Product Identity

The Legend Valve 105-304NL is a 3/4 inch Y-pattern check valve made from no-lead bronze. It is designed to prevent reverse flow in potable water piping systems. The T-453 model meets no-lead requirements for safe drinking water installations.

Suitable Installations

This valve suits plumbers and contractors fitting 3/4 inch copper or threaded piping where a compact Y-pattern body is required. It is not for applications needing a swing-check mechanism, a larger pipe diameter, or a valve body rated for steam service.

Decisive Specification

The no-lead bronze construction is the single specification that determines suitability for potable water systems. This material satisfies the legal mandate for drinking water safety where lead-free components are compulsory.

Highlights

  • No-lead bronze construction reduces lead exposure
  • Y-pattern design promotes smooth flow direction
  • 3/4 inch T-453 sizing fits standard plumbing
  • California Prop 65 listed for chemical awareness
  • New condition ensures reliable out-of-box performance

Questions about this item

What pipe size and thread type must my plumbing have for the 3/4" T-453 valve to connect?

The valve uses a 3/4 inch connection with a Y-pattern body, so your supply lines must match that nominal size and thread standard for a direct fit.

Will the no-lead bronze body of the 105-304NL valve react with older copper or brass fittings I keep in the system?

No-lead bronze is compatible with standard copper and brass plumbing; it meets low-lead requirements and will not cause galvanic issues with those existing metals.

How can I confirm the check valve is sealing properly after I install the T-453 model?

Pressurise the line and verify flow moves only in the arrow direction; no reverse leakage or water hammer indicates the spring-loaded disc is seating correctly.
