Arrowhead Brass 220LF 3/4" Female Lead-Free Boiler Drain Valve

Arrowhead Brass 220LF 3/4" Female Lead-Free Boiler Drain Valve

The Arrowhead Brass 220LF is a 3/4" female-connection boiler drain valve built for rough-in and mechanical room installations where a compact, reliable shutoff and drain point is needed on boiler, tank, or hydronic piping. Designated "LF" for lead-free construction, the 220LF is sized to thread directly onto 3/4" female pipe connections, giving plumbers and mechanical contractors a straightforward point-of-connection valve for draining or servicing closed-loop systems. As a purpose-built boiler drain, it is intended to be installed behind the wall or at the base of mechanical equipment rather than as a visible fixture, and it is engineered for dependable operation in the type of low-profile service locations common to boiler rooms, utility closets, and mechanical chases.
