Gas shutoff must be located within what distance of the water heater?

The requirement for the gas shutoff to be located within 6 feet of the water heater is based on safety and accessibility. This distance ensures that the shutoff valve can be easily reached in the event of an emergency or a leak, allowing for quick action to prevent accidents or fire hazards.

Having the shutoff valve positioned within this specified distance facilitates prompt accessibility, which is critical in situations where immediate intervention may be necessary to stop gas flow. This proximity helps to minimize risks associated with gas leaks and ensures compliance with plumbing codes that mandate safe practices in gas installations.

The other distances provided in the choices do not meet the regulatory standards set forth for gas installations related to water heaters, thus making the 6-foot requirement the established norm. This guideline emphasizes the importance of both safety and convenience in plumbing practices.
