What is the maximum distance allowed between a gas shutoff valve and the appliance it serves, unless located at the manifold?

• A. 3 feet
• B. 6 feet
• C. 10 feet
• D. 12 feet

Answer: (B)

The maximum distance allowed between a gas shutoff valve and the appliance it serves is determined by safety standards and plumbing codes. In this case, the correct answer is 6 feet. This distance is established to ensure that the shutoff valve is easily accessible for emergency situations or maintenance without requiring excessive effort or time to reach it.

Positioning the valve within this distance allows for prompt access in case of a gas leak or other emergency, which is critical for maintaining safety within residential settings. The 6-foot requirement balances the need for safety with the practicalities of installation and usage, ensuring that homeowners can quickly locate and operate the valve if necessary.

Values less than or greater than 6 feet do not comply with these safety standards, as having a shutoff valve too far from an appliance could impede timely response to gas emergencies. Furthermore, having standards for placement helps in maintaining consistency and safety across various installations.
