4. Installation
This sink strainer is designed for easy installation in standard 3-1/2 inch or 4-inch kitchen sink drain openings. Basic plumbing knowledge and tools are recommended.
Installation Steps:
- Prepare the Drain Opening: Ensure the sink drain opening is clean and free of old sealant or debris.
- Apply Sealant (Optional): While the unit includes washers for sealing, a thin bead of plumber's putty or silicone sealant can be applied around the underside of the strainer flange that sits in the sink opening for an extra watertight seal.
- Position the Strainer: Place the upper part of the strainer into the sink drain opening from above.
- Assemble from Below: From underneath the sink, place the rubber gasket, then the friction washer, and finally thread the brass nut onto the strainer body.
- Tighten Securely: Hand-tighten the brass nut, then use an appropriate tool (such as a large flat-head screwdriver or basin wrench) to tighten it further until snug. Do not overtighten.
- Test for Leaks: Fill the sink with water and check for any leaks around the strainer assembly. Tighten further if necessary.
5. Operation
The Kraus Kitchen Sink Strainer features a simple open-close stopper mechanism for convenient use.
Using the Stopper:
- To Drain Water: Ensure the center post of the strainer basket is in the raised position, allowing water to flow freely through the perforations.
- To Retain Water: Press the center post of the strainer basket down firmly. This will engage the stopper, sealing the drain opening and retaining water in the sink.
- To Remove Strainer Basket: Simply lift the strainer basket out of the drain opening for cleaning or to access the drain.

- Thorough Cleaning: For a more thorough clean, wash the strainer basket and the main body with mild soap and warm water. Use a soft cloth or sponge.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, steel wool, or harsh chemical detergents, as these can damage the ABS plastic finish.

7. Troubleshooting
If you encounter issues with your sink strainer, refer to the following common troubleshooting tips.
Common Issues and Solutions:
- Slow Draining: If water is draining slowly, the strainer basket may be clogged with food particles or debris. Remove the basket and clean it thoroughly.
- Water Leaks Around Strainer: Check the tightness of the brass nut underneath the sink. Ensure that the rubber gasket and friction washer are correctly seated and not damaged. If necessary, disassemble, inspect components, and reassemble, ensuring proper sealing.
- Stopper Not Sealing: If the stopper does not hold water, ensure no debris is preventing it from seating properly. Clean the stopper mechanism and the drain opening. Verify the stopper is fully pressed down.
