1/2" Bronze Spring Check Valve

The Milwaukee Valve UP1548T is a 1/2" solder bronze spring check valve for residential and light-commercial plumbing. It prevents reverse flow in hot- and cold-water lines using an inline spring mechanism with a bronze body and bronze seat. The sweat-by-sweat connection suits copper tubing installations where a compact, low-lead component is required.

Suits copper systems needing 250 psi at 150°F

Installers working with 1/2" copper pipe and sweat fittings will find the pressure and temperature ratings match typical domestic supply conditions. The valve is not rated for steam service and its cracking pressure range of 0.750 to 1.000 psi does not suit applications that demand a higher reseating force or a different connection method.

Cracking pressure 0.750 to 1.000 psi

The spring opens between 0.750 and 1.000 psi, determining the minimum forward pressure needed for flow. This single figure decides whether the valve will operate reliably in a given low-pressure circuit or whether a different cracking-pressure model must be selected.

Questions about this item

What pipe size and connection type must my copper piping have for this 1/2" sweat valve?

The valve fits 1/2 inch copper tubing and uses sweat-to-sweat connections for soldering directly into the line.

Will the bronze spring and seat hold up if I keep my older bronze-bodied plumbing components?

Yes, the body, seat, spring and seal are all bronze, so the materials match existing bronze fittings without galvanic concerns.

How can I confirm the check valve is sealing properly after I solder it in?

Pressurise the line up to 250 psi at 150 °F; the valve should open between .750 and 1.000 psi and stop reverse flow completely.
