How frequently should a low water cutoff (LWCO) water column be blown down?

The low water cutoff (LWCO) is a critical safety device designed to prevent boilers from operating when the water level is too low. Regular maintenance of the LWCO is essential for ensuring its proper functioning and preventing potential hazards, such as boiler overheating or failure.

Blowing down the LWCO water column daily ensures that any sediment, debris, or mineral buildup is removed, allowing for accurate water level readings and proper operation of the safety device. Regular blowdowns help keep the mechanism free from obstructions that could impair its ability to react to low water situations. Daily blowdown aligns with best practices for boiler maintenance, emphasizing safety and reliability.

While other options may suggest less frequent maintenance, they do not provide the same level of assurance that the LWCO will function correctly in critical situations.
