Common Questions Covered in the Video
Components of a Basket Strainer
The video explains the typical components, including:

Locknut
Washer Installed First
Under the sink, the rubber washer is typically installed first against the sink, followed by the friction washer and then the locknut.
Purpose of Plumber’s Putty
Plumber’s putty creates a watertight seal between the basket strainer and the sink basin to prevent leaks.
Preparing the Plumber’s Putty
The video demonstrates how to:
Knead the putty until soft
Roll it into a rope
Place it evenly around the sink drain opening
Installing the Washers and Nut
The video shows the correct order for:
Sliding washers onto the strainer body
Tightening the locknut evenly from underneath
Ensuring a Proper Seal
The video explains how tightening the strainer compresses the plumber’s putty, forming a complete seal around the drain opening.
Tools for Tightening the Nut
The video demonstrates tightening methods using:
Adjustable wrench
Channel-lock pliers
Removing Excess Plumber’s Putty
After tightening, excess plumber’s putty should be removed from around the sink opening.
Testing for Leaks
The video shows how to:
Run water in the sink
Check underneath for leaks
