When should you consider draining a pool?

Draining a pool is a significant action that is typically considered when the water balance cannot be restored, especially after a severe contamination event. This can occur in situations such as a harmful chemical imbalance, excessive algae growth, or the introduction of pathogens that cannot be adequately treated through regular chemical balancing methods. In such cases, draining the pool allows for a thorough cleaning and provides an opportunity to refill with fresh water that can be balanced effectively, thereby ensuring the health and safety of users.

While situations like a dirty pool or low water levels may suggest maintenance or adjustments, they do not inherently necessitate draining the pool. In contrast, extended periods of the pool not being in use would not typically lead to a need for draining, as proper maintenance can keep the pool safe and clean during those times. Thus, the most appropriate consideration for draining stems from severe contamination or an inability to restore proper water chemistry.
