Quick review: $24 ebay water pump, 100 PSI 12V for caravans etc

Testing a caravan water pump from ebay, which was $24 delivered. From seller surestars2009

"12V 100PSI 4L/Min High Pressure Diaphragm Water Pump FOR RV / CARAVAN / BOAT"

Turns out be to be well built. Seems to be better value for money than a typical commercial water pump for computer watercooling or anything sold at local hardware stores (eg. Masters/Bunnings).

Minimum effective pumping voltage: ~2.0 volts
Almost silent: 3-4 volts

Supposed nominal operating voltage 9-14 volts (12v standard).
Stays cool at low pumping pressures and has a fan in the motor which is nice.

I recommend an inline fuse if you are powering this from a lead-acid battery.
