Milwaukee Valve UP1509 check valve

The Milwaukee Valve UP1509 is a 3/8 inch sweat bronze spring check valve designed for residential plumbing installations. It prevents reverse flow in hot or cold water lines and suits contractors or DIYers fitting low-lead components in confined spaces.

Cracking pressure 0.750 to 1.000 psi

This valve opens only when upstream pressure exceeds the 0.750 to 1.000 psi cracking range, so it will not seal against very low back-pressure. Verify that your system pressure stays above this threshold before specifying the part.

Sweat connections need clean copper

Sweat joints require fluxed, oxide-free copper tube and even heat to avoid leaks. The bronze body handles up to 200 degrees F and 300 psi at 150 degrees F, but overheating the joint can damage the internal seat. Install horizontally as marked to ensure proper spring return.
