5 boilers that have failed — Heating Help: The Wall

On large boilers, if only one supply riser is piped, especially if the riser is too small, it can cause an uneven water level. If the supply riser is on the control side, the LWCO won't detect a low water condition on the opposite side of the boiler, so part of the heat exchange surface will overheat, then, when the boiler shuts down and the water line is restored to level, it suddenly gets
