Having a well-established Maintenance Control Program is one of the keys to maintaining the highest levels of safety and protecting the value and operation of your elevator.
While the maintenance and test periods for some components and devices are clearly spelled out, others are not. Unlike earthquake detection or door lock monitoring, pit flood protection is not specifically called out in A17.1 for periodic testing or maintenance intervals.

Pit flood protection devices fall into a unique category, similar to governor switches, where during normal operation it is not immediately obvious if they are not working. A non-functioning device often becomes apparent only when it is needed, which is typically too late.

1.ย ย ย ย ย ย ย ย ย Add pit flood protection devices into your Category 1 testing, similar to governor switches, DLM, and earthquake detection.
2.ย ย ย ย ย ย ย ย ย Test functionality any time a component the pit flood protection device is connected to is changed, especially if the COP button or hall button it is connected to is replaced.
3.ย ย ย ย ย ย ย ย ย Test after any major overhaul.
Pit flood protection has the ability to prevent tens of thousands of dollars in damage to an elevator during flooding caused by a storm or burst pipe. Additionally, it provides an extra layer of safety to passengers by keeping them from descending into a flooded pit. The time to determine whether or not the device is still connected and functioning is before it is needed, not after.
