Glad you tested your well. My dads was a 3/4 hp pump we think, it pumps 12gpm from 200 ft. If we are correct then I guess yours is a 1/2 hp and you are fine. Great setup, you are lucky to have it.
I just asked DH - he remembers we had a 6.5 watt gen, ran the well on 220. It didn’t wear out the gen since it got uses now and then. He now has a potential solar set up with altnerate pump if needed. We still run the well pump once a week or so.
