Test and Confirm Hot Water

What happens here

With all components reassembled, turn on the shower and test the water temperature. The presenter demonstrates that the shower now produces significantly hotter water, indicated by visible steam. The adjustment has successfully increased the maximum hot water output. The video concludes by emphasizing that many modern shower valves include anti-scald devices, and if not correctly set during installation, they can restrict hot water, making this adjustment a common and effective fix.

Goal: Verify the temperature adjustment was successful.
