Randall in Central
Florida reports a successful well using this method! He
drilled 17 feet on his first try. He had a four foot well
screen (1.25") and was initally only able to get it two feet below
his two inch drill pipe. He was able to pump water OK but was
sucking some air.
He removed the well
screen, added some pipe to the top and set that piece aside.
Then he made another 1.25" PVC pipe into a drilling pipe and drilled
eight feet below the bottom of his two inch piece for a total of 25
feet. He quickly removed the 1.25" drill pipe and put
the well screen back down through the two inch pipe. This put
the well screen far enough below the bottom of his two inch piece
that it no longer sucked air.
Randall very cleverly figured out how to put some pea gravel
at the bottom of his well to increase production. Normally it
is impossible to put pea gravel down the space between the 1.25"
well screen pipe and the 2.00" drill pipe. The pea
gravel is just too big. It will stick and not go all the way
to the bottom of the well. I have only been able to pea
gravel down in this manner when I have a 3.00" drill pipe and
a 1.25" well screen pipe.
used what he described as very large screened sand. It is mined in Ocala, Florida, and I buy
direct. As a comparison, most aquarium gravel is about the
same size. I also use this sand in gravity flow filters for my
small garden fish pond. It took a little bumping on the
casing but I was able to pour it in.
Randall's experience can be
instructive for the rest of us. He was somewhat
successful on his first try, but he kept working through problems
until he had a great well.
If you can't find large sand Randall suggests
