About 8 or 9 years ago, we had our well serviced and the pump broke off and got wedged in the the well, about 25' from the bottom. So our pump now is actually about 25 feet higher in the well than the original pump. Over the last few years, we've been having increasingly lower and lower well yields, although it does vary seasonally (worse toward the end of Summer and early Fall). Last year, I put in a 1500gallon cistern with a Pumptec Plus and that has worked OK up to this point. However, even when I give the well a long time to recover, the pump will only run for 10 to 15 seconds or so before the Pumptec trips. I suppose that would suggest that the static water level has dropped considerably. I don't know exactly, but I'd estimate that the well yield to be 1gal/min or a little less, when it was 15gallons/min when drilled, nearly 30 years ago. The well is 340ft deep and the pump is now at around 315 feet deep.
I'd like to increase the yield of my well but I'm not sure what the most cost effective and reliable (high chance of success and long term solution) solution would be. Any insight would be appreciated. Here are a few specific questions:
1\ Is it possible to somehow "fish out" the old pump so I could put the pump at the original depth? One driller said he could try to drill through it, but had no idea if that would work or how long it would take.
2\ Would hydrofracturing be a potential solution? I don't know much about it or how much it costs.
3\ Any other potential solutions? Would it make sense to drill another well?
Thanks in advance,
