Abstract: A detachable vented signaling alarm apparatus is provided which is capable of being attached to a skimmer basket commonly used with pool skimming systems. There are many different configurations and sizes of skimmer baskets with which the present apparatus is capable of attachment merely by drilling a hole generally centrally in the skimmer basket bottom. The detachable signaling alarm may be readily removed from the skimmer basket for various reasons such as pool vacuuming or maintenance and includes a vented stem for minimizing damage to the basket when debris has accumulated therein. An alarm of any type can be used with the vent mechanism for indicating when the skimmer basket is substantially blocked by debris by generating of an alarm condition responsive to airflow through the vent.
