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 boiler damage, or worse, a fire or explosion.
The diagram below was designed specifically for adjusters to help explain how low water cutoffs work and what causes them to fail. This knowledge will help make settling your claims that involve boiler damage easier. To request your copy, simply fill out the form below.
