The electric pump is to be arranged to be turned on and off at regular intervals by the time switch to administer (fairly) precise and regular water quantities. [1] This approach, used frequently in DIY watering systems, allows financial savings as the water timer can be discarded. For high-end applications, water timers sometimes allow more ...
Comparison of a regular sprinkler (1) and a reverse sprinkler (2) A Feynman sprinkler, also referred to as a Feynman inverse sprinkler or reverse sprinkler, is a sprinkler-like device which is submerged in a tank and made to suck in the surrounding fluid. The question of how such a device would turn was the subject of an intense and remarkably ...
Dry systems require a fire engine to pump water into the system. Most dry systems do not have pre-connected hoses and require firefighters to bring in the hose. In wet systems, there is always water in the pipes and they can be used by anyone. Wet systems will have hoses so building occupants can try and extinguish fires.

Dwight, having no weapons, whips the car with his belt. Jim races out to check that Dwight is not seriously injured, but they snap at him to go away.
A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available ...
Systems are as diverse as the many applications. [4] [5] In general, however, automatic fire suppression systems fall into two categories: engineered and pre-engineered systems. [6] Engineered fire suppression systems are design specific and most commonly used for larger installations where the system is designed for a particular application ...
A jockey pump is sized for a flow less than one sprinkler in order to ensure a system pressure drop significant enough to start the main fire pump. Jockey pumps are typically small multistage centrifugal pumps, and do not have to be listed or certified for fire system application. The control equipment for jockey pumps may however carry approvals.
