OPERATION

C. Pull insert into cavity as shown in Figure 14.

D. Clean out any surplus Permatex from insert cavity

where new seal will be located. See Figure 15.

Cleaning Impeller

1. Follow steps 1A through 1D under “Disassembly and

Assembly of Pump” on Page 6.

2. Remove diffuser and impeller from pump per instructions

under “Removing Motor for Service and Replacing Shaft
Seal” on Page 6.

3. Clean impeller and reassemble impeller and diffuser per

instructions under “Removing Motor for Serivce and

Cleaning Shallow Well Jet

To remove debris from venturi or nozzle, proceed as fol-
lows:

1. Disassemble pump per instructions on Page 6.

2. Turn venturi counterclockwise and remove it. The noz-

zle 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. Replace nozzle and venturi. 

Do not overtighten!

5. Reassemble per pump instructions on Page 6.

HELPFUL HINTS

How to Handle a Gaseous Well

In some areas well water contains gases which must be al-
lowed to escape before the water is used. This can be done
as shown in Figure 16.

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.

Air Control in Flowing Wells

Flowing wells, or wells with little or no drawdown, could
create a special problem in air control in the operation of
your water system.

In such cases, install a Captive Air® Tank. It does not require
any air control.
