Cleaning Shallow Well Jet
To remove debris from venturi or nozzle, proceed as follows:
1. Disassemble pump per instructions on Page 8.
2. Turn venturi counterclockwise and remove it. The nozzle is
now exposed. Remove it using a 5/8" hex socket wrench with
extension. Turn counterclockwise. If socket wrench is not
available, insert an ice pick or Kmlllar pointed tool carefully into
the nozzle. This will dislodge debris.
3. Flush out the debris by running water through the nozzle in
the same direction as the dislodging tool was inserted.
4. Replace nozzle and venturi. Do not overtighten!
5. Reassemble per pump instructions on Page 8.

A good way of delivering gas-free water is to suspend a pipe, closed
at the bottom and open at the top, surrounding the suction pipe.
Since the gases rise in the well casing, the water sucked down
through the pipe and into the suction pipe is free of gas. This type
of well must be vented to the outMde of any enclosure.
