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 a small hole in the side of the pump housing. See Figure 1. This is an anti-airlock valve. If you suspect an air- lock, insert a hat pin or a pipe cleaner into the anti-airlock hole to clean out the debris.
