Zurn GT2700256EXT Grease Trap Extension 25 Gpm

Product Description

The ZURN GT2700256EXT is a grease trap extension designed to increase the depth of compatible ZURN GT2700-series grease interceptors. This extension allows installers to adjust the interceptor assembly to meet site-specific burial depth or riser requirements without replacing the full unit. Rated for 25 GPM flow capacity and sized at 6 inches, it is a field-used component typically installed by licensed plumbers during new construction or retrofit projects where interceptor depth must be brought to grade or meet local code clearances.

This extension is suited for commercial plumbing applications where grease interceptors are installed below grade in kitchens, food service facilities, and other commercial environments that generate FOG (fats, oils, and grease) waste. It is used when the standard interceptor depth does not reach the required service access elevation, making it a practical solution for both new installs and upgrades to existing systems.

Key Features

• 25 GPM rated flow capacity matches the GT2700-25 interceptor series
• 6-inch extension height for depth adjustment at the interceptor riser
• Designed for below-grade grease interceptor installations in commercial settings
• Allows grade-level access compliance without altering the base interceptor unit

Compatibility

Designed as an OEM-style extension component for use with ZURN GT2700-series 25 GPM grease interceptors requiring riser depth adjustment.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC) as applicable. Shut off water supply and ensure the interceptor is depressurized and emptied before servicing or adding extension components. Verify that the extension is fully seated and sealed to prevent leakage at the joint. Always confirm final assembly depth and access elevation meets local authority having jurisdiction (AHJ) requirements before backfilling.
