A broken kitchen sink strainer can quickly turn a minor inconvenience into a major plumbing headache. Water backing up, slow drainage, and unpleasant odors are just a few of the issues you might face. Luckily, many strainer problems can be resolved with a bit of DIY know-how and a few simple tools, saving you the expense of calling a plumber. This guide will walk you through diagnosing common strainer issues and providing step-by-step instructions on how to fix a broken kitchen sink strainer.
Identifying the Problem with Your Strainer
Before you start dismantling your sink, it’s crucial to pinpoint the exact nature of the problem. This will help you determine the necessary repair steps and avoid unnecessary work. Here are some common strainer issues:
Leaks: Water leaking from around the strainer basket, the drainpipe connection, or the strainer body itself.
Clogging: Slow drainage or complete blockage due to accumulated food particles and debris.
Damaged Basket: Cracks, dents, or rust in the strainer basket preventing proper sealing.
Loose Connections: Connections between the strainer and the drainpipe becoming loose, leading to leaks.
Tools You’ll Need
Adjustable Pliers or Basin Wrench: For loosening and tightening nuts and connections.
Screwdriver (Phillips and Flathead): For removing and installing screws.
Putty Knife or Scraper: For cleaning old plumber’s putty.
Plumber’s Putty: For creating watertight seals.
Old Towels or Bucket: To catch water and protect your workspace.
New Kitchen Sink Strainer (if replacement is necessary): Be sure to get the correct size and type for your sink.
Gloves (optional but recommended)
Step-by-Step Repair Guide
Once you’ve identified the problem and gathered your tools, follow these steps to fix your broken kitchen sink strainer;
1. Turn off the Water Supply: Locate the shut-off valves under your sink and turn them clockwise to shut off the water supply.
2. Clear the Area: Remove any items stored under the sink to give yourself ample workspace. Place a bucket under the strainer to catch any remaining water.
3. Loosen the Drainpipe Connections: Using your adjustable pliers or basin wrench, carefully loosen the nuts connecting the drainpipe to the strainer. Be prepared for some water to spill out.
4. Remove the Old Strainer:
- If the strainer is held in place by a large nut underneath the sink, loosen it with your pliers or basin wrench.
- If the strainer is held in place by screws, remove them with the appropriate screwdriver.
- Gently push the strainer up from the bottom of the sink and remove it from the top. You might need to use a putty knife to break the seal of the old plumber’s putty.
5. Clean the Sink Opening: Thoroughly clean the sink opening with a putty knife or scraper to remove any old plumber’s putty or debris.
6. Install the New Strainer (if replacing):
- Roll a rope of plumber’s putty and place it around the underside of the strainer flange.
- Insert the strainer into the sink opening from above.
- From below, attach the rubber and cardboard washers, followed by the locking nut.
- Tighten the locking nut securely with your pliers or basin wrench. Be careful not to overtighten.
7. Reconnect the Drainpipe: Reattach the drainpipe to the strainer, tightening the connections securely.
8. Test for Leaks: Turn the water supply back on slowly and check for leaks around the strainer and drainpipe connections. If you find any leaks, tighten the connections further. If the leak persists, you may need to disassemble the connection and apply fresh plumber’s putty or Teflon tape.
Addressing a leaky or clogged sink strainer promptly can prevent more significant plumbing issues and maintain a functional kitchen. Regularly cleaning your strainer will also extend its lifespan and reduce the likelihood of future problems.
