  • Bronze body resists corrosion for long service life

Product identity

The Legend Valve 105-303 is a 1/2 inch T-453 bronze Y-pattern check valve designed for plumbing systems that require automatic back-flow prevention. It suits installers and maintenance teams working on water supply lines where a compact, reliable non-return fitting is needed.

Compatibility check

Verify that the piping uses a 1/2 inch connection and that the system pressure and temperature fall within the valve's bronze construction limits. Confirm the flow direction matches the Y-pattern orientation and review the California Proposition 65 notices regarding chemical content before installation.

Build integration

The valve installs directly into the line to stop reverse flow without external power or control wiring, freeing the system from manual shut-off steps during pressure changes. Its bronze body resists corrosion in potable water applications, and the Y-pattern body allows inline mounting where space permits a straight-through flow path.

Questions about this item

What comes in the box with the Legend Valve 105-303 and do I need extra fittings?

The valve is supplied as a single 1/2" T-453 bronze Y-pattern check valve. Pipe nipples, thread sealant or solder fittings are not included and must be purchased separately to complete the installation.

Which version of the 105-303 should I choose for a standard residential water line?

The 105-303 is offered in a single 1/2" T-453 bronze Y-pattern configuration. No alternative sizes, pressure classes or end connections are available for this model, so the listed version is the only one to select.

What does the 1/2" T-453 rating mean once the valve is installed in a copper pipe system?

It indicates a half-inch nominal pipe size and a T-453 bronze body designed for Y-pattern flow. The valve will open under forward pressure and close automatically to prevent back-flow in typical hot or cold water plumbing.
