Why does a fire engine need to supply water to a fire sprinkler system?
Wiki User
∙ 11y ago
A "fire department connection" (FDC) is often required on a sprinkler or standpipe system in case the ordinary supply of water fails to provide enough pressure for any reason. That way, a fire engine's pump can be used to pressurize the system with water from other sources.

What does deluge mean in a fire sprinkler system?
A deluge fire sprinkler system, unlike most ordinary systems, mean that the sprinkler heads do not have individual heat-sensitive valves. The sprinkler heads in a deluge system have no valves of their own, meaning they are always open and water will be sprayed out of them when the supply valve is turned on. There are limited uses for deluge systems, such as in a tire storage warehouse where it is important to put out a fire quickly and the massive flow of water will not cause major damage.

What is the difference between deluge and other fire sprinkler systems?
In a deluge system the water comes out of all sprinkler heads at once, compared with most fire sprinkler systems in which each sprinkler head has its own heat-sensitive trigger. There are major design differences in how much water you need for a deluge system and what safety interlocks are built into the system to prevent accidental water damage.

How do you de-winterize the sprinkler system?
Attach an air compressor line to the main water supply line or junction point and open or remove all of the sprinkler heads. Then blow air through the lines until all of the water comes out and replace the heads. You can also put a small amount of Plumbing antifreeze in the lowest point in the system to prevent any residual water from collecting and bursting the pipes.
