Which Well Pump

[dm0978]

I have a submersible well pump feeding a 1500 underground storage tank. I now want to install a pump which will draw from the storage tank and feed an undergound sprinkler system. Should I buy a conventional jet pump with a pressure switch and pressure tank, or an electronically controlled pump, which requires no pressure switch or tank?

I'd buy a submersible pump, install it in the tank then install a Cycle Stop Valves "Pside-kick" kit. The Pside-kick comes with a small tank, cycle stop valve, a pressure switch and everything you need. http://www.cyclestopvalves.com/st-viewcat.php?cid=26.

Stay away from VFD pumps, they are expensive and troublesome.

Conventional jet pumps are not too shabby in this application. Their 'sweet spot' is right in the operating window of common lawn sprinkler heads. A baby pressure tank combines with the pressure switch already on the jet pump to give you a complete supply for a sprinkler system.

I've looked at the Pside-kick. I think I understand it, but I'm not sure. How is it different than a pressure tank, pressure switch, and water pressure regulator combination.

Jet pumps have a more pronounced curve and as a result the loops are easier to tune to match the curve. A sub would be more energy efficient if properly matched but they may be harder to match due to their curve.

A CSV would allow for a wider range of GPM and save having to tune the loops. When used with a CSV, a sub that does not float each impeller would likely draw less power than one that does.
