Temperatures were in the mid-90s when the crew pulled up and saw the family trying to get water into the kiddie pool by filling pots with water from the sink.
Without a thought, the fire crew grabbed their hose and helped fill up the pool.
What made the moment even sweeter was when firefighters learned the family wanted to use the pool to help celebrate a young boy's birthday.
The station posted pictures of the simple gesture to Facebook saying, "What was just a simple task for us turned into laughter, smiles, and a life long memory for the neighborhood kids as well as the men on Engine 18. Proud to serve the WESTSIDE!"
