FINDING THE DEPTH OF YOUR WELL
(For cased shallow wells only)
Tie a small but heavy weight to the end of a piece of string.
Lower the weight into the well until it reaches the bottom.
Take up the slack and mark the string at ground level. Pull
the weight out of the well and measure from the bottom of the
weight to the ground level mark. This is the depth of your well.
Subtract five feet from the depth of your well. This number
should not exceed 25 feet. If it does, it will greatly hinder or
prevent the proper operation of a lawn sprinkler pump.

NOTE: Performance will be reduced slightly by the foot valve; but the use of a foot valve is recommended.
PIPING
Plastic PVC pipe is shown in the illustrations, but galvanized
steel pipe may be used if desired. All piping must be clean
and free of all foreign matter to prevent clogging. ALL JOINTS
AND CONNECTIONS IN THE WELL ASSEMBLY MUST
BE AIRTIGHT. Even a pinhole leak will prevent the proper
operation of the pump (this is the most common problem).
Use thread compound on all threaded joints unless specified
otherwise.
