Intent

Intent 1:

To limit the probability that:

  • the lack of pressure-relief valves will lead to water pressure in hot water tanks exceeding the tanks' rated working pressure, or
  • the lack of temperature relief valves will lead to an inability to vent excessively high-temperature water, which could lead to the formation of steam, which could lead to pressure in hot water tanks exceeding the tanks' rated working pressure.

This is to limit the probability of rupture or bursting of storage tanks, which could lead to harm to persons.
