Living in Toronto means enjoying the charm of established neighbourhoods, beautiful homes and four distinct seasons. But it also means your home’s plumbing system can face unique challenges, from freezing winter temperatures to aging infrastructure in older homes. At The Great Plumbing Co, we hear the same core questions time and time again. So, we’ve rounded up the top 5 plumbing questions from Toronto homeowners and we’re giving you the expert answers you need to keep your home running smoothly.
1. Why Do My Pipes Make Banging Noises? This is one of the most common (and alarming) questions we get. That loud banging or knocking sound in your pipes is often caused by a phenomenon called “water hammer.” It happens when a valve suddenly shuts off and the momentum of the water hits a closed valve or pipe elbow. In older Toronto homes, this is often due to worn or absent air chambers that are meant to absorb the shock. Left unchecked, water hammer can loosen pipe joints or even cause leaks.
Solution: A licensed plumber can install a water hammer arrestor or re-pressurize the air chambers. Regular plumbing inspections help catch these early.
2. Why Is My Water Pressure So Low?
Toronto’s municipal water supply typically provides strong water pressure. So when you experience a noticeable drop, it’s usually an issue within your home. Common causes include:
* Mineral buildup inside aging pipes
* Partially closed shut-off valves
* Leaky pipes reducing pressure
* Clogged faucet aerators or shower-heads
If your home was built before the 1970s, you may still have galvanized steel pipes, which corrode from the inside over time and restrict water flow.
Pro Tip: Try removing the aerator from a faucet and cleaning out any debris. If that doesn’t help, it may be time for a more detailed plumbing inspection to locate the source.
3. How Can I Tell If I Have a Hidden Leak? Not all leaks are visible. In fact, some of the most damaging plumbing issues happen behind walls or under flooring causing rot, mold or major water damage before you ever see a puddle.
Warning signs of a hidden leak include:
- Unexplained increases in your water bill
- The sound of running water when everything is off
- Mouldy smells or damp spots
- Staining on ceilings or walls
Toronto’s variable weather (freeze-thaw cycles) can worsen small cracks in pipes, especially in basements and crawl spaces.
Solution: If you suspect a hidden leak, don’t wait. The Great Plumbing Co uses non-invasive leak detection tools like thermal imaging and acoustic sensors to locate leaks with minimal disruption.
4. Why Do I Run Out of Hot Water So Quickly? This is usually tied to your water heater’s capacity or performance. Older or undersized water heaters can’t keep up with household demand, especially during colder months when incoming water is cooler. Sediment buildup in the tank is another common cause in Toronto, where hard water is an issue.
Pro Tip: Flushing your water heater annually can improve efficiency. Consider upgrading to a tankless system for continuous hot water.
5. Should I Be Worried About Tree Roots in My Sewer Line?
Yes, especially in older Toronto neighbourhoods with mature trees and aging clay or cast iron pipes. Tree roots are drawn to the moisture and nutrients in sewer lines and can break into pipes causing: Blockages and backups/slow draining sinks, tubs and toilets and Foul odours in your home.
Solution: Schedule a video camera inspection to check for root intrusion. Catching this early can prevent costly damage and messy repairs.
