Water main vents allow trapped air to escape from pressurized water lines, preventing air locks that restrict flow and cause pressure fluctuations. This type of component is typically installed at high points in a water main where air naturally accumulates. Installation is performed by licensed plumbers during new construction, system commissioning, or maintenance service on existing water distribution infrastructure.\u003c\/p\u003e\u003cp\u003eThe 401485 \/ NO. 78 is suited for residential and light commercial water main applications where air release is required to maintain consistent flow and system pressure.
