My 1865 home has a mortar and stone tank underground. It's about 6 feet in diameter after a narrow brick opening, and 16 feet deep. The last time I checked there was 8 feet of water in it. There are some terra cotta pipes that lead to it, and similar pipes near gutters, I assume this is how it gets water but I need to test that. I also assume that this wasn't a septic tank at some point...
Anyway, I figured this would be a great source with which to water the lawn. We are on a slope, and the high side of the property is 10 or so feet higher than the well, so I would need something that can pump 26+ feet and power a sprinkler, right?
Here's where I get lost. Do the pumps have to be installed indoors? Is in my detached garage fine or do they also have to be protected from cold? What PSI/HP/etc do I need? Some pumps say they self prime, some don't, is priming a pump difficult? Is there anything else I should know?
