Frequently Asked Questions

Why is "low water cutoff" testing the most important safety check?

A low water cutoff (LWCO) is a safety device designed to shut down the burner if the water level in the boiler drops too low. If the boiler continues to fire without water, the metal will overheat rapidly—a condition known as a “dry fire”—which can cause the cast iron sections to crack or even lead to a catastrophic explosion if cold water is suddenly introduced. During maintenance, a technician manually triggers this sensor to ensure it is clear of sediment and capable of killing the power instantly in an emergency.

What is "system surging," and how does cleaning the sight glass help?

In steam boiler systems, the sight glass allows you to see the water level and its condition. If the water appears brown, foamy, or is bouncing violently (surging), it indicates that oils, minerals, or pipe dope have contaminated the water. Contaminated water has higher surface tension, which prevents steam from escaping smoothly and causes water to be “thrown” into the pipes, leading to loud banging and inefficient heating. Maintenance involves “skimming” the surface of the water to remove these impurities and flushing the sight glass to ensure an accurate reading.

How does checking the "expansion tank" prevent relief valve leaks?

As water is heated in a closed system, it expands. The expansion tank contains a rubber bladder with a cushion of air designed to absorb this extra volume. During a tune-up, a technician must check the “pre-charge” pressure of this tank. If the air cushion has leaked out or the bladder has ruptured, the expanding water will have nowhere to go, causing the pressure to spike and trip the pressure relief valve. If your boiler frequently “drips” from the relief pipe, it’s usually a sign that the expansion tank needs to be serviced or replaced.
