Plumbing problems can happen at any time, especially in Toronto where seasonal changes, aging infrastructure, and heavy usage put extra stress on plumbing systems. Knowing the most common plumbing issues—and how to handle them—can save you time, money, and stress.
In this guide, we’ll cover the top 10 plumbing problems in Toronto homes and when it’s time to call a professional plumber.
1. Leaky Faucets
A dripping faucet may seem minor, but it can waste hundreds of liters of water over time.
Common Causes:
- Worn-out washers
- Corroded valve seats
- Loose parts
Quick Fix:
Tightening or replacing small components may solve the issue, but persistent leaks often need professional repair.

2. Clogged Drains
Clogged drains are one of the most frequent plumbing problems in both residential and commercial properties.
Common Causes:
- Hair buildup
- Grease and food waste
- Soap residue
Tip:
Avoid chemical drain cleaners—they can damage your pipes. Instead, use a plunger or call for professional drain cleaning.

3. Running Toilets
A running toilet can waste a significant amount of water and increase your utility bills.
Possible Issues:
- Faulty flapper
- Fill valve problems
- Float imbalance
Solution:
Simple replacements may fix it, but if the problem continues, it’s best to get expert help.

4. Low Water Pressure
Low water pressure can make everyday tasks frustrating.
Common Causes:
- Pipe corrosion
- Hidden leaks
- Mineral buildup
When to Call a Pro:
If the issue affects multiple fixtures, it could be a serious plumbing system problem.

5. Water Heater Issues
No hot water? That’s a big problem—especially during Toronto winters.
Common Problems:
- Sediment buildup
- Faulty thermostat
- Aging unit
Tip:
Regular maintenance can extend the life of your water heater.

6. Burst or Frozen Pipes
Frozen pipes are a major concern in cold climates like Toronto.
Warning Signs:
- No water flow
- Frost on pipes
- Strange noises
Important:
Turn off the main water supply immediately and call a professional plumber.

7. Sewer Line Problems
Sewer issues can cause serious damage and health hazards.
Signs:
- Bad odors

- Backups
Solution:
Professional inspection (camera inspection) is usually required.

8. Sump Pump Failure
Sump pumps protect your basement from flooding.
Common Issues:
- Power failure
- Mechanical failure

Tip:
Test your sump pump regularly—especially before heavy rain seasons.

9. Dripping or Leaking Pipes
Hidden leaks can cause structural damage and mold.
Check for:
- Water stains

- Higher water bills
Action:
Leak detection services can locate hidden issues quickly.

10. Backed-Up Drains
Backups are more serious than simple clogs.
Causes:

Solution:
Professional drain cleaning or hydro jetting is often required.
