Will Testing My Sprinklers Set Them Off? Common Fears, Answered

If you have been putting off booking a fire sprinkler test because you’re worried an engineer will accidentally set the whole system off, you’re not on your own with this one. It’s one of the most common concerns people have about sprinkler testing, but it’s not usually the case. 

Understandably, the thought of water suddenly pouring through your home, flat, or business premises is not that appealing. Then you’ve got the other questions. Will the sprinklers all activate at the same time? Could testing end up causing water damage in your premises? Will the fire alarms go off and start a mass panic?

The short answer is that professional fire sprinkler testing is designed to check your system in a controlled way. It doesn’t just involve turning everything on and then hoping for the best, which is what a lot of people are worried about. 

So, let’s take a look at some of the most common fears surrounding fire sprinkler testing and what actually happens during a professional visit. 

Fear 1: Testing Will Set Off All My Sprinklers

This is the biggest misconception about fire sprinklers, and films as well as other media certainly haven’t helped the cause here. In most conventional sprinkler systems, sprinkler heads operate individually in response to a large amount of heat.

They don’t just all turn on because another sprinkler head has turned on - each one will turn on when it feels necessary. 

What this means is that just because one sprinkler has turned on, does not mean that every sprinkler in the building is going to start spraying water all over the place. The idea of an entire property being instantly flooded because of one small fire is just something that you see in movies. 

It’s also important to understand that professional testing does not normally mean activating every sprinkler head in the building on purpose. Instead, testing will look at things like water flow and pressure through test points, and looking at other parts of the system.

Fire Sprinkler Servicing’s sprinkler testing service can include visual inspections, alarm and flow switch checks, inspections of pumps and water tanks, as well as flow and pressure testing.

The goal is to assess whether the system is capable of operating when it’s needed as it’s intended, without unnecessarily activating the individual sprinkler heads.

Fear 2: Test Will Cause Water Damage

Nobody wants to take a day off of work to have the fire safety system checked, only to come back to soaking wet floors. Luckily, professional testing is planned around the system. 

Engineers are going to use the appropriate valves and test points to carry out the relevant and necessary checks. If testing could interact with a connected alarm, the appropriate notifications and isolations will need to be made prior to this being completed to avoid unnecessary false alarms. But, it would not be right to say that there is no risk at all with these tests.

Older systems, corroded components, and any undiscovered faults can sometimes show up when a system is being tested. But, this is one of the reasons that testing is so important, as without being discovered, there is no way to fix it. 

If you’re able to find a problem during the planned visit, this allows you the opportunity to deal with it before the system is needed in an emergency situation. If repairs are then needed, you can talk to your professional about the next steps that you should take.

Fear 3: The Fire Alarm Will Go Off

In some systems, testing water flow or other components can trigger alarms or monitoring equipment. However, that doesn’t mean a professional engineer arrives, starts the testing, and then just waits to see what happens.

In fact, part of the testing process may involve notifying the necessary people, and then isolating any connected alarm systems where needed before work commences. 

Of course, the exact process is going to depend on the property, and the sprinkler system that is being tested. This further highlights how important it is to have this handled by a professional who understands how the different components work together. 

Fear 4: If There Was A Problem, I’d Already Know About It

This is not always true. Some sprinkler issues are extremely obvious, and others are hidden. For example, a leak that you can see, a damaged sprinkler head, or corroded pipework can be seen and then indicate that further investigation is going to be needed.

Other issues that are less noticeable such as changes in water pressure, issues with valves or pumps, and other things like this are not going to be spotted just by looking at the system quickly. The system can look perfectly fine and in working order, but there is a problem underneath that you don’t see. 

Regular testing gives a professional the opportunity to look closer and see if there are any problems to be found. The aim is not to find problems to make extra work, but to figure out whether the system is ready to do the job it’s needed for, when it’s needed. 

Fear 5: Testing Will Be Disruptive 

This can be a major concern in places like residential buildings, offices, and other properties that are constantly busy. Nobody wants unnecessary alarms, water issues, or any other kind of major disruption throughout their day. 

Professional testing should be planned around this, and usually they can be carried out with minimal disruption. But, before an appointment, it’s helpful to ensure that the engineers are able to access the important parts of the system. If you do have access concerns, specify before the visit.
