A mop sink faucet shall be mounted a minimum of _____________ inches above the finished floor.

A mop sink faucet must be mounted a minimum of 24 inches above the finished floor to ensure proper drainage and to prevent any potential contamination from the mop sink or cleaning materials. This height helps to keep the faucet clear of typical hazards associated with cleaning activities, such as spills or splashes from dirty water. Additionally, having the faucet elevated minimizes the risk of the faucet being damaged during cleaning and allows for more accessible use of the sink without bending excessively.

This standard is in line with plumbing codes that aim to promote hygiene and safety in facilities where mop sinks are commonly used, such as restaurants and commercial kitchens. It's important that any installation conforms to these requirements to comply with local regulations and ensure optimal functionality.
