Note: The first four items are grease traps with flow-control features intended for installation in commercial drainlines. The Black Diamond product listed is a maintenance treatment designed to support trap efficiency and odor management rather than a trap itself.
Zurn GT2700-07-2NH Flow-Control Grease Trap
The Zurn GT2700-07-2NH is designed for 2-inch piping and offers a 7 GPM flow-rate capacity with integrated flow-control features. Constructed from Dura-Coated fabricated steel, this model emphasizes corrosion resistance and durability under demanding commercial kitchen conditions. The secure, slip-resistant cover with a center tie-down assembly helps contain odors and maintain a cleaner work environment. This unit suits smaller kitchens or locations with moderate grease load, providing reliable performance with lower upfront footprint.
Key considerations include ensuring compatibility with existing 2-inch sewer lines, verifying floor-cut requirements, and evaluating long-term maintenance needs. Operators should plan for regular inspection of the cover and seals to maintain odor containment. Installation should account for accessible service clearances for periodic cleaning and replacement of gaskets.
Zurn GT2700-10-2NH Flow-Control Grease Trap
This 2-inch, 10 GPM grease trap expands capacity for busier operations while maintaining robust flow-control features. Dura-Coated fabricated steel construction minimizes corrosion risk in wet, high-temperature kitchen environments. The unit’s secure cover is slip-resistant and designed to minimize odors escaping into the kitchen or prep areas. It is well-suited for mid-sized kitchens with higher grease generation from frying and heavy dishwashing schedules.
When selecting this model, consider space constraints under sinks or near dishwashing stations, as well as access for periodic cleaning. Look for compatible inlet/outlet layouts that align with existing drain configurations and ensure the installation is level to prevent uneven flow and potential trap bypass.
Zurn GT2700-25-3NH Flow-Control Grease Trap
The GT2700-25-3NH extends flow-control capabilities to a 25 GPM capacity, making it suitable for busier commercial kitchens or facilities with multiple washing lines. The durable, corrosion-resistant steel construction and slip-resistant cover with a center tie-down assembly remain standard features, helping to prolong life and reduce odor release during routine maintenance. This model can handle larger volume loads while maintaining effective grease separation and trap performance.
Operational notes include ensuring adequate space for the larger unit and confirming that incoming drains can feed the trap without creating backpressure. Routine checks should focus on baffle integrity and the condition of the cover seals to preserve odor control and prevent splashback during high-flow events.
Zurn GT2700-100-4NH Heavy-Duty Flow-Control Trap
The GT2700-100-4NH is built for high-demand environments, delivering 100 GPM flow-control capability in a 2-inch line. Constructed with Dura-Coated steel to resist corrosion and withstand frequent cleaning cycles, it also features a secured, slip-resistant cover with a center tie-down to minimize odor escape. This option is ideal for large commercial kitchens, commissaries, or facilities with heavy grease loads and strict odor control requirements.
Key purchasing considerations include the available floor space, the expected peak grease load, and maintenance frequency. Operators should plan for more frequent inspections of mechanical seals and flow-control components in high-use kitchens, and verify that the installation location supports easy access for service technicians and maintenance crews.
Black Diamond Stoneworks GET SERIOUS Grease Trap Treatment
This commercially oriented enzyme-based treatment is designed to enhance grease trap performance and odor control by breaking down fats, oils, and grease inside traps and associated lines. The product claims to support steady drainage and reduce odor without relying on harsh chemicals. It is positioned as a maintenance aid rather than a replacement for physical trap capacity or flow-control hardware. For best results, use as part of a regular maintenance program aligned with the trap’s design capacity and the facility’s load profile.
Important considerations include compatibility with existing plumbing and any local disposal regulations. Enzyme treatments work best when paired with proper trap size, routine cleaning, and adherence to recommended dosing schedules. They should not be viewed as a substitute for a properly selected trap with adequate flow-control capacity in high-grease environments.
Buying Guide: Flow-Control Grease Traps And Maintenance
- Flow-rate capacity: Match the trap’s GPM rating to your kitchen’s peak discharge. Under-sizing can cause backpressure and smearing of fats into drains, while over-sizing may incur unnecessary cost and footprint.
- Material durability: Dura-Coated fabricated steel offers corrosion resistance. Consider environments with high humidity, frequent washdowns, or caustic cleaners when selecting materials.
- Cover design and odor control: A secure, slip-resistant cover with a center tie-down helps minimize odors and adds worker safety. Ensure service access is unobstructed for routine cleaning and gasket replacement.
- Installation space and plumbing compatibility: Verify inlet/outlet sizes, floor clearance, and alignment with existing drain lines. Plan for easy access to the unit for maintenance, and ensure proper venting if required by code.
- Maintenance and service plan: Combine sturdy traps with regular cleaning schedules. For larger facilities, implement a preventive maintenance calendar that includes trap inspection, grease removal, and seal checks.
- odor management: In addition to a robust trap, consider enzyme-based treatments or odor-control products as part of a broader odor mitigation program. These should complement, not replace, the trap’s mechanical performance.
- Compliance and lifespan: Check local codes for grease trap requirements and ensure that the chosen model aligns with compliance standards. Durability and warranty coverage can impact long-term total cost of ownership.
Selecting the right combination of a flow-control grease trap and maintenance aids requires evaluating kitchen size, grease load, and service capabilities. Operators should weigh high-capacity models for busier kitchens against smaller, cost-efficient units for compact facilities. Enzyme-based maintenance products can extend trap life and help manage odors when integrated into a regular maintenance regime.
