Description

Watts Low-Profile Grease Interceptor – 50 GPM / 100 lb

Model WGI-50-LP • PDI Certified

Keep fats, oils, and grease out of your plumbing system with the Watts WGI-50-LP Grease Interceptor. Engineered for high-volume commercial kitchens, this low-profile unit delivers a 50 gallons-per-minute flow rate while trapping up to 100 lb of grease—all in a durable, epoxy-coated steel body that fits where taller interceptors can’t.

Why You’ll Love It

  • Space-saving low profile: Easier installation under sinks or in tight mechanical rooms.
  • 50 GPM flow rate: Handles busy dish rooms, pot sinks, and combi-oven drains with ease.
  • 100 lb grease capacity: Extends pump-out intervals and lowers maintenance costs.
  • Rugged epoxy-coated steel: Corrosion-resistant finish stands up to harsh kitchen environments.
  • Solid steel gasketed cover: Hex-head center bolts create a positive, splash-proof seal.
  • Removable baffle assembly: Speeds up clean-outs—no tools required.
  • Deep-seal trap with cleanout: Prevents odor escape and allows thorough servicing.
  • External cast-iron flow control: Maintains code-compliant flow and simplifies inspection.
  • No-hub 4" inlet & outlet: Quick connections to cast-iron or PVC DWV piping.
