Take a small amount of plumber's putty and roll it into a rope shape. Apply the putty rope to the underside of the new strainer's flange. Press the strainer firmly into the sink hole from the top. From underneath, install the rubber gasket, fiber washer, and the large metal locknut. Use a sink installer tool to hold the strainer from the inside while you tighten the locknut from below with pliers to ensure it's secure.

FAQs
How difficult is installing a kitchen sink basket strainer for a beginner, and how long should I expect it to take?
This project is considered beginner-friendly, but patience is key, especially with removing an old, stubborn strainer. While estimated at 3 hours, allow extra time, perhaps up to 4-5 hours, if you encounter unexpected issues or if the old components are corroded. Having the right tools ready will significantly streamline the process.
What's the purpose of plumber's putty, and is there an alternative I can use for sealing?
Plumber's putty creates a watertight seal between the new strainer's flange and the sink opening, preventing leaks. While some people use silicone sealant as an alternative, plumber's putty is generally preferred for this application because it remains pliable, making future disassembly and repairs much easier. Ensure a generous, even bead for a reliable seal.
My old strainer is really stuck; what's the best way to remove it without damaging the sink?
If the old strainer's locknut is corroded and won't budge, try applying penetrating oil and letting it soak. You can also use a basin wrench or a large pair of Channellock pliers for leverage. If it's still stuck, insert a screwdriver into the crossbars of the strainer from above and tap it gently with a hammer from below to loosen the nut. Avoid excessive force to protect your sink.
Do I need all the specific tools listed, especially the locknut wrench, or can I get by with basic tools?
While you might manage with large channel-lock pliers, a dedicated locknut wrench (like the Husky Lock Nut Wrench 16PL0133) or a basin wrench is highly recommended. These tools provide better grip and leverage in tight spaces, making it much easier to properly tighten the locknut and ensure a secure, leak-free seal without overtightening or damaging components.
