There are two different types of fire sprinkler systems. One involves having pressurized water in the pipes at all times, ready to spray, while the other is more of a “water on demand” system. Each system has its advantages and disadvantages.

In use for many years, the wet fire sprinkler system reacts much more quickly when there is a fire as the water is already in the lines and pressurized. Although this sounds good, it does introduce a few problems. Leaks are more likely to develop since the water is, after all, constantly pressurized. As that water is stagnate for long periods of time, it is also the perfect breeding ground for mold and other unwanted biological growth which can also eat into the lines and cause leaks. Because of this, the system has to be maintained on a routine schedule that includes a periodic draining and refilling of the pipes.

Heat is also mandatory to prevent the water within the wet system from freezing since, in many areas, freezing temperatures are not uncommon. To prevent the pipes from bursting when, for whatever reason, the building's heat fails, the lines are usually drained until the heat is again back on line.

It is a proven fact that fire sprinklers and smoke detectors minimize damage and loss of life in homes. Smoke detectors alert the residents, giving them time to escape and fire sprinklers will at the very least slow the spread of the fire until the firefighters arrive on the scene. Unfortunately, not all homes are set up this way and not all homeowners can afford the expense involved. There is no question that the systems work but they must first be made available to the homeowners. Once these systems are common to all homes, deaths and losses from fires will be significantly reduced; a goal most certainly worth pursuing.
