SKU CH-NM5Y-5QZE1

3/4-inch no-lead bronze Y-pattern check valve prevents backflow in plumbing systems

  • No-lead bronze construction for safer potable water systems
  • Y-pattern design reduces flow resistance in plumbing lines
  • 3/4 inch connection fits standard residential and commercial piping
  • California Proposition 65 compliance disclosed for informed handling
  • Legend Valve manufacturing for reliable backflow prevention

Valve Type and Application

The Legend Valve 105-404NL is a 3/4 inch Y-pattern check valve designed for plumbing installations where backflow prevention is required. It suits contractors and maintenance teams fitting new or replacement components in potable water systems.

No-Lead Bronze Standard Limits

The valve body uses no-lead bronze construction to meet Proposition 65 warnings regarding chemicals known to cause cancer and reproductive harm. This material satisfies current no-lead mandates but does not alter the pressure or temperature boundaries of the S-453 design.

Installation Compatibility Checks

Verify that the 3/4 inch connection matches the existing pipe size and thread type before ordering. Confirm the Y-pattern orientation fits the available space and flow direction, and ensure the no-lead alloy aligns with local code requirements for the intended service.

Questions about this item

Should I choose the 3/4" S-453 No Lead Bronze Y-Pattern Check Valve or a different size for my plumbing system?

Select the 3/4" S-453 No Lead Bronze Y-Pattern Check Valve when your piping uses 3/4 inch connections and you need a no-lead bronze body with Y-pattern flow; other sizes or patterns will not match this specification.

How does the 3/4" Y-pattern design affect flow and installation in a real plumbing line?

The 3/4" Y-pattern body keeps flow direction straight with a slight angle, reducing turbulence and pressure drop while allowing the check mechanism to seat reliably in horizontal or vertical runs.

What does the S-453 no-lead bronze rating cap in terms of potable-water compliance?

The S-453 no-lead bronze construction meets low-lead requirements for potable water systems, limiting lead content to the regulatory maximum so the valve can be used on drinking-water lines.
