•
Air line tubing should be carefully inspected whenever standard pond maintenance is performed.
Adjust, or if required, replace all sections that are pinched, kinked, or damaged.
•
All attached air-driven pond accessories should be regularly maintained. Moving parts should be
kept as clean as possible - remove algae growth and other buildup.
•
Air stones should be kept clean and free of debris or algae buildup. Replace every month for
optimum performance.
Clogged air stones and air-driven pond accessories will lead to low air pressure and also reduce the life of
the diaphragms.
Troubleshooting Tips
If the air pump fails to produce air:
•
Make sure the air pump is plugged in.
•
Make sure there are no blockage in the air line assembly and that all valves allow air passage. If
the air stone produces no air, remove the air line from the pump and check to see if air is being
produced.
•
If there is no output from the air pump, inspect the diaphragm for tears or rips. A ripped or
weakened diaphragm is the most common cause for loss of output. Any opening in the diaphragm
will make it impossible for the pump to produce air for aeration purposes. Always inspect the
diaphragm first before replacing other parts in the pump.
Removing the Pump
Whenever the air pump must be shut off and removed from the aeration system, always take off the air line
before the pump is unplugged. This will prevent water from siphoning back into the pump. If the air line
cannot be removed before unplugging the power cord, raise the pump above the water level.
