Boiler Room Red Flags: What to Check Before Calling a Tech
That alarm is going off — now what? Before you pick up the phone, there are a few things every operator should check first.
Jude walks through the most common boiler room red flags — high water alarms on the DA, low water on the boiler, flame failures, and more — explaining what each symptom means, how to safely respond, and when it's time to call a tech.
Knowing how to read your alarms, levels, and gauges before a service call saves time, money, and — in the case of low water — can prevent a dangerous situation from getting worse.
WARE's team deals with these exact scenarios every day through their boiler service division. When it's beyond a quick fix, they're the call to make.

Related Search Q&A:
What should I do when a boiler room alarm goes off?
Start with bells, levels, and gauges — find the corresponding alarm light, identify the system affected, and address the symptom (like draining a high DA) before chasing the root cause.
Is it safe to add water to a boiler during a low water condition?
Only if there's water visible in the site glass. If the site glass is dry and the unit is firing, shut it down and let it cool before doing anything else.
Can I reset a flame failure lockout myself?
Generally yes — resetting once or twice to see if it was a hiccup is considered safe practice, but if it keeps locking out, stop and call a service tech.
What causes a high water alarm on a deaerator?
Common causes include a misadjusted setpoint, an open bypass valve, or a leaking heat exchanger sending excess condensate back to the boiler room.
What's the difference between an alarm silencing button and a switch?
A button clears the alarm temporarily but re-triggers if the condition returns; a switch can be left in the off position, masking ongoing problems — buttons are the safer design.
