What is the maximum allowable distance for a shutoff valve to be placed from a water heater in a residential dwelling?

The maximum allowable distance for a shutoff valve to be placed from a water heater in a residential dwelling is 3 feet. This regulation ensures that homeowners can easily access the shutoff valve in case of emergencies, such as a leak or malfunction involving the water heater.

Maintaining this distance is vital for safety and efficiency. If the shutoff valve were placed further than 3 feet, it could make it more challenging to quickly turn off the water supply in an emergency situation, potentially leading to greater water damage or safety hazards.

The standards set forth in plumbing codes emphasize the importance of accessibility for shutoff valves, reinforcing the idea that they should be within a reasonable reach while still allowing for proper installation and operation of the water heater.
