1" No-Lead Brass Swing Check Valve

The Legend Valve 105-105NL is a 1-inch T-451 no-lead brass swing check valve designed for potable water plumbing systems. It prevents backflow in residential and commercial supply lines where lead-free components are required by code.

Installation and common issues

The valve uses standard NPT threads for inline installation on horizontal or vertical pipe runs with proper flow orientation. A common issue is debris preventing the swing disc from seating fully, which allows reverse flow and noise.

Lead-free compliance

The no-lead brass construction meets California Proposition 65 requirements for reduced lead content, though the product carries warnings for chemicals known to cause cancer and reproductive harm. This specification determines suitability for drinking water applications.

Questions about this item

How can I confirm the 1" T-451 no lead check valve is working after installation?

Run water through the line and verify flow moves in only one direction; the swing mechanism should close silently when pressure stops, with no back-flow or leakage at the 1 inch connections.

What comes in the box with the Legend Valve 105-105NL and what must I supply?

The valve body is supplied; you must provide compatible 1 inch pipe fittings, thread sealant or tape, and any required mounting hardware for your plumbing layout.

Which version of the 105-105NL should I choose for a potable water system?

Select the no lead brass T-451 model; it meets low-lead requirements for drinking water, while the standard brass version does not.
