Mechanical-Float LWCO Valves White Paper

Boilers and Low Water Cutoff: Mechanical-Float Valves

Low Water Cutoffs (LWCOs) for boilers are required by code in many states and municipalities, regardless of whether the boiler heating system is in a commercial building or a residence. While more modern LWCOs are typically electronic, many older boilers have mechanical-float valves, which raise and lower with the water level and are attached to a switch. If the water level gets too low, the float moves the switch into the off position, causing the boiler to shut off.

Unfortunately, these LWCOs are prone to failure in a number of different ways, and when they fail, those insurance claims can fall into the laps of adjusters like you. Should you get one of these claims, you’ll want to know what you’re dealing with and what the claim could mean for your customer and your company. You’ll want to know:

• What can go wrong with mechanical-float LWCOs;
• The consequences of these failures;
• How they can cause total and catastrophic system failures;
• The financial impact of LWCO failure; and
• How to prevent such failures.
