, but it was a basic system that didn't have a lot of bells and whistles.)
Premium system - $2250 – upgraded ¾ hp 10gal/min pump, 20 gal pressure tank, 5 yr warranty on everything (1yr on labor), all stainless, brass, or bronze hardware, extra foot valve half way down, conduit for wire(house to well).
Pressure tank upgrades: 40 gal (+$185), 80 gal (+$220)
He also mentioned a constant pressure system, but didn't have the exact figures for it, but said it would probably be around $3000. It would include all the hardware the premium system has, but would use a Goulds pump and the Franklin motor & controller.
Is it worth it to upgrade to the constant pressure system from the premium system? I'll need to make a decision by Friday. We will be starting our brick work in 2-3 weeks so I have to get this installed. If I went with the premium system, is the ¾ hp 10gal/min pump big enough?
