Plumbing fixtures for commercial sink with pre-rinse unit

Abstract

Improved plumbing fixture fittings for commercial sinks having a faucet with a pre-rinse unit includes a universal tap and flexible steel hoses to connect the universal tap of the faucet with the building's source of supply of water to the sink. Special packaging for the pre-rinse fixtures can include a rigid plastic shell that shields at least some of the underlying fittings from the shrink-wrap material that holds the fittings against movement on a rigid substrate. The fittings are pre-assembled before being mounted to the rigid substrate by the shrink-wrap material.
