6. FAQ (Frequently Asked Questions)

Q1: What is the purpose of the middle drainboard?

A1: The middle drainboard provides a dedicated, built-in space for air-drying cleaned cookware, tableware, and utensils. Its sloped design and built-in drain channel water back into the sink, preventing water pooling and keeping the area clean and dry, eliminating the need for separate drying racks.

Q2: Can the compartment and drainboard sizes be customized?

A2: Yes, we offer full customization for compartment dimensions (length, width, depth), drainboard size, and overall sink size to fit your specific kitchen space and operational needs. Contact our sales team with your requirements for a tailored solution.

Q3: What is the difference between 304 and 316 stainless steel options?

A3: 304 stainless steel is the standard premium option, offering excellent corrosion resistance for most commercial kitchen environments. 316 stainless steel provides superior resistance to salt, harsh chemicals, and extreme humidity, making it ideal for coastal areas or food processing plants using aggressive cleaning agents.

Q4: Is the sink compatible with garbage disposals?

A4: Yes, most models are compatible with standard commercial garbage disposals, typically installed in one of the two compartments (usually the larger one) to handle food debris efficiently. We provide compatible drain assemblies for easy installation.

Q5: How do I clean and maintain the sink and drainboard?

A5: For daily cleaning, wipe the compartments, drainboard, and frame with a damp cloth and mild kitchen detergent, then dry immediately to prevent water spots. Remove and clean strainer baskets regularly to prevent clogs. Avoid abrasive cleaners or harsh chemicals (e.g., bleach) that can damage the stainless steel finish.

Q6: Does the sink come with overflow drains?

A6: Overflow drains are an optional feature for each compartment. They help prevent water spillage if compartments are filled too full, making them ideal for busy kitchens where staff may be multitasking. Contact us to request overflow drains.

Q7: What installation options are available?

A7: The sink is available in three installation types: drop-in (top-mount) for easy retrofitting of existing countertops, undermount for a seamless, easy-to-clean countertop transition, and free-standing (with legs) for spaces without existing countertops. All installation hardware is included.

Q8: What is the warranty for this sink?

A8: We provide a 1-2 year warranty covering manufacturing defects (e.g., rust, corrosion, compartment warping, drain assembly issues, or drainboard damage). Normal wear and tear, misuse, or damage from harsh chemicals/abuse are not covered under the warranty.
