Little Giant versus J-Series subemersible water well pumps

[LLigetfa]

Why not do away with a tank altogether...

Even the VFD pumps have a small tank. Just because the CSV can work with a small tank doesn't mean you need to change out to a smaller one. Any small draw would start/stop the pump... any draw... leaky toilet flapper, ice maker, humidifier, RO filter.

As for energy consumed, it varies by pump maker as to how the impellers are fixed or floating, but a pump moving less water uses less electricity up to a point. As I said, standard practice is to match your sprinkler system to the pump wherever possible.
