I have a 75ft well that is not in use but would like to use it to water the garden and, if needed, fill the main well in case of draught. Considering both the main well and garden are a good 200ft away would you have a suggestion on what pump to use? Additionally, my plan is to just use an extension cord, plug and run as needed, I guess i could install a switch if I'm feeling snazzy but I rarely feel snazzy.
