CurlyDave,
What is a "clay seal" and how can it be fixed? Raising the pump 20' will cost us approximately $150.

The top of the well casing is "sealed" to the earth with bentonite clay.
In my part of the world, when the well is "finished" about a 75' length of steel well casing is dropped into the hole around the PVC casing that goes all the way to the bottom. A slurry of bentonite clay is then forced into the gap between the steel casing and the earth in order to seal this gap and prevent ground water from falling down the well.
My neighbor had to have his seal replaced about a year ago and the cost was either $1200 or $1800. Not cheap, but water is hard to live without.
