Dry Pipe Fire Sprinkler Systems are a bit more complicated than a Wet Pipe System. Pre-action pipes start out as dry pipes. How Do They Work.

While the system is connected to a water source the water is held back by a dry pipe valve which remains closed until the system is activated. This system is considered a pre-action system and it reduces the time. A pre-action fire sprinkler system is a type of sprinkler that requires a two-step process in order to discharge.

When the actual temperature in. First a heat detector or smoke detector working independently from the head triggers the system and water flows into the pipes. They hold water back using an electronic pre-action valve.

This is why dry pipe sprinkler systems need to fill quickly with water. Once a fire detection event occurs the mechanically latched valve opens and water is released. Once the in-ground home sprinkler system is activated water travels through the PVC pipes and is released through the rotating sprinklers.

To ensure the barrel of. This drops down and pops off allowing the water stored in the back end pipe network to be. Dry sprinklers must be long enough to avoid freezing the water-filled pipes due to conduction along the barrel.
