Watts LF288A 1in Anti-Siphon Vacuum Breaker

The Watts LF288A is a one-inch anti-siphon vacuum breaker built for potable water systems. It prevents back-siphonage in residential and commercial plumbing installations. Lead-free brass construction meets NSF/ANSI 372 requirements for safe drinking water contact. The silicone disc seal operates reliably across the stated temperature range.

Pressure and temperature limits define the service

Maximum working pressure is 125 psi with a temperature range of 33 to 180 degrees Fahrenheit. The device complies with ANSI A112.1.1, ASSE 1001, CSA B64 and UPC standards for backflow prevention. It is not rated for continuous pressure applications or temperatures outside the listed range. Installers must verify local code acceptance before use.

NPT threads and compact body simplify retrofit work

The NPT connection threads directly into standard one-inch piping without special tools. At three and five-eighths inches high and two and seven-eighths inches wide, the unit fits tight mechanical rooms. The silicone disc float resists chlorine degradation better than some elastomers. Buyers needing a testable double-check assembly or a device rated for continuous supply pressure should select a different product type.
