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

Drinking Water – Flow Markers are used to clearly identify the direction and presence of potable (safe-to-drink) water within plumbing and distribution systems. These markers help maintenance teams, plumbers, and facility managers quickly distinguish drinking water lines from other types of water systems, such as wastewater, irrigation, or non-potable water.

The primary reason for using drinking water flow markers is to prevent cross-contamination and ensure water safety. By clearly marking the flow direction and identifying pipes carrying potable water, these labels help avoid accidental mixing with non-potable sources, which could pose serious health risks.

These markers are typically placed on pipes, valves, pumps, and storage tanks in residential buildings, commercial facilities, hospitals, schools, and any place where clean drinking water is supplied. They are especially important in complex plumbing systems or in facilities with multiple water supplies.

Using drinking water flow markers promotes public health by ensuring that only safe water reaches consumers, supports compliance with health and safety regulations, and simplifies maintenance by providing clear, visual guidance on water flow and source.
