I have a 3/4 hp jet pump in my well that has two lines going to the
well. I had shut it off before I went away for a week because I was
concerned about freezing.
After returning, it no longer pumps any pressure. There is water in
the pump casing I see in the priming plug, so it appears to be
primed. When it runs, it will pump a very small amount of water out
of a hose below the pump. The gauge on the pump casing reads zero,
but does jiggle a little.
My internet investigation indicates to me that it could be a clogged
jet down in the well.
What other possible explanations are there, and how difficult is it
for a couple of guys to pull the black poly drop pipe and replace the
jet if necessary?
