I'm building a water system for a rural cottage/cabin to augment the existing generator powered pump. I want to add a 1,000 litre (250 US-Gal) cistern and a solar powered pump to give us a water supply and some pressure when we're running off battery.
The general layout is shown in the diagram. The pump itself is in the attached photo.
I've added a bypass to the pump so we'd still get low-pressure water from the cistern, even if there's no bettery power for the pump.
The water in the lake is not potable, so this is just for showers, dishes and washing.
Have others set up this sort of thing? Any pointers?
