In my last couple of columns I have reviewed the construction, sizes and unique fittings for typical hydro pneumatic tanks still made today, that were popular before about 1955.
In my first article on this subject, I talked about sizes of tanks, why they are needed in a hydropnuematic system and a variety of tappings that we don’t see in modern tanks.
If you’re a regular reader of this column and you notice the title, you probably think, “Old Schmitt has slipped a cog once again.” If you have never read this before, I want to assure you that is not true and there is a method to my seemingly goofy title.
In my last column, I wrote about developing well screens in cable tool drilled wells and here are a couple more, including perhaps the two most popular methods.
In my last several columns, I discussed selecting a screen for our water well and some installation methods. Having our screen installed, we move onto the next step in constructing a good water well: developing the well and the formation around the well screen.
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).
In my last column, I talked at some length about selecting screen openings and then ended up by describing one installation method: just driving a pointed screen into a water-bearing formation. Now, I am aware that in this day and age many screens are either threaded or glued directly to the bottom of the casing in a rotary hole. This certainly works, but if the screen has the wrong openings or fails for some other reason either at installation or later, it is impossible to pull. I’m going to limit my comments to screens that can be pulled and would be used in a cable tool or hollow rod drilled well.
