A plumbing valve cover is disclosed for use in conjunction with under-sink plumbing to avoid interference with the operation of a flexible spray nozzle hose used in conjunction with a spray nozzle. The plumbing valve cover may be coupled to the under-sink plumbing or cabinet wall. The plumbing valve cover may partially cover the under-sink plumbing and include clearances for multiple plumbing lines which may exit a supply valve via either the top, bottom, or sides. The preferred embodiment would be a single piece, injection molded plastic apparatus comprising a horizontal member which covers the top of the valve and two vertical members. The vertical members would be angled or curved to redirect the flexible hose away from getting caught on the valve. The horizontal member can include a pitch to redirect the hose away from the cover or valve when the hose is being retracted into the cabinet.
