Sure, there’s the requisite annual maintenance check—but this isn’t the only time to schedule a fire sprinkler system inspection. Malfunctions can creep in when you least expect them, but it’s vital to catch these issues before they turn into full-scale safety hazards, putting lives at risk if a blaze ignites. If you notice these red flags, call a fire sprinkler technician immediately.

1. Corrosion and Rust

Corrosion is one of the most obvious signs that your fire sprinklers need to be serviced. If you see discoloration on the sprinkler heads or plumbing fixtures, schedule a fire sprinkler system inspection as soon as possible. Corrosion will cause more serious damage if you let it spread. Eventually, the issue will disrupt the entire system’s operation. For instance, it could block or burst the plumbing and obstruct water flow from reaching the sprinkler heads.

2. Impact Damage

The sprinkler heads or plumbing can also suffer impact damage from a variety of causes. Even slight dents can be enough to loosen connections or impair the seals. Since this damage can result in total system malfunctions, immediate action is crucial. A fire sprinkler technician can diagnose the extent of an impact, then handle the necessary repairs.

3. Low Water Pressure

A fire sprinkler system leak can indicate low water pressure. Look for inconsistent flow in the plumbing and test the system on a regular basis to ensure all your sprinkler heads are releasing sufficient water. If you notice inadequate water flow, enlist the professionals right away. A fire sprinkler system inspection will detect the culprit behind this low water flow (whether it’s a leak or a blockage), so you’ll have ample time to fix the problem.

4. Loud or Unusual Noises

If you hear an abnormal sound coming from the fire sprinklers, don’t just brush it off. It could be a sign of loose connections, trapped air in the plumbing, and other serious maintenance issues. Bangs, hisses, or rattles are the most common noises to be concerned about—but any sound that’s new or unusual should grab your attention and warrant an inspection.

5. Faulty Valves

Test all fire sprinkler valves about once a week to ensure you can turn them without much effort. You might have to replace a valve that won’t budge or feels resistant. Since a faulty valve can impede water flow in a fire, you’ll want to resolve this issue as soon as possible.

6. False Alarms

If a false alarm activates the fire sprinklers, don’t ignore it as a one-off incident. False alarms can cause unnecessary water damage to your home, business, or personal items. They can also lead to system failure in a critical moment. Problems with the sensors, control mechanisms, or electrical shorts usually cause false alarms. Don’t let these issues persist—restore accuracy with a fire sprinkler system inspection from a trained professional.

Why Schedule a Fire Sprinkler System Inspection?

It’s not uncommon for a maintenance issue to arise unexpectedly, but home or business owners often notice a problem at an inconvenient time, causing them to put the issue out of their minds. However, if a fire occurs in the meantime, you could face significant losses and liability issues due to what initially seemed like just a small oversight. 

Regular fire sprinkler system inspections will safeguard your assets, your finances, and most of all, your building occupants. Staying on top of these inspections is the most effective way to detect the cause of a malfunction and take the right maintenance precautions before an issue can spread or worsen. That peace of mind is truly invaluable.
