Replacing a sink strainer is easier than you think! First, gather your tools: a new strainer, plumber’s putty, a wrench, and maybe a bucket. Disconnect the old strainer, clean the sink opening, and apply plumber’s putty to the new strainer. Insert the new strainer, tighten it up from underneath, and remove any extra putty. Now you have a leak-free sink!

Ready to say goodbye to that old, yucky strainer? In this guide, we’ll walk you through each step, from gathering your supplies to tightening that final nut. Let’s get started!
What You’ll Need
Before we dive in, let’s make sure you have everything you need. Here’s a quick checklist of tools and materials:
- New Sink Strainer: Choose one that fits your sink’s drain size.
- Plumber’s Putty: This creates a watertight seal.
- Adjustable Wrench: For loosening and tightening nuts.
- Bucket or Bowl: To catch any water.
- Putty Knife or Scraper: To remove old putty.
- Screwdriver: Needed for some strainer models.
- Rag or Sponge: For cleaning.
- Gloves: To keep your hands clean.
Step-by-Step Guide to Replacing a Sink Strainer
Step 1: Prepare the Area
First things first, clear out the space under your sink. Remove any items that might get in the way. Place a bucket or bowl under the sink strainer to catch any water that might be left in the pipes.
Step 2: Disconnect the Old Strainer
Now, let’s get that old strainer out. This part can be a bit messy, so have your gloves on and your rag ready.
- Loosen the Nut: Use your adjustable wrench to loosen the nut that holds the strainer in place from underneath the sink.
- Remove the Washers and Gasket: As you loosen the nut, you’ll see washers and a rubber gasket. Keep these aside; you won’t need them for the new strainer.
- Push Out the Old Strainer: Once everything is loose, push the old strainer up from underneath the sink. It might be stuck, so wiggle it gently.
Step 3: Clean the Sink Opening
With the old strainer out, it’s time to clean the sink opening. This step is crucial for a good seal with the new strainer.
- Scrape Away Old Putty: Use your putty knife or scraper to remove any old plumber’s putty or residue around the sink opening.
- Clean the Surface: Wipe the area clean with a rag or sponge. Make sure the surface is dry before moving on.
Step 4: Apply Plumber’s Putty
Plumber’s putty is what creates a watertight seal between the strainer and the sink. Here’s how to apply it:
- Roll the Putty: Take a roll of plumber’s putty and roll it into a rope about ½ inch thick.
- Apply Around the Opening: Place the putty rope around the sink opening where the strainer will sit. Make sure it’s an even layer.
Step 5: Install the New Strainer
Now for the exciting part – installing the new strainer!
- Insert the Strainer: Place the new strainer into the sink opening, pressing down gently. The putty should squish out a bit.
- Remove Excess Putty: Use your finger or a putty knife to remove any excess putty that squeezed out. This makes for a cleaner look and a better seal.
Step 6: Tighten the Strainer
Head back under the sink to tighten everything up.
- Attach the Washers and Nut: Place the rubber gasket and washers (that came with the new strainer) onto the strainer’s tailpiece from underneath the sink.
- Tighten the Nut: Use your adjustable wrench to tighten the nut. Don’t overtighten it, just make sure it’s snug.
Step 7: Connect the Plumbing
Almost there! Now, reconnect the drainpipe to the new strainer.
- Reattach the Drainpipe: Connect the drainpipe to the strainer’s tailpiece. Tighten any connections with your adjustable wrench.
Step 8: Test for Leaks
The final step is to test your work. Run water into the sink and check for any leaks around the strainer and drainpipe.
- Check for Leaks: Look under the sink while the water is running. If you see any drips, tighten the connections a bit more.
- Dry Everything: Once you’re sure there are no leaks, dry everything off with a rag.
Troubleshooting Common Issues
Sometimes, things don’t go exactly as planned. Here are a few common issues and how to fix them:
- Leak Under the Sink: If you see a leak under the sink, it usually means the connections aren’t tight enough. Tighten the nuts with your adjustable wrench.
- Strainer Won’t Sit Flush: If the strainer isn’t sitting flush with the sink, make sure you’ve used enough plumber’s putty. You might need to remove the strainer and add more putty.
- Drainpipe Doesn’t Align: If the drainpipe doesn’t align with the strainer’s tailpiece, you might need to adjust the pipes slightly. Loosen the connections and try again.
Choosing the Right Sink Strainer
Picking the right sink strainer is key to a successful replacement. Here’s a quick guide to different types and features:
Types of Sink Strainers
| Type | Description | Pros | Cons |
|---|---|---|---|
| Basket Strainer | Has a removable basket to catch food particles. | Easy to clean, prevents clogs. | Can be more expensive. |
| Post Strainer | A simple strainer with a post to stop large items. | Inexpensive, easy to install. | Less effective at catching small particles. |
| Disposer Strainer | Designed for sinks with garbage disposals. | Durable, fits disposals perfectly. | Only works with garbage disposals. |
Materials
- Stainless Steel: Rust-resistant and durable.
- Brass: Classic look, but can tarnish.
- Plastic: Inexpensive, but less durable.
Safety Tips
While replacing a sink strainer is a simple project, it’s important to stay safe:
- Turn Off the Water: Before you start, turn off the water supply to the sink. This prevents any unexpected floods.
- Wear Gloves: Protect your hands from dirt and grime by wearing gloves.
- Don’t Overtighten: Overtightening nuts can damage the strainer or pipes. Tighten them until they’re snug, but not too tight.
- Dispose of Old Parts Properly: Throw away old parts and plumber’s putty in a sealed bag to prevent any mess.
Cost Considerations
Replacing a sink strainer is a budget-friendly project. Here’s a breakdown of the costs:

Compared to hiring a plumber, which can cost $100 or more, doing it yourself can save you a lot of money.
When to Call a Professional
While most sink strainer replacements are straightforward, there are times when it’s best to call a professional plumber:
- Extensive Plumbing Issues: If you notice any major plumbing problems, like corroded pipes or leaks in the wall, it’s best to consult a pro.

FAQ: Replacing a Sink Strainer
Q: How do I know what size sink strainer to buy?
A: Measure the diameter of your sink’s drain opening. Most standard sinks use a 3.5-inch strainer, but it’s always best to measure to be sure.
Q: Can I use silicone caulk instead of plumber’s putty?
A: While silicone caulk can create a seal, plumber’s putty is generally recommended for sink strainers. It’s easier to work with and won’t dry out or crack over time. Plus, it’s designed for this specific purpose.
Q: How do I remove a really stuck sink strainer?
A: If the strainer is really stuck, try using a penetrating oil like WD-40 to loosen the nut. Let it sit for a few minutes, then try again. You might also need a longer wrench for more leverage.
Q: Do I need to turn off the water before replacing the strainer?
A: Yes, it’s always a good idea to turn off the water supply to the sink before starting any plumbing work. This prevents any unexpected leaks or floods.
Q: What if I overtighten the nut under the sink?
A: Overtightening the nut can damage the strainer or the pipes. If you think you’ve overtightened it, loosen it slightly. The goal is to make it snug, not super tight.
Q: How often should I replace my sink strainer?
A: A good quality sink strainer can last for many years. Replace it when it becomes damaged, rusty, or starts to leak.
Q: What do I do with the old plumber’s putty?
A: Dispose of the old plumber’s putty in a sealed bag. This prevents it from sticking to things or creating a mess in your trash can.
