I was helped on this site sizing pump for low -producing well that is 358’ deep. I ordered 3/4 hp 5 gpm Flowise submersible and #12 gauge wire. However, the supplier substituted a 1 hp 5 gpm pump without telling me. The 1 hp pump is rated maximum for 400’ for #12 wire and I’m at about 420’ from sub-panel. I’m way out in the country ready to install but wondering if I should hold off and get correct pump. Also, I’m pumping into storage tank and I will have only 25 gallons of water above pump in casing. Is this 1 hp pump too big? Thanks!
