Boiler Drain Valve for Plumbing Systems

The Legend Valve 107-154NL is a 1/2 inch T-522 boiler drain valve designed for residential and commercial plumbing installations. It provides a reliable shut-off and drain point for water heaters, boilers and hydronic heating systems. The no-lead brass construction meets current safety standards for potable water applications. This new component suits plumbers and facility managers maintaining hot water distribution networks.

No-Lead Brass Build with Standard Threading

The valve body uses no-lead brass to comply with regulations on drinking water safety. Its 1/2 inch connection integrates directly into standard pipe fittings without adapters, simplifying installation or replacement tasks. The quarter-turn T-522 handle allows quick operation even after long periods of inactivity. California Proposition 65 notices indicate the presence of listed chemicals requiring appropriate handling during installation.

Replaces Worn or Non-Compliant Drain Valves

This unit replaces older boiler drains that leak, seize or contain leaded alloys no longer permitted in potable systems. The upgrade is worth it when a water heater or boiler requires a code-compliant drain point during service or inspection. It is not suited for gas lines, high-pressure steam or applications needing a hose bibb with a vacuum breaker. Buyers needing a different thread size or a full-port ball valve should select an alternative model.

What pipe thread size is needed to mount the 107-154NL boiler drain?

The valve uses a standard half-inch male pipe thread for direct installation into a boiler or tank tapping.
