I am a highly skilled home service professional who recently completed a job replacing an existing hybrid water heater with a new Rheem hybrid unit. The replacement process involved removing the old unit, connecting the new unit to the existing domestic water piping, condensate line, and electrical supply, and installing a new mixing valve. The water heater temperature was set to 140°F, and the mixing valve was adjusted to 4.5 to ensure a consistent 120°F supply to household fixtures. After the installation, I provided the customer with a thorough walkthrough of daily operation procedures and recommended long-term and short-term maintenance practices.
