I'm interested in building a ram pump to pump water from a creek that runs at the bottom of my property to the top where i'm going to make my little homestead. I've seen allot of stuff online on building DIY ram pumps and I had a few questions.
Do I have to use a metal feed pipe as people suggest or can I use plastic?
As I understand it, the distance the water can be pumped is a function of the force that the water in the feed pipe can exert. The rule of thumb is to make the feed pipe twice the output pipe, but if I had two feed pipes, would that not double the force, and there fore double the distance?
What is the purpose of the stand pipe, will a stand pipe increase the distance the pup will pump?
Here are some of the resources I've found
as well as numerous other youtube videos, describing the construction but not the theory.
