REMEMBER ALL DRUM DRIPS MUST BE DRAINED ROUTINELY DURING FALL AND WINTER MONTHS, EVEN WHEN WATER IS NOT FOUND ON A REGULAR BASIS. In many cases, the frequency of the operation can decrease significantly if a system stays dry.ДЄ quick-opening device, if installed, should be removed temporarily from service prior to draining low points. Likewise, when preparing for cold weather, the auxiliary drains should be operated daily with the frequency of operation decreasing depending on the discharge of accumulated water. Thereafter, it might be possible to decrease the frequency to weekly or longer intervals depending on the volume of water discharged. Auxiliary drains should be operated on a daily basis after a dry sprinkler system operation until several days pass with no discharge of water from the drain valve.

Failure to keep the dry system free of water can result in damage and expensive repairs to both the system and building.ДЄ program for monitoring the condition of the system and the operation of the auxiliary drains should be instituted. Removing water from a dry system is an essential part of a good maintenance program. NOTE THAT THERE MAY BE MULTIPLE DRUM DRIPS ON THE SYSTEM AND ALL NEED TO BE DRAINED. The drum drips are normally located at the lower portions of the system, or where piping elevation changes may occur.

They are installed to collect water that enters the system and provide an easy way for it to be drained. Drum drips typically consist of two 1 inch valves with a short section of two inch pipe between them (see picture). To facilitate draining water out of dry sprinkler systems, most of these systems have drains called drum drips (also referred to as вЂњauxiliary drainsвЂќ, вЂњdrip legsвЂќ or вЂњcondensate drainsвЂќ). When this trapped water freezes within the sprinkler system, the result is often costly due to damaged pipe and/or property. This additional water is typically due to condensation and draining of the water within the system. In addition to the periodic inspections, additional attention is required to remove any water in the system that may potentially freeze. Why is Dry Pipe Fire Sprinkler System Winterization needed? In these dry systems, when a fire occurs, a вЂњdry pipe valveвЂќ operates and allows water to enter the system, replace the air, and be discharged onto the fire. Dry systems, however, are pressurized with air instead of water under normal circumstances within the section of piping that is exposed to freezing conditions. (If you are unsure if you have dry pipe sprinkler systems, refer to your Annual Sprinkler System Inspection Report.)Дry pipe sprinkler systems function in a similar manner to normal вЂњwetвЂќ type sprinkler systems. These areas can include: attics, entry vestibules, outside canopies, and similar areas. What are Dry Pipe Fire Sprinkler Systems?Дry pipe sprinkler systems are utilized in areas of the facility where sprinkler protection is required, but is likely to experience freezing conditions. Dry pipe fire sprinkler system winterization begins with weekly maintenance and includes drum drip draining. Dry pipe fire sprinkler systems are a very effective and reliable component in your fire protection system, however, additional maintenance is required.
