Buying Guide: Key Purchase Considerations
- Capacity and flow rate: Match the unit’s grease capacity and GPM rating to your kitchen’s output and peak periods. Higher-volume kitchens benefit from larger or dual-tank systems.
- Installation footprint: Under-sink models fit tight spaces, while larger tanks require dedicated cabinet or utility room provisions. Measure available space before purchase.
- Material and durability: Stainless steel offers corrosion resistance and longevity in high-moisture environments. Plastic traps reduce cost but may not be as durable in heavy use.
- Sealing and leakage prevention: Look for tight lids, welded connections, and sealants included in the package to prevent odors and seepage.
- Maintenance features: Automatic cleaning, easy draining, and accessible filter baskets reduce downtime and labor costs.
- Compliance and local codes: Ensure the chosen interceptor meets local wastewater regulations and grease-management requirements.
- Mobility and installation ease: Caster-equipped units aid maneuverability around a busy kitchen; fixed installations may require professional support.
- Cost of ownership: Consider initial price, maintenance parts, and service availability in your region when comparing models.
