Sloan 3396076 VBF-72-A1 Vacuum Breaker Trap Primer

Product Description

The SLOAN 3396076 is a VBF-72-A1 vacuum breaker trap primer designed to maintain water seals in floor drain traps connected to commercial plumbing systems. The trap primer diverts a small amount of water from the flushometer supply line into the floor drain trap each time the fixture is flushed, preventing the trap seal from evaporating and blocking sewer gas from entering occupied spaces. This is a domestic-rated unit built for use in standard commercial and institutional restroom installations. Licensed plumbers and mechanical contractors install this component as part of a compliant drain trap maintenance strategy.

This trap primer is specified for use with SLOAN Royal and Regal 113 and 113-1.6 flushometers. It is well suited for restrooms in commercial office buildings, schools, healthcare facilities, and other institutional settings where floor drains are present but infrequently used. The VBF-72-A1 mounts directly in line with the flushometer supply and activates passively with each flush cycle, requiring no separate controls or power source.

Key Features

• Vacuum breaker design prevents backflow contamination at the trap primer connection

• Maintains floor drain trap seals to block sewer gas intrusion
• Domestic-rated unit for standard commercial restroom applications

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC) requirements for trap primer devices. Shut off the water supply to the flushometer before beginning any disassembly or connection work. Verify the supply line pressure is within the flushometer manufacturer's specified operating range before restoring service. Do not overtighten fittings on the vacuum breaker body, as this can damage the internal seal components.
