Wet pipe sprinklers

The most common type of fire sprinkler system is the wet pipe variety. This system is under constant water pressure and the pipes are always filled with water, so it’s constantly ready for a fire emergency. With a wet pipe system a sprinkler head will burst under intense heat, which activates the release of water. Water discharges over the hot spot, protecting the property from spreading fire, smoke or heat. Most of the time it only takes one sprinkler head to fully extinguish a fire.

Wet pipe sprinkler system for your high-rise or office building

Because stagnant water is present at the location of every sprinkler head in a wet pipe system, there is no delay in the release of the water to the affected areas, which means the second a sprinkler head is activated, the fire is immediately suppressed. This is crucial in environments densely populated by people. High-rise and office buildings often require that a wet pipe system be installed for the most reliable protection against fire, drastically reducing the chance that a fire will grow out of control.

Design and engineering for new systems

While the wet pipe system is the most common type, every building is different, which means the design and engineering of a wet pipe system will differ from building to building. Some buildings formerly used as warehouses that have been converted into offices or apartments will require an entirely new system, which means the contractor needs to have the experience necessary to work in difficult and/or unique spaces. Only trust an experienced design and build team to assist you with your wet pipe system.

"I just wanted to say thank you to the both of you for doing your jobs as well as you do. It is a real pleasure dealing with a company with professionals such as you two. My alarm system is inspected and ready to go (on the same day as you received the contract/quote I would like to ad), my sprinkler system is always taken care of without incident (no leaks or valves left open and your technician is always on time), and I still use the subcontractor I found through you guys for the extinguishers. Again, thank you for the excellent job that you do. Be sure to let me know when you do extinguishers in house so I can contact you for a quote."

Installation of wet systems from the point of service to inside protection

Your wet pipe system is run off of your building’s main water supply, which most people never see, and extends to the sprinkler heads that run through apartments, hallways and offices that are easily visible. At Valley Fire Protection, we handle everything from point of service to the entire inside protection components of the system. Following installation, we’ll fully check every part of the system to ensure it’s operating flawlessly, and we’ll return on as needed to check various aspects of the system so that it will operate reliably when needed.

Cost efficient system repair and low maintenance

Aside from their reliability, wet pipe systems’ cost efficiency is one of the biggest perks. Despite the fact that wet pipe systems are quite common and low maintenance, they aren’t without fault, especially as they age. These particular systems aren’t very complex, so repairs are usually quite affordable and can be completed quickly to minimize downtime.

Advantages and disadvantages to using a wet pipe fire sprinkler system

The most frequently raved about aspect of the wet pipe system is that they are simple and reliable. There aren’t that many parts to this system compared to others, which means there is less possibility for malfunction. They are also cost efficient to install and have little cost related to maintenance. In the event of a fire, many systems will take a lot of work to get them up and ready for another emergency, but not a wet pipe system.

On the down side, wet pipe systems can’t be used in areas of the building that aren’t heated because, during the winter months, the water in the pipes will freeze and rupture. The unheated portion of the building must be fitted with a dry pipe system, which is filled with air instead of water. Some of these areas may include an outdoor overhang structure like a docking area or unheated attic.
