6. FAQ (Frequently Asked Questions)

Q1: What makes this sink "heavy duty" compared to standard commercial sinks?

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 restaurant kitchen environments. 316 stainless steel provides superior resistance to salt, harsh cleaning chemicals, and extreme humidity, making it ideal for coastal restaurants or those using aggressive sanitizing agents.

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

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

Q6: Does the sink come with an overflow drain?

A6: An overflow drain is an optional feature. It helps prevent water spillage if the sink is filled too full, making it ideal for busy restaurant kitchens where staff may be multitasking during peak service hours. Contact us to request an overflow drain.

Q7: What installation options are available for restaurant kitchens?

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

Q8: What is the warranty for this restaurant sink?

A8: We provide a 2-year warranty (longer than standard commercial sinks) 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.
