AIRLOCKS
(FIGURE 2)
When a pump airlocks, it runs but does not move any water.
An airlock will cause the pump to overheat and fail. The pump
has a built in anti-airlock hole. See the exploded view on the
repair parts page for the location of the hole. Water leakage
from the anti-airlock hole is normal.
If you suspect an airlock, unplug the pump, clean out the
anti-airlock hole with a paper clip or a piece of wire, and
restart the pump.
