Interesting....have to keep this all in mind if we ever need to redo this well again..........i know the guy that did this had no hand pump but i do recall him filling the pipe with water then quicklly putting a cap on pipe to see if it would hold water and as soon as cap (his palm) was removed all water quickly disappeared.......hmmmmmm anyhow I think as I mentioned before are home free....took longer than it should of but still we are good
