Fresh Water - Flow Marker (Pack of 5) - Safety Signs by Caledonia Signs

Fresh Water – Flow Markers are important because they clearly identify the flow direction of fresh, potable water within plumbing and distribution systems. This helps prevent confusion with other water types such as recycled, grey, or wastewater, which is critical for maintaining water quality and safety.

Using these markers ensures that maintenance personnel, plumbers, and operators can quickly and accurately trace fresh water lines during repairs, inspections, or emergencies. Correct identification helps avoid cross-contamination, improper connections, and mistakes that could compromise the safety of the water supply.

Fresh water flow markers are typically used on pipes, valves, pumps, and storage tanks in residential, commercial, and industrial buildings, as well as in water treatment plants and irrigation systems. They are especially vital in complex networks where multiple water sources or types are managed.

By providing clear visual guidance, fresh water flow markers promote safe water handling, support regulatory compliance, and help maintain the integrity and reliability of fresh water distribution systems.
