Frequently Asked Questions - KA21SS CDA

What are the exact dimensions of the CDA KA21SS sink?

The sink bowl measures approximately 600 mm x 450 mm x 200 mm (length x width x depth). The required cut-out size is about 580 mm x 430 mm. Always verify with the actual product before installation.

Which faucet is compatible with this sink?

The sink is compatible with any standard deck mount faucet. The faucet hole spacing is typically 8 inches (203 mm) for a widespread faucet. Alternatively, a single-hole faucet can be used if the deck is pre-drilled accordingly.

How do I install the CDA KA21SS undermount sink?

Installation should be performed by a qualified professional. The sink is fixed to the underside of the countertop using provided mounting clips and silicone sealant. Ensure the cut-out is accurate and the countertop material is suitable for undermount installation.

Can I use bleach or abrasive cleaners on the sink?

No, avoid bleach, chlorine, and abrasive cleaners as they can damage the stainless steel finish. Use mild dish soap and a soft sponge. For hard water stains, use a vinegar solution.

Does the sink come with a drain assembly?

Yes, the sink includes a drain strainer and mounting clips. However, the pop-up drain or garbage disposal may be purchased separately depending on your plumbing needs.

How do I remove scratches from the stainless steel surface?

Minor scratches can be buffed out using a non-abrasive stainless steel cleaner and a soft cloth, always following the grain. For deeper scratches, contact CDA customer service for repair recommendations.

Is the sink soundproofed?

Yes, the sink is equipped with sound-deadening pads to reduce noise from water flow and dish clatter.

What is the warranty period for the CDA KA21SS sink?

The sink comes with a 10-year warranty against manufacturing defects. This covers issues like cracks or faulty welding. Normal wear and tear, scratches, or stains are not covered.

Can I use a garbage disposal unit with this sink?

Yes, the sink is compatible with standard garbage disposal units. Ensure the disposal mounting flange fits the 3.5 inch drain opening. Reinforcement may be needed for heavy disposals.

How do I clean hard water stains from the sink?

Mix equal parts water and white vinegar, apply with a soft cloth, let sit for a few minutes, then rinse thoroughly. Dry the sink with a clean cloth to prevent water spots.

Taking Care of your Sink

Your CDA sink is manufactured using material developed specifically to withstand the rigours of everyday kitchen use. However, we advise you to follow these precautions to keep the sink in pristine condition:

• Do not use a plastic washing-up bowl in the sink as grit and other particles may become embedded in the bowl and scratch or erode the sink surface. CDA specifically recommend the use of wire sink-baskets and drainer-racks to help protect your sink. Take care to not cut the plastic coating on these accessories with sharp cutlery or the edges of pans, etc.
• Do not use neat bleach or other harsh cleaning agents on the metal sink waste as this may cause tarnishing. This is especially important if the waste is of the brass/brass finish type.
• Avoid dropping heavy or sharp objects into the sink as they may scratch or damage the surface.
• The surface of the sink can be affected by certain chemicals e.g. neat bleach, nail polish remover, paint stripper, solvents, brush cleaner and insecticides. If any of these substances come into contact with the sink, wipe off immediately with a dry cloth, wash with mild detergent and rinse with water.
• Do not use abrasive liquids, powders or steel pads to clean the sink as they will damage the sink surface and make it more susceptible to staining. The sink may be cleaned with a dilute bleach solution.
• In hard-water areas, a limescale deposit may build up on the sink. The limescale may become stained by coloured foods such as coffee or red wine. If this occurs, we recommend use of a mild limescale remover.
• Particularly stubborn organic stains can be removed effectively by soaking the sink in a biological washing-powder solution, dishwasher powder solution or diluted bleach.
• If the sink comes into contact with acidic materials, rinse immediately with plenty of water and wipe with a soft dry cloth.
• Do not leave rusty objects in contact with the sink. Rust can cause staining, cracking or even permanent damage to the sink surface.
• To avoid staining of the surface do not leave food or other materials with corrosive properties such as juices, salt, vinegar, mustard etc. on the sink for a long time.
• After using the sink, rinse it clean with warm soapy water and rinse with clean water before wiping dry.
  • During installation, protect from scratches, scuffs and other damage.
  • Do not overtighten or strain plumbing fittings.
• The moulding and edges of the sink must be absolutely level so water flows off the drainer.

Important Information about your Sink

Although stainless steel sinks are built to last a lifetime, consumers are almost always concerned about three specific natural occurrences that may appear on their new sink.

Scratching

Stainless steel is NOT scratch resistant and is susceptible to scratching through normal wear. Scratches are most prevalent when the sink is brand new but through continual use, scratches will become more uniform and less apparent over time.

Rust spots

Rust coloured spots which may appear on a new sink do not indicate that the sink itself is rusting. The appearance of these spots is attributed to external factors most commonly related to ferrous particles which come through the water supply following the installation of new pipe work. These particles are not visible to the eye until they start to rust and are likely to appear in the first six to twelve months of use. Cleaning may remove the rust stain but not eliminate the cause. It is however important to avoid the use of steel wool which will exacerbate the problem.

Water staining

Limescale deposits and ‘rainbow’ discolouration which may appear on a stainless steel surface are solely due to environmental factors and not inherent faults within the product. Through continuous use and regular cleaning, these effects will disappear.
