Hot water heaters must be turned down or there must be a tempering valve or an anti-scalding device on the faucets used by children so that the temperature of hot water supplied to sinks does not exceed 120 degrees Fahrenheit (94.2 degrees Celsius).
Authorized agents shall take into consideration that slight variations in water temperature will be expected, as water heaters fluctuate throughout the day and thermometers used to measure water temperature may also result in slightly different readings.
Verbal warnings should be issued rather than written correction orders when temperatures are between 120 and 125 degrees Fahrenheit.
