Great Basin grease interceptors from Schier Products are compliant with all plumbing codes and have been approved by most municipal pretreatment authorities nationwide. They incorporate Diffusion Flow technology, reducing inlet velocity and creating laminar flow for maximum grease separation and storage efficiency.
