What is the minimum size of water supply inlet for a dental unit or cuspidor?

The minimum size of the water supply inlet for a dental unit or cuspidor is 3/8 inch. This size is typically required to ensure proper water flow and pressure for the operation of equipment used in dental procedures. A larger diameter allows for better water flow and reduces the risk of clogs or restrictions that can occur with smaller inlets. The 3/8 inch inlet strikes a balance between sufficient flow to accommodate the needs of the dental unit while also fitting within standard plumbing fittings. This consideration is especially important in a clinical setting, where consistent and reliable water supply is crucial for hygiene and function during treatments.
