FAQ’s Wet & Dry Fire Sprinkler Systems

What is the difference between a wet and dry sprinkler system?

Both wet and dry sprinkler systems extinguish fires using water, just in different ways. In a wet system, the pipes are filled with pressurized water. … When a dry sprinkler system goes off, the pressure in the pipes drops, a valve opens, and water flows through the pipes and out to extinguish the fire.

How does a wet fire sprinkler system work?

wet fire sprinkler system means that, at all times, the overhead fire sprinkler piping is filled with pressurized water. When a fire occurs and the heat activates the sprinklers, water immediately sprays from the activated sprinkler heads.

What causes a wet pipe sprinkler system to activate?

When the air around a sprinkler reaches a certain temperature, the liquid inside the bulb expands until the pressure causes the glass to break. In wet sprinkler systems, pressurized water in the pipes then forces out the plug and flows over a deflector plate that sprays it onto the fire in a carefully designed pattern.

At what temperature does a fire sprinkler go off?

Fire sprinkler systems are actually quite sophisticated, and are designed to be heat sensitive so that sprinklers only activate when the temperatures rise to fire-induced temps, usually somewhere between 68 to 74 degrees Celsius

Why use a dry sprinkler system?

Advantages of using dry pipe fire sprinkler systems include: Many people view dry pipe sprinklers as advantageous for protection of collections and other water sensitive areas. This perceived benefit is due to a fear that a physically damaged wet pipe system will leak while dry pipe systems will notdry sprinkler system

What is a dry standpipe?

Dry standpipes are not filled with water until needed in fire fighting. Fire fighters often bring hoses in with them and attach them to standpipe outlets located along the pipe throughout the structure. This type of standpipe may also be installed horizontally on bridges.

How much does fire sprinkler system cost?

The price of a fire sprinkler system varies based on the size and type of fire sprinklers you install. In general, here are the costs you can expect: $1.50 to $2.50 per sprinklered square foot for new construction projects. $2.50 to $9 per sprinklered square foot for retrofitting existing homes and businesses.
