What is a likely cause if the Cl2 stops feeding after the chlorinator storage roof is removed during the summer?

The situation described involves the cessation of chlorine feeding following the removal of the chlorinator storage roof during warmer months. The correct answer highlights that the tank likely became hotter than the manifold.

When the roof is removed, increased exposure to sunlight and ambient temperatures can result in significantly higher temperatures inside the storage tank. Chlorine gas, which is usually in a liquid state under pressure, can become less effective at being delivered if the tank warms up beyond optimal conditions. This heating can lead to increased pressure in the tank, potentially altering the flow dynamics and causing issues with gas delivery through the chlorinator system.

Additionally, a temperature imbalance between the tank and the manifold might create pressure differences that disrupt the feeding mechanism, making it difficult for the system to function as intended. Thus, managing temperature and ensuring that the chlorinator system operates within the recommended thermal ranges is critical for effective chlorine feed.
