FAQs
How long does this project typically take for a beginner, and what's the difficulty level?
This is a beginner-level plumbing project, often taking 1-2 hours for someone new to DIY. Most of the time is spent on prep, cleaning the sink opening, and ensuring a watertight seal, so take your time and follow the steps carefully.
Do I really need plumber's putty, or can I use silicone sealant for the seal?
Plumber's putty is highly recommended for basket strainers as it creates a flexible, watertight seal that's easier to remove later if future repairs are needed. While silicone can seal, it creates a much more permanent bond and can be very difficult to clean off or remove if you ever need to replace the strainer again.
What should I do if my old basket strainer is stuck and won't unscrew from the sink?
If your old strainer is seized, apply KROIL Penetrating Oil to the threads and any rusted connections under the sink. Let it soak for 15-30 minutes. Use your Channellock pliers to get maximum leverage, and sometimes a gentle tap with a hammer on the wrench can help break it free, but avoid excessive force.
What are the most common reasons for leaks after installing a new basket strainer?
Leaks usually occur from either insufficient plumber's putty or improper tightening. Ensure you apply a generous, even bead of putty under the strainer flange and that the locknut is securely tightened by hand, then a quarter to half turn with pliers, without overtightening which can damage the sink.
