I have a project for school and need to make a hand water pump. The thing is, it needs to be a "mini" pump. I will be using 2 mini 1 way check valves and a t fitting, but the problem is i cannot find a way to make the actual piston pump. I also need a spring to draw the piston back up so i can manually push it down with my thumb. I need help with spring rate and how to make the pump in general. I was going to use the famous youtube "how to make a pvc pump" but i cannot find his stuff in a small enough size.
Any insight on where i can buy the peices or how i could make them? The flow of water needs to be similair to a spray bottle
