Product Identity

The Milwaukee Valve 1510T is a 3/4 inch bronze swing check valve designed for residential and light commercial plumbing systems. It prevents backflow in water and steam lines with a 0.750 to 1.000 psi cracking pressure. The valve handles up to 300 psi water pressure at 150 degrees F and 150 psi steam pressure.

Installation Notes

Sweat connections on both ends require copper pipe soldering skills and proper flux application for leak-free joints. The inline swing mechanism allows horizontal or vertical mounting with flow direction clearly marked. PTFE seals resist degradation but demand clean pipe ends to avoid debris preventing full closure.

Suitability

This valve suits plumbers and facility managers needing reliable backflow prevention in hydronic heating, potable water or low-pressure steam circuits. The 18 gpm flow capacity fits standard 3/4 inch service lines. Installers requiring threaded, press-fit or flanged connections must select a different model. Those needing a lift-check mechanism for rapid cycling applications should consider alternative designs.

Questions about this item

How do I verify the valve is sealing properly after I sweat it into the line?

Pressurise the system up to 300 psi water pressure at 150 °F and confirm no leakage past the bronze seat while flow moves in the correct direction.

What comes in the package and what extra fittings or sealant must I purchase?

The box contains only the 3/4 in bronze swing check valve with PTFE seal; sweat copper tubing, flux, solder and any required hangers are sold separately.

Should I choose the horizontal or vertical mounting version for my installation?

This single model 1510T is rated for both horizontal and vertical mounting orientations, so select it regardless of pipe run direction.
