The swing-type disc mechanism opens under forward flow pressure and closes automatically when flow stops or reverses, protecting pumps, water heaters, and piping from reverse flow damage. Weighing 0.61 pounds, this compact valve connects via a sweat (solder) end connection sized for 3\/4-inch copper tubing. It is a standard choice for licensed plumbers and pipefitters working on residential and light commercial water distribution, hydronic heating, and domestic hot water systems.\u003c\/p\u003e\n\u003cp\u003eThis swing check valve is suited for installation in residential and light commercial plumbing systems where backflow prevention is required. Common applications include domestic water supply lines, water heater outlets, boiler piping, and pump discharge lines using 3\/4-inch copper pipe. The sweat connection style makes it compatible with standard copper tube soldering techniques familiar to any licensed plumber or mechanical contractor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance suitable for potable water and hydronic applications\u003c\/li\u003e\n  \u003cli\u003eSwing-type disc closes automatically on flow reversal, preventing backflow without manual intervention\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch sweat (SWT) end connections for standard copper tube soldering\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.61 pounds, minimizing load on copper piping runs\u003c\/li\u003e\n  \u003cli\u003eCompact body profile fits standard residential and light commercial pipe configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation swing check valve for 3\/4-inch copper sweat plumbing systems in residential and light commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements.
