How about a good sure flow bait pump. I would run on 12V.

Yep, a good RV water pump or similar 110v inline pump will do the trick.
If placing an inline pump, try to place it near the bottom of a vertical run of pipe. This will help keep the pump primed and prevent cavitation from
low supply flows. Most of the pumps have a pressure switch so when you shut the valve, the pump will stop. you can then turn off the pump and drain
the pressurized line on next use.

We have a jacuzzi pump with an on/off switch. I only turn it off when we are not getting water from the street to reduce usage. Oh and I turn it off
when we leave for more than a few days. However this makes watering our garden problematic for the waterer. Do you have a tenaca? I dont think this
would work without some kind of holding tank(be sure to put a cutoff foot in it, so the pump wont run dry.)

I've often thought of this but you obviously have more confidence in the ability of your plumbing to hold up to the increased pressure than I have.
Somehow I don't think they had any plans on the plumbing ever being subjected to anything more than the head pressure of a gravity flow system from
maybe a roof tank. I keep envisioning all these PVC couplings blowing apart inside my walls!

I have a friend who runs his entire house on a 12 volt Shurflo (DO Not Use the Variable speed) with a small pressure tank and a 12 volt system, but
I prefer the small pump and pressure tank. If you are concerned about the lines and pressure, you can adjust the pressure down to somewhere around 25
lbs which is very low. The only thing the pressure tank does is to act as a deposit of water pressure which lets you "withdraw small amounts" without
having to recharge the system everytime you take out a little.

The pressure tank also stops the water flow from pulsating.

Alan said "I keep envisioning all these PVC couplings blowing apart inside my walls" - PVC is pretty tough, especially at household-type pressures.
My own nightmare - personally witnessed from a seated position - was a cheap potmetal/cast metal valve exploding - you know, the kind they use under
sinks and toilets for switching off water lines.
I checked ALL the valves and found three others leaking! The disaster here is that if you are not present, the home pressure system will merrily spray
water all over your house until your 4000l cisterna runs dry, followed by your pump burning out.
Buy the best you can find - and if you are having a house built, keep a beady eye on the components!

Rob, the other solution is to always use a float switch on your tinaco or storage tank. This is a safety switch which keeps the pump from coming on
when there is not enough water in the tank. It plugs into the outlet and then the pump plugs into that and if the float is not standing up and has
layed over, then the pump will not come on. Kind of like a sump pump switch in reverse.
