Bronze Spring Check Valve

The Milwaukee Valve UP1548T is a 1 1/2 inch solder low lead bronze spring check valve designed for plumbing systems requiring backflow prevention. It features an inline spring mechanism with bronze body and seat materials rated for a maximum temperature of 353 degrees F and maximum water pressure of 250 psi at 150 degrees F.

Horizontal Mounting Only

This valve suits installations where horizontal orientation is specified and cracking pressure between .750 and 1.000 psi is acceptable. It is not rated for steam service, so builders needing steam-rated components should look elsewhere. The bronze construction also makes it unsuitable for applications requiring stainless steel or plastic valve bodies.

Sweat Connection Install

Installation uses sweat x sweat connections requiring standard soldering tools and skills for copper piping. The low lead bronze composition meets relevant safety standards for potable water systems. Common issues include improper horizontal orientation during installation or debris preventing the spring mechanism from seating correctly.

Questions about this item

What pipe size and connection type must my plumbing have for the 1 1/2" sweat-by-sweat valve to fit?

The valve requires 1 1/2 inch copper tubing with sweat connections on both inlet and outlet.

Will the bronze spring and seat hold up if I keep my existing bronze piping?

Yes, the spring and seat are bronze, matching your piping material for compatible corrosion resistance.

How can I confirm the valve is sealing correctly after installation?

Pressurise the line up to 250 psi at 150 °F; the valve should remain closed until pressure reaches .750 to 1.000 psi cracking pressure.
