Answer:
The difference between preventive vertical fire sprinklers and pendant sprinklers is the position each of these sprinklers takes in the water line.
Step-by-step explanation:
A vertical sprinkler is located on the pipe. Due to their configuration, vertical and pendant sprinklers are classified as distribution sprinklers. Both sprinklers use a design in which they spray water in an equal pattern from their positions. On the other hand, a vertical sprinkler has a water deflector on top that allows water to shoot upward. The pendant type hangs from a pipe, and its water baffle is placed at the bottom, but both sprinklers have the same circular pattern.
