Cleaning Shallow Well Jet
To remove debris from venturi or nozzle, proceed as
follows:
1. Disassemble pump per instructions on Page 9.
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
similar 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. Reinstall nozzle and venturi. Do not overtighten!
5. Reassemble pump per instructions on Page 9.

How to Handle a Gaseous Well
In some areas well water contains gases which must be
allowed to escape before the water is used. This can be
done as shown in Figure 13.
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 outside of any enclosure.
