INSTALLATION

If depth of well and the distance to the water level in the
well are not known, proceed as follows: 
1. Tie an object that will float to the end of a ball of string and

drop it into the well. 

2. When float hits water and string becomes slack, mark the

string and pull float from well. Measure distance between
mark and float for the water level in the well.

3. Remove float, replace with a heavy object that will sink in

water and drop it into the well until string becomes slack.
Mark string and pull object from well. 

4. Measure distance between mark and object for depth of

well. 

If drawdown water level is not known, set pump 5 feet from
the bottom of the well. 

Basic Tools and Materials Needed

Study Figures 1 thru 3. Figure 1 shows the piping and elec-
trical connections of a submersible pump in a well. Figure 2
shows typical installation of a Captive Air® Tank System.
Figure 3 shows typical installations of a Standard Air Tank
System.  These illustrations will help you determine what
materials you will need for piping.
