What maintenance issue can arise if the discharge valve in an inverted bucket trap is positioned poorly?

A discharge valve positioned poorly in an inverted bucket trap can become susceptible to blockage caused by dirt or scale build-up. Inverted bucket traps rely on the buoyancy of the bucket to determine whether steam or condensate is present. When the valve is not located optimally, it can lead to condensation pooling within the trap or restrict proper drainage. Over time, impurities from the condensate—such as dirt or scale—can accumulate and obstruct the valve, disrupting its function. This blockage impedes the efficient discharge of condensate and can lead to further operational issues, such as reduced efficiency and potential damage to the system.

The other choices may involve different scenarios but do not directly correlate to the implications of a poorly positioned discharge valve in the context of an inverted bucket trap. Understanding that blockage from contaminants is a more common outcome provides insight into the operational integrity of the steam system as a whole.
