have just purchased an old (deep well)hand pump - approx. 50 - 60 years old for my Dad. it is in working condition - almost. my brother who is trying to install is looking for certain parts - he doesnt really know what they are and neither do i (of course) - my understanding is that they would be for at the bottom of the pipes in the water, but i may be totally wrong. what i believe would help him out the most would be a diagram of all parts and pieces required, from the actual hand pump to whatever is required on the bottom of the hoses/pipes that are in the water. does any one know of a site where i can find something like this? or help me out with their own knowledge? it would be greatly appreciated. Thank You!!!
