ok...got the well point down to about 22 feet ( I have about 5 feet of water in the pipe ) and put the pitcher pump on top. Began by priming the pump and started pumping. Got muddy, silty water up as I pumped but I began building up pressure in the pipe and I had to actually hold the pump handle down or else it wanted to suck right back up because there was so much pressure built up in the pipe. At first I thought there was something wrong with the valves in the pitcher pump, but now I just assume that I need to take some time to surge out the well? I have found that I have drilled into a fine sand and that the pounding of the point has probably clogged up the drill point mesh. With that being clogged I am creating a vaccume in the pipe by pumping it with the pitcher pump. This is a reasonable assumption?
This is a very remote area with not other hose to surge the well (or electricity). Which method of surging might work out best for me in this sandy well? Simply churning it till it cleans the mesh point...should I use the check valve on the end of a smaller pipe to surge it to help pull the small particles out...or just churn it and clean it out? I could rent a gas powered compressor to push air down the well to clean the point out too I suppose.
