Legend Valve 101-304 Brass Vertical Check Valve 0.5 in

Product Description

The LEGEND VALVE 101-304 is a threaded brass vertical check valve designed to allow one-directional flow and prevent backflow in plumbing and fluid-handling systems. The vertical orientation suits installations where the pipe run is configured for upward flow, and the brass body provides reliable corrosion resistance in potable water and general plumbing service. At a half-inch pipe size, this valve fits common residential and light commercial branch lines. Licensed plumbers and pipefitters install this valve where backflow prevention is required without the footprint of a full backflow preventer assembly.

This check valve is suited for residential and light commercial plumbing systems, including water supply lines, HVAC hydronic circuits, and general fluid-handling applications that require a compact, inline backflow prevention solution. The threaded end connections allow direct installation into standard half-inch threaded pipe configurations. The vertical check design is particularly appropriate for riser and supply applications where flow direction is consistently upward.

Key Features

• Brass body construction for corrosion resistance in water service
• Vertical check configuration supports upward-flow installations
• Threaded end connections for straightforward installation into standard pipe
• Half-inch pipe size fits common residential and light commercial branch lines
• Compact design suits tight plumbing spaces

Compatibility

Designed as an OEM-style replacement or direct-install check valve for half-inch threaded plumbing systems requiring vertical backflow prevention.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure completely before removing any existing valve or fitting. Ensure the flow-direction arrow on the valve body is aligned with the intended flow direction before making up threaded connections. Use appropriate thread sealant or PTFE tape on all threaded joints and inspect for leaks after restoring system pressure.
