The Shurflo pumps come with built in pressure switch. I'm not aware of cheaper big pumps having that.
I like the posters innovative water supply and wanted to add a idea or two.
I, too, have property on a mountain top with no well OR electricity. I had three well driller all estimate that a well would be over 900' deep and need casing. $$$
The power company will not run elect up my mile long road unless I "build a year round permanent residence".
The property is an unattended mainly forested 70 acre farmette that I plant mini crops for the deer....haven't killed one in 10 years.
Anyway, I digress, sorry. I have three of the tanks that the poster shows. I fill them in town, 275X8= 2200lbs and tow them back up my mountain. I have a generator and AC pump to transfer to an empty tank (can't lift them). I use a water hose to pipe the tanked water to a ext. fawcet. I plumbed the building thinking that I would eventually have a well. The water enters the building and goes to a DC MARINE 12V pump that DOES cut off with adequate pressure. The pump puts out 3.3GPM. After the pump (probably should be BEFORE) I have a large whole house water filter, then the water splits going to a propane wall mounted water heater and/or on for cold water to a SHOWER and DEEP SINK.
I have 4 SOLAR panels and 4 marine batteries to supply the DC for everything; lights, water, inverters for light AC. I rarely run the noisy gas generator.
This makes my building inhabitable for a couple of weeks of serene, QUIET, peaceful escape.
