Operation / Troubleshooting
AIRLOCKS
When a pump airlocks, it runs but does not move any
water. An airlock will cause the pump to overheat and fail.
This pump has an anti-airlock hole in the bottom of the
pump body. If you suspect an airlock, unplug the pump,
clean out the anti-airlock hole with a paper clip or piece of
wire, and restart the pump.
NOTICE: If the outlet of the discharge hose/pipe is
submerged you must have a 1/8" hole in the discharge hose/
pipe to prevent airlock. This hole must be open to air.
NOTICE: If you move the pump or if the pump airlocks, be
sure to drain the hose before trying to restart the pump.
