Installation of Well Screens

SECOND MORE ADVANCED METHOD:  You can also install a gravel pack with a well screen if you are using a three inch drill pipe and a 1.25 inch well screen.  Please note this won't work with a two inch drill pipe.   After you drill your hole and have the pipe really loose, pull the drillhead off and put a 1.25 inch well screen pipe down to the bottom of your hole.  Then pour pea gravel down between the two pipes.  Work the three inch pipe up and down as you continue to pour pea gravel.  The three inch pipe will hit on the top of the pea gravel so you can tell how much gravel you have down in the bottom of the hole.  When you have enough to cover the length of the screen and a little more, you are done.

 

Pull up the three inch pipe (be careful not to pull up the 1 1/4 inch pipe inside!) and you are done.  In the diagram below, the well screen is shaded yellow, except for the point which is blue.
