Based on the provided reference, changing the AquaTru water filter involves a few key steps, but without specific instructions for the entire process, a complete answer is difficult to formulate. However, the excerpt does mention the following, related to flushing the system after a filter change:
- Turn on your cold water supply.
- Wait for the arrow tank to fill.
- Repeat steps one and two to flush the system.
- Fill the tank one last time.
This suggests a post-filter replacement process to prepare the AquaTru for use. Because the provided information is limited to this flushing process, I cannot provide a comprehensive guide to changing the filter. More information is needed for a full answer.
