Tips

  • If the nut is difficult to remove, use a hacksaw or cutting wheel.
  • When tightening the brass nut, hold the threaded part with one hand to prevent spinning the basket.

Common Mistakes to Avoid

1. Over-tightening the basket strainer

Reason: Over-tightening can strip the threads on the sink flange or the basket strainer itself, making it difficult or impossible to remove later.
Solution: Tighten the basket strainer firmly but gently, using your hand as much as possible before resorting to pliers.

2. Ignoring sealant or using the wrong type

Reason: Improper sealing can lead to leaks and water damage. Using the wrong type of sealant may not be durable enough for the wet environment.
Solution: Apply a bead of plumber's putty or silicone sealant around the sink flange before installing the basket strainer.

FAQs

What if my new basket strainer doesn't fit my sink?
Sink basket strainers come in various sizes and styles. Before purchasing a replacement, carefully measure your existing basket and sink drain opening. Ensure the new strainer's dimensions match. If it's slightly off, you may need to purchase a different size or style compatible with your sink. Some sinks require specific types of strainers; check your sink's manufacturer information if you're unsure.
