6. FAQ (Frequently Asked Questions)

Q1: What is the purpose of the three compartments?

A1: The three compartments are designed for the mandatory three-step commercial cleaning process: 1) Washing (soapy water to remove food residue), 2) Rinsing (clear water to remove soap), 3) Sanitizing (disinfectant solution to kill bacteria and ensure safety for reuse).

Q2: Can the compartment sizes be customized?

A2: Yes, we offer customizable compartment sizes (length, width, depth) to fit specific kitchen needs. Equal splits are standard, but unequal splits (e.g., larger first compartment for washing large cookware) are available upon request.

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 the first (washing) compartment to handle food debris efficiently. We provide compatible drain assemblies for easy installation.

Q5: How do I clean and maintain the sink?

A5: For daily cleaning, wipe the compartments 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, undermount for a seamless countertop look, 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, or drain assembly issues). Normal wear and tear, misuse, or damage from harsh chemicals/abuse are not covered under the warranty.
