Fire Pumps And Valve Rooms: What Are They For?

Fire Pumps and valve rooms are an integral part of a fire sprinkler system. Once you acknowledge how a fire sprinkler system works through sprinkler heads, it’s time to know how water flows through the system. Fire pumps operate on diesel, electricity, or even steam. They provide the necessary pressure for the release of water through sprinkler heads during a fire emergency. They are a critical part and, therefore, require attention in different aspects.

Importance of Fire Pumps

Fire pumps attach to municipal water supply sources. Or, they can also have a connection to a static source of water, such as ponds, lakes, rivers, reservoirs, gravity and water tanks, water towers, or even underground water tanks. They are necessary because as soon as water flows through the sprinkler heads, pressure starts to break.

The fire pumps, working on fuel, ensure standard pressure and, therefore, allow a consistent pressure in the flow of water. This enables pressurized water flow, which is necessary to douse the fires and prevent further spread.

How Do Fire Pumps Work?

Fire pumps have different types that contribute to fire safety services. These different types are:

• Vertical Split Case
• Horizontal Split Case
• Vertical Inline
• End Suction
• Vertical turbine

They work in connection with a jockey pump. A jockey pump maintains an artificial water pressure in the fire sprinkler system pipes. A jockey pump also prevents damage to fire pumps due to a sudden influx of water in the pipes and the sudden provision of pressure.

This implies that fire pumps do not have to keep running. A motor powers the fire pump. The fire pump creates pressure up to a significant level when more of the fire sprinklers are active, or other outlets of water supply are in use for fire emergencies.

The power of the motor operating the fire pump comes from the same municipal electricity supply that the building uses. However, as a contingency, the use of “transfer switch” has a high demand. This switch transfers the power supply of a fire pump to the emergency generator(s) in a building to keep the fire pump running throughout a fire emergency.

Valve Rooms: What are They?

Automatic fire sprinkler systems in commercial or even large residential spaces have the “control valve and drain.” They are generally in a “valve room.” However, the crucial role that they play in fire safety is worth knowing.

The valves control the different fire sprinkler systems in a building. They can isolate one system while running the others. It’s possible to use a control valve and shut down the sprinkler system when there is either a false alarm or the fire is out.

Maintaining these control valves and drains ensures safety from fires. At the same time, it prevents water damage because of an automatic fire sprinkler system.

Maintenance and Testing (NFPA)

The National Fire Protection Association (NFPA) of the US has some rules and codes to run a proper and reliable fire sprinkler system within the buildings. They ensure proper safety and the level of operation that is successful in protecting against fire hazards.

Valve rooms undergo different tests and repairs during their operations. Or, they might have early tests to ensure seamless performance.

The main reasons why fire sprinkler systems in a building fail are due to the failure of the control valves and drains in the valve rooms. Therefore, it is necessary to perform proper tests for a “foolproof” fire safety system.

Two Types of Valves in a Valve Room

1. Indicating Valves

These valves are visible to anyone and suggest some things about the fire sprinkler systems. They tell if a valve is shut or open. If a valve is closed, then the water flow is restricted beyond that part of the valve. Hence, water discharge may not occur through those pipes during a fire emergency. And spotting these valves and then turning them on becomes easy.

2. Non-indicating valve

They are in a valve assembly that sticks with the water supply shafts underground.
