I need to supply my house from a cistern 20ft from house and 2ft vertically on a slope. Supplying 1 1/2 bath frequently,and an additional 2 when occasionally family guests are in. The lift from tank base to highest shower head is about 27ft.
Planning on using multistage centrifugal pump, either a submersible Ebara Multigo 40/06 with max head 128ft and 22 gall/min, or an ESPA Aspri 15/3 with max head 110ft and 17.4 gall/min, or the 15/4 with head =147ft and 17.4 gall/min.
Controlled by either by;
1. Automatic electronics pressure/flow controller that turns pump on/off according to demand, or
2. Pressure tank system with Cycle Stop Valve.
Cant figure the difference between 1 & 2, are they not doing the same thing. Think I am missing something.
Efficiency is my major concern. Which setup is best?
Thanks in advance.
