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.
