Rated to a maximum pressure of 125 psi and a maximum temperature of 180 degrees F, this unit suits demanding hot-water applications. It features a lightweight disc float that closes the atmospheric vent under all flow rates, making it well suited for low-flow installations such as laboratory equipment. A durable silicone disc provides high resistance to heat and water hammer shock while ensuring a tight seat with minimal contact force. The body is brass construction with female threaded connections and stands 3.625 inches tall. Licensed plumbers install this device on potable water systems where backflow prevention is required by code.\u003c\/p\u003e\u003cp\u003eThe WATTS 336416 is appropriate for residential and commercial plumbing systems requiring atmospheric vacuum breaker protection. Its full-size orifice delivers pipe-capacity flow with minimal pressure drop, making it a practical choice for supply lines serving laboratory equipment, utility fixtures, and other low-flow applications. The streamlined internal water passages reduce turbulence and pressure loss across a range of flow conditions. This vacuum breaker is designed for installation on the supply side of fixtures that may be subject to backsiphonage risk.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDisc float closes atmospheric vent at all flow rates to prevent spilling and backsiphonage\u003c\/li\u003e\n\u003cli\u003eSilicone disc resists heat and water hammer shock for long service life\u003c\/li\u003e\n\u003cli\u003eFull-size orifice maintains pipe-capacity flow with minimal pressure loss\u003c\/li\u003e\n\u003cli\u003eBrass body rated to 125 psi and 180 degrees F\u003c\/li\u003e\n\u003cli\u003eFemale threaded connection for straightforward inline installation\u003c\/li\u003e\n\u003cli\u003eCompact profile at 3.625 inches tall suits tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation vacuum breaker for potable water plumbing systems requiring atmospheric backsiphonage protection at 1-inch pipe size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before removing any existing fitting or installing this vacuum breaker.
