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.
