STEP 3 - Tip the top of the pump downwards to about 45°. The float should slide to
the top of the pump and open the air valve. Air should be heard going into
the pump. It will exit the inlet fluid check valve (Bottom-loading) or the
outlet check valve (Top-loading).
Caution:
If air is not acceptable in the fluid discharge hose, disconnect the hose before
performing this test.
STEP 4 - Tip the head of the pump upwards past horizontal to 45° from the vertical.
The float should slide to the bottom of the pump and close the air valve.
STEP 5 - Repeat this process 3 or 4 times to ensure the float moves freely and the
air-valve opens and closes. If the pump must be tilted nearly vertical
before the float slide or the air valve moves, open the pump and inspect
for interference.

Pump Support System and Hose Bundling Assembly

A pump support system can be created to support the pump and hoses. The pump support
system uses well caps with various fitting combinations. (See Figure 11)
Though it is possible in some instances to support a downwell pump with only the tubing, a
separate support line is recommended.
Note:
The walls of some wells deform over time. They may trap a downwell
pump. In some of those cases the support line has proven useful when
retrieving the pump.
In addition to supporting the down-well equipment with a support rope, it may be important
to support down-well hoses (in most cases nylon tubing does not need to be supported by the
support line). Since the down-well hoses can weigh more than the pump, particularly in wells
over 50 feet deep with fluid inside the discharge hose, hose support can avoid problems such
as kinking, jamming, and breaking.
