Manual Water Pump
I am trying to build a manual water pump in my house. We are digging a well of about 320 feet (about 100m) and are hoping to pump water into an overhead tank that is about 13ft (4m) above the ground. Can anyone help me figure out how to build such a pump. Electricity is and expensive commodity in my area and that is why were looking to use a manual pump. Any input will be appreciated.
