10 Common Plumbing Problems Homeowners in Toronto Face

If you live in Toronto, plumbing problems are almost guaranteed at some point. One day, everything works fine. Next, there’s a drip or a weird smell from the basement. It doesn’t matter if your home is a shiny condo in North York or an older brick house in Cabbagetown. Plumbing issues just happen.

The key is spotting them early before they cause damage, cost too much, or become a real headache. Knowing what to look for and when to call a plumber can save you a lot of stress and money.

1. Leaky Faucets

Those tiny drips. They seem harmless. At first, you barely notice them. Weeks later, your water bill spikes, and maybe the cabinet under the sink is damp. Kitchen and bathroom taps are the usual suspects. The causes? Worn-out washers, loose parts, or corroded old taps. Sometimes replacing a washer or seal fixes it fast. Sometimes the whole tap is so old that swapping it out is easier. Ignoring it will eventually damage counters or cabinets; honestly, the noise drives most people crazy before the damage does.

2. Clogged Drains

Clogs are everywhere, and they don’t wait for convenient times. Bathroom drains fill up with hair, and kitchens with grease and food particles. At first, the water drains slowly. You shrug. Then it backs up, smells bad, and suddenly plungers don’t help. Older Toronto homes with narrow pipes? Forget about DIY fixes most of the time. Left unchecked, slow drains become bigger problems, including pipe corrosion or water pooling in unwanted places. Regularly cleaning and being mindful of what goes down the drain is a small effort that saves a lot of hassle.

3. Running Toilets

The sound of a toilet constantly running is worse than you remember. It’s annoying. It wastes water. A running toilet is usually caused by a faulty flapper, float, or fill valve. Sometimes it’s just the age of the bathroom itself. Fixing it can be a quick job for a plumber, but ignoring it can add hundreds to your yearly water bill. And yes, the trickle never stops until it’s addressed. It’s one of those minor problems that quietly becomes expensive if you don’t act.

4. Low Water Pressure

Ever try to shower and feel like you’re barely getting wet? Low water pressure is more common than people think in Toronto. The causes vary: mineral buildup in pipes, a failing pressure regulator, or sometimes issues with the municipal supply. Some homes only have it in certain faucets, while others throughout the house. It’s frustrating because it affects everyday tasks like washing dishes or laundry. It is key to figuring out whether the problem is localized or house-wide before trying to fix it.

5. Water Heater Problems

Nothing feels worse than stepping into a freezing shower in February. Water heaters can encounter problems like insufficient hot water, strange noises, leaks, or thermostat failures. Sediment buildup in the tank reduces efficiency over time. Flushing the system helps in some cases. Other times, parts or even the whole unit need replacing. Annual maintenance is underrated but keeps showers warm and prevents surprise bills. For Toronto winters, it’s worth doing.

6. Pipe Leaks

Leaks are sneaky, especially when hidden behind walls or under floors. Older homes in the GTA are particularly vulnerable, especially with winter freeze-thaw cycles stressing the pipes. Signs include water stains, damp patches, or mysteriously high water bills. Small leaks can be patched, but bigger ones often require replacing pipe sections. Ignoring leaks is risky. Mould and wood rot can start before you notice the leak, which gets expensive fast. Catch them early.

7. Sewer Line Problems

Sewer line issues aren’t everyday problems, but when they happen, they are messy. Roots from trees, pipe corrosion, and debris can block lines, causing backups in multiple parts of your home. You might notice slow drains, gurgling sounds, or foul smells. Resolving this usually requires a plumber with cameras or hydro-jetting equipment. In older Toronto neighbourhoods like The Beaches or Rosedale, sewer line problems often happen because of aging infrastructure. Acting fast prevents a bigger, more expensive mess.

8. Frozen Pipes

Winter in Toronto is brutal, and frozen pipes are a real threat. When water freezes, it expands, and pipes can burst. Basements, crawl spaces, and garages are especially at risk. Insulating exposed pipes and maintaining steady indoor temperatures helps prevent freezing. If a pipe does freeze, turn off the water and slowly thaw it with warm air or towels. Burst pipes are much worse than frozen ones—they cause water damage that can take weeks to repair. Prevention really is easier than repair here.

9. Sump Pump Failure

If your home is in a low-lying area, near Lake Ontario or along the Humber, sump pumps are essential to prevent basement flooding. Failures happen because of power outages, mechanical issues, or clogs. Regular checks of the float switch and cleaning debris from the pit go a long way. Spring thaw or heavy rainstorms can cause a flooded basement if the pump fails, so don’t wait for an emergency to realize it’s broken. Regular maintenance avoids big headaches.

10. Water Quality Problems

Water quality often goes unnoticed until it’s too late. Hard water, minerals, or sediment buildup can damage pipes, appliances, and fixtures over time. You might notice stains, cloudy water, or a weird taste. Installing water softeners or filtration systems can help protect plumbing and improve water quality. In Toronto, older homes with original pipes are particularly vulnerable. Regular inspections and system updates ensure clean water and less stress on the pipes.
