Low water cutoff valves are designed to detect an unsafe drop in boiler water levels and prevent the boiler from operating without an adequate water supply. If a LWCO is not working properly the boiler can run without the necessary water supply and overheat, which causes significant damage to the boiler, or worse, a fire or explosion.
Without proper maintenance, mineral deposits can collect inside the LWCO and the valve can become stuck. This can present the boiler with a “false positive” that it is safe to continue running. If the boiler continues to run without the necessary water supply (a common condition when pipes become frozen), it can overheat and cause significant damage to the boiler, or worse, a fire or explosion.
