Step-by-step explanation:
The maximum distance permitted between an appliance and a manual shutoff valve depends on the specific regulations and codes set by local authorities. However, in general, there are guidelines to ensure safety and efficient operation. For example, in plumbing systems, the distance between an appliance and a manual shutoff valve should be kept as short as possible, ideally within a few feet. This reduces the risk of leaks and allows for easier maintenance and repair.
