Overview

The pump that has to work when the power does not. A fire almost always takes the electrical supply with it, so a code-compliant system pairs the electric duty pump with a diesel standby that starts on its own batteries and needs nothing from the grid.

It sits idle for most of its life, which is exactly why it is tested on a schedule rather than trusted on assumption.
