How do hand pump wells work?
The upward movement of the disc "sucks" the liquid into the pumping chamber. When the handle is pulled upwards the opposite lever action on the disk then forces the water out of the chamber through a spout located at the top of the hand pump.

When was the hand pump used?
The pump principle has changed little since its inception, whether for the piston pump invented in 275 BC by Ctesibius, or the rope pump invented in the 1st century BC in China. These pumps were still commonly used in the countryside in the United States and Europe in the 19th century.

Is hand pump water safe to drink?
If such water is not filtered and purified, consumption of it might lead to gastrointestinal or other water-borne diseases. ... A hand pump opens access to deeper groundwater that is often not polluted and also improves the safety of a well by protecting the water source from contaminated buckets.

Thank you so much...
