All commercial buildings require fire protection — and in most cases, fire sprinkler systems are the solution that works to protect both your property and your people. If your facility has a fire sprinkler system, you may be aware that there are some situations that require it to be drained. Below, we’ll discuss when a fire sprinkler system needs to be drained, how to drain it, and what that process looks like for various types of systems.
There are a number of events that require draining your fire sprinkler system, including:
Improper draining can lead to sprinkler components being damaged. Therefore, it’s important to know each step of the process in order to make sure your fire sprinkler system is drained safely and effectively. For the best results, adhere to the following steps:
Before anything else, you should notify various parties of your plan to drain, how long it’s expected to take, and what precautionary measures you’re taking while your fire sprinkler system’s service is restored. Some important groups to notify include:
And anyone else that may be involved in or affected by your fire sprinkler system being off for any period of time.
The next critical step in the draining process is knowing where your fire sprinkler drains are located. Most fire sprinkler systems have three types of drains: the main drain, the test drain, and the auxiliary drains.
Once you’ve found your drains, it’s also important to figure out where they flow, or where the water goes after your system discharges. This can help you determine if you need to reroute the flow in order to protect against damage in critical areas of your property.
As you may know, the two most common types of fire sprinkler systems are wet and dry. A wet fire sprinkler system always has water in the piping, and is activated whenever the system is triggered by heat. On the other hand, a dry fire sprinkler system is filled with compressed air, and only fills with water when the system is triggered.
Because they operate differently, each of these systems have different protocols for draining. We’ll walk you through them both.
In the case that you need to drain your fire sprinkler system, it’s always best to ask a professional sprinkler service or fire protection company for help. They’re experts in each of these processes, and they can make sure everything is drained properly without any harm to your system.
