OK here is another test I did. I have a Wayne portable pump. It is
self priming, and hose bibs for the inlet and outlet. I stuck a 10
foot house down the well and sucked all the water out. The water did
not return to it's steady state level until about 3-4 minutes later.
Does this imply the screen is clogged , or there is a problem with the
well? It seems there should be a steady supply of water if I'm sucking
it out with my portable pump.
