Buying decisions for grease interceptors with flow control should consider flow rate requirements, space availability, and maintenance practices. Durable steel construction and corrosion resistance extend service life in demanding commercial settings. Models offering external vented inlet flow control can help minimize odors and improve trap performance. For retrofits, under-sink installations may be preferable, while larger operations may benefit from higher GPM-rated units with longer service cycles.

Buying Guide: Flow Control Fittings For Grease Interceptors

  • Flow rate alignment: Match the unit’s GPM rating to your peak kitchen discharge to prevent overloads and ensure consistent separation of grease and solids.
  • Inlet/outlet configuration: No-hub connections simplify installation but verify compatibility with existing piping and seals to avoid leaks.
  • Durability and coating: Dura-coated or corrosion-resistant steel prolongs life in harsh wastewater environments and reduces maintenance costs.
  • Access and odor control: A secure, slip-resistant cover with reliable latches and tie-downs minimizes odors and vandalism risk while allowing quick service access.
  • Footprint and installation: Consider space constraints under sinks or in equipment rooms. Low-profile or compact designs help maximize usable area.
  • Code compliance: Ensure the selected model meets local plumbing codes and restaurant regulations for grease interceptors and flow control devices.
  • Maintenance and accessibility: Favor units with clear baffle access and serviceable components to simplify cleaning and inspection schedules.
  • Warranty and support: Check manufacturer warranties and the availability of replacement parts and service support.
