Setup and Installation
This basket strainer is designed for straightforward installation into standard 3.5-inch sink drain openings. Professional plumbing installation is recommended to ensure proper sealing and function.
Required Tools (Not Included):
- Plumber's putty or silicone sealant
- Adjustable wrench or basin wrench
- Screwdriver (if applicable for specific drain types)
Installation Steps:
- Prepare the Sink Opening: Ensure the sink drain opening is clean and free of any old sealant or debris.
- Apply Sealant: Apply a bead of plumber's putty or silicone sealant around the underside rim of the strainer flange that will sit in the sink opening.
- Position the Strainer: Insert the strainer body through the sink opening from the top. Press firmly to create a seal with the putty/sealant.
- Install Gasket and Nut: From underneath the sink, slide the rubber gasket (if provided) onto the strainer body, followed by the friction washer and the large locknut.
- Tighten Securely: Hand-tighten the locknut, then use an adjustable wrench or basin wrench to tighten it further. Do not overtighten, as this can damage the sink or strainer.
- Connect to Plumbing: Attach the tailpiece of your plumbing system to the bottom of the strainer body, ensuring all connections are secure and leak-free.
- Test for Leaks: Fill the sink with water and check for any leaks around the strainer and plumbing connections. Tighten as necessary.

Operating Instructions
The BLANCO Metal Basket Strainer features a simple open/close design for effective use.
- For Draining: To allow water to drain freely, ensure the basket is in the open position. This typically involves lifting the center post slightly or rotating the basket to align openings.
- For Sealing: To create a tight protective seal and hold water in the sink, press the basket down firmly into the drain opening. The design is intended to create a secure seal.
- Debris Collection: The basket effectively collects food particles and other debris, preventing them from entering your drain pipes.
Maintenance and Care
Regular cleaning and proper care will help maintain the appearance and functionality of your BLANCO Metal Basket Strainer.
- Daily Cleaning: Remove the basket regularly to empty collected debris. Rinse the basket and the strainer body with warm water.
- Gentle Cleaning: For general cleaning, use a soft cloth or sponge with mild dish soap and warm water. Wipe down the strainer and rinse thoroughly.
- Avoid Abrasives: Do not use abrasive cleaners, scouring pads, or harsh chemical detergents, as these can damage the Coal Black finish.
- Protect the Finish: While durable, the color-coordinated finish can be susceptible to chipping or scratching if exposed to sharp metal objects or harsh impacts. Exercise care when placing utensils or heavy pots in the sink.
- Periodic Inspection: Periodically check the strainer for any signs of wear or damage. Ensure the seal remains effective.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaks around the strainer. | Improper installation, loose connections, or damaged sealant/gasket. | Check the locknut underneath the sink and tighten if loose. Inspect the plumber's putty or silicone seal; reapply if necessary. Ensure gaskets are correctly seated. |
| Strainer does not seal properly. | Debris under the basket, worn gasket, or improper seating. | Remove the basket and clean any debris from the drain opening and the basket's sealing surface. Ensure the basket is pressed down firmly and evenly. |
| Slow drainage. | Basket clogged with debris, or plumbing blockage. | Remove and thoroughly clean the basket. If drainage remains slow, the issue may be further down the plumbing system. |
| Finish chipping or scratching. | Contact with abrasive materials, sharp objects, or harsh cleaning agents. | Avoid using abrasive cleaners or scrubbing pads. Be careful when placing metal utensils or heavy items in the sink to prevent direct impact on the strainer's finish. |
