What is the usual suggested location for a horizontal valve stem?

The typical recommendation for the placement of a horizontal valve stem is at chest height. This positioning is designed to ensure easy access and operation, allowing the user to manipulate the valve without excessive bending or stretching, which can lead to discomfort or injury over time. Having the valve stem at chest height optimizes visibility and leverage when opening or closing the valve, facilitating safer and more efficient operation.

An overhead level placement could lead to difficulties in operation due to the need for raising arms considerably, which can be awkward and tiring. A ground level valve stem may also pose challenges, requiring users to bend down, which is not ergonomic and can be hazardous, especially in tight spaces or where visibility is obstructed. Waist height, while better than ground level, still may not provide the same ease of access and control that chest height does, particularly for users of varying heights.
