What is the maximum temperature of hot water entering the sanitary system?

The maximum temperature of hot water entering the sanitary system is established to prevent damage to plumbing systems, ensure safety, and protect public health. A temperature exceeding 150 degrees Fahrenheit can lead to an increased risk of scalding injuries, particularly for vulnerable populations such as children and the elderly. Additionally, such high temperatures can adversely affect the durability and longevity of various plumbing materials, increasing the risk of leaks or failure.

Furthermore, plumbing codes often dictate that water heated to excessively high temperatures can also impact the performance of drainage systems. Maintaining the temperature at or below 150 degrees ensures that the materials used in pipes and fittings, such as PVC or similar types, are not subjected to conditions that may compromise their strength or integrity.

In summary, keeping the hot water temperature at a maximum of 150 degrees Fahrenheit is crucial from both a safety and a material longevity perspective, making it the correct choice in this context.
