How to Repair a Kitchen Sink While Waiting for a Plumber – Pro Plumbing Thunder Bay
If your kitchen sink is clogged, leaking, or simply not draining, you don’t have to sit idly by while waiting for a professional plumber. As a seasoned plumber at Pro Plumbing Thunder Bay, I’ve seen homeowners panic when their sink suddenly stops working. The good news? There are a few things you can do to mitigate the issue before we arrive. Here’s how you can handle common sink problems safely and effectively.

1. Dealing with a Clogged Kitchen Sink
A clogged sink is one of the most common issues homeowners face. Here’s what you can do to get the water flowing again:
Try Boiling Water First
- Bring a kettle or pot of water to a boil.
- Carefully pour it down the drain in stages.
- Wait a few minutes and see if the water starts draining.
- Repeat if necessary.
Use a Plunger
- If boiling water doesn’t work, grab a sink plunger (not the same one used for toilets!).
- Fill the sink with a few inches of water.
- Position the plunger over the drain and push down firmly, then pull up in a quick motion.
- Repeat several times until the clog loosens.
Baking Soda & Vinegar Method
- Pour half a cup of baking soda down the drain.
- Follow it with one cup of white vinegar.
- Let the mixture fizz for 10–15 minutes.
- Flush with hot water.
2. Fixing a Leaky Pipe Under the Sink
Leaks under the sink can cause water damage fast. Here’s how to stop the water temporarily:
Tighten Loose Connections
- Check where the leak is coming from.
- If it’s at a joint, try tightening the slip nuts with a wrench.
Use Plumber’s Tape or Pipe Putty
- If you find a small leak in a pipe joint, wrap plumber’s tape around the threads.
- For small cracks, apply pipe putty as a temporary fix.
Place a Bucket Under the Leak
- If tightening the connections doesn’t work, place a bucket under the pipe to catch the water until a plumber arrives.
3. Handling a Slow-Draining Sink
If your sink is draining slowly but not fully clogged, try these quick solutions:
Clean the P-Trap
- Place a bucket under the sink to catch water.
- Unscrew the P-trap (the U-shaped pipe under the sink).
- Remove debris and rinse it out before reattaching it.
Use a Drain Snake
- A simple drain snake or wire hanger can help remove debris stuck in the drain.
- Insert it into the drain, twist it, and pull out any gunk blocking the pipe.
4. What NOT to Do While Waiting for a Plumber
- Avoid Chemical Drain Cleaners – These can damage your pipes and make the problem worse.
- Don’t Keep Running Water – If the sink is leaking or clogged, using it can lead to more damage.
- Don’t Ignore a Major Leak – If water is flooding, shut off the water supply immediately.
