What is the term for the process of adding water to a pool?

The process of adding water to a pool is commonly referred to as a pool refill. This term accurately describes the action of replenishing the water often lost through evaporation, splash-out, or backwashing of the filter. Regularly refilling a pool helps maintain proper water levels, which is essential for the proper functioning of pool equipment and to ensure safe swimming conditions.

While other terms like "water topping off," "water replacement," and "pool refreshing" might seem to convey a similar idea, they aren’t as widely recognized or used in the context of pool maintenance as "pool refill." Each of those alternatives may imply different processes, such as topping off for minor water loss, replacement for a complete drainage and refill, or refreshing which could imply changing out water for quality rather than just quantity.
