In my last several columns, I have written about selecting the proper openings for a water well screen and some popular installation methods. One thing we must do, however, before installing the screen is equip it with the proper fittings. Screens purchased from a manufacturer or supply house are not going to work as is (with a couple of exceptions).
If we are installing a drive point used when drilling a so-called stab well, that screen is going to have a point built into one end. We would merely thread the screen onto the first length of casing and hammer it into the ground. As these types of installations are not very popular, and indeed in some areas are illegal, I won’t say anything further about drive points. Likewise, if we are going to attach the screen to the bottom of the casing on a rotary-drilled hole, all we need is something to close the bottom end of the screen if it does not come equipped from the factory that way, and either thread, weld or glue it to our casing and in the hole it goes.
