First the background. About two years ago I put in a 1-1/4â€, three foot driven point well at my house for a water supply to water grass. After driving the well point to a depth of 18’, I measured that the water level in the pipe was only eight feet below ground, or 10’ above the well point.
I next flushed the well point by running a water hose down into the well point, which brought up a sandy, gritty looking mixture. I then attached a hand pump, which yielded very little water. The pump handle had a lot of back pressure. So I repeated the process of trying to flush and pump, with the same result. This went on for several weeks, until I ran out of patience.
This past weekend, I decided to give it another try.
After talking with several of my neighbors who have working wells driven to the same depth, I attached a water hose and forced water down the well. I attached a gauge and when I first started the water flow, I had 25 psi of back pressure, which slowly decreased to 10 psi. I repeated the flush and pump cycle, which gave me a little more water, but I still have a lot of backpressure on the pump handle.
So, as a last resort, I jacked the well point up to 12’ and tried again, with no luck. I then jacked the well all the way out to inspect the well point, which is still in good shape. I measured the water level in the hole that was left at 8’ below ground level.
My question is could I have a well point that has an incorrect mesh size for the type of ground that I have? And if so, is it possible to modify the screen without ruining the well point?
Thanks in advance for any information you could pass on.
