electric inline water pump?

my "new" (to me, anyway, as of a month and a half ago) has two cisterns
to collect rainwater runoff from the roof of the house. They're just
sitting on concrete pads above grade. The PO's I think only used them
for watering plants. Let's say I wanted to wash my car, is there an
inexpensive portable electric pump that I could use? (I say portable
because I'd like to be able to only buy one pump but use it at either
cistern if I so desired.) Both just have a spigot for discharge.

Or, if you're serious about "inexpensive", you can get a
fitting for an electric drill that regular
garden hose attaches to. Search on "drill pump".

Put a power cord and handle on it and you're portable. Gives you a pump
designed to produce decent pressure at lower flow rates unlike typical
portable submersibles which are designed for higher flow at lower
pressures. Pressure switch and accumulator tank so you don't have issues
with a pump overheating when you have the nozzle shut off.

Looks like a real overkill just to wash a car. Look at the other pumps at
Harbor Freight.

It isn't. If you were using the pump to pump water to garden sprinklers
one of the other pumps would work ok. Since he want's to wash the car,
you have the issue of the hose nozzle shutting off while he soaps the
car and the other pumps won't handle this condition well and can
overheat. With the well pump setup the pump shuts off when it fills the
accumulator tank to pressure and will restart smoothly as the
accumulator provides the initial flow when you turn on the nozzle again.

That looks perfect! Have you used one, or did you just DAGS? I have to
admit I'm a little skeptical of HF products that don't carry major brand
labels, but I'm willing to try it for the price.
