150 ga tank and float

There are a bunch of plastic tank manuf. on the web. Tons .What would you recommend for a 130-150 ga plastic tank for potable people water
with a quality float switch. Square would be better.The tank would receive low pressure water intermittently from about 100 ft away. It has to have an outlet at the bottom.I would want the float switch to short the DC pump at about 90% capacity. thanks

Don't know about the Flotec pumps, but if you don't have a hill nearby, the next simplest is to have a pressure tank (water tank with rubber internal air bladder to allow pressurizing) and a pressure pump (positive displacement diagphram, RV pump etc.) with a pressure shutoff switch.
If you open the tap pressure drops as water is dispensed. At some point the pump comes on and refills the pressure tank. The back valve you mention is to keep the pressure in the tank (just a spring loaded check valve).
Some 12 V RV style pumps have built in pressure reservoirs and pressure switches and even have their own check valves built in. I don't know if they can deliver the same flow rates as a 1/2 hp pump which you might have to setup with your own tank and valves.
