Why Is My Basement Flooding? Common Plumbing Causes in Orillia
July 18, 2025
Basement flooding is a major issue for many Orillia homeowners, especially in spring when snow melts or after heavy rains.
Common causes include sump pump failure, clogged weeping tiles, poor grading around the foundation, or sewer backups.
If your sump pump is over 10 years old or you’ve never had it inspected, it might be time.
We also recommend installing a battery backup system in case of power outages.

They’re great for small homes and cottages around the lake where space is limited.
They also pose a risk to pets, kids, and the environment. Instead, try a plunger or natural alternatives like baking soda and vinegar.
Orillia has fairly hard water, which means sediment builds up at the bottom of your water heater tank over time.
If your sink or tub is draining slowly, it’s likely a build-up of grease, soap, hair, or food waste. Orillia’s older drainage systems are more prone to clogs, especially in homes with mature trees (tree roots love pipes!). DIY drain cleaners can sometimes help, but they often push the clog further down or damage your pipes. If you’ve tried a plunger or baking soda and vinegar with no luck, it’s time to bring in a pro. Our drain cleaning tools at Pro Plumbing Orillia can clear out even the toughest blockages and keep your water flowing freely. Here's a video that may help:
Yes, frozen pipes are a frequent issue during Orillia’s cold winters. When water inside your pipes freezes, it expands and can cause the pipe to burst—leading to costly water damage. To prevent this, make sure your pipes are properly insulated, especially those near exterior walls or in unheated areas like basements and garages. Keep cabinet doors open during cold snaps to let warm air in, and let a small trickle of water run overnight to keep things moving. If your pipes are frozen, don’t use a torch. Call the experts at Pro Plumbing Orillia . We’ll safely thaw your pipes and check for any hidden damage. Here's a video with more info:

Why Does My Toilet Keep Running?” — Orillia Plumber Explains
While Canadian winters offer stunning scenery, they can also put your home’s plumbing at risk. When the temperature falls, water in the pipes can freeze and expand, which may result in cracking or bursting. These plumbing issues often result in expensive repairs and major inconvenience. Fortunately, you can prevent most cold-weather plumbing problems by taking proactive steps before the snow falls. This guide shares practical tips to help homeowners avoid common winter plumbing disasters. From pipe insulation to sump pump maintenance, here’s how to keep your plumbing system running smoothly all season long. 1. Wrap and Protect Exposed Pipes Insulating exposed pipes is one of the most effective strategies to avoid freezing or bursting. Plumbing located in unheated spots like basements, garages, attics, or crawl spaces is particularly at risk during cold weather. Pipe insulation sleeves, heat tape, or foam covers are simple tools that go a long way in protecting your plumbing. Pay special attention to pipes situated along outside walls or in areas prone to drafts. Preventing even one pipe from freezing could save you thousands in emergency repair costs. 2. Shut Off and Drain Outdoor Fixtures Your garden hose and outdoor taps may seem harmless, but they can create major problems in winter. If water remains in exterior faucets or hose bibs, it can freeze and cause interior pipes to rupture. Make sure to disconnect garden hoses ahead of the first frost and empty any leftover water from outdoor taps. If your home has a shutoff valve for external plumbing, turn it off and open the tap to let out any remaining water. Installing frost-free faucets is a smart long-term solution that adds protection for years to come. 3. Check and Test Your Sump Pump Your sump pump protects your basement from flooding due to melting snow or heavy winter rain. To ensure it’s working properly, test it before winter hits. Pour a bucket of water into the sump pit and verify that the pump activates and drains the water quickly. Also, examine the discharge line to confirm it's not blocked or frozen, and that it directs water away from your home. Using a battery backup system is a smart choice, particularly in regions where power outages are common. 4. Seal Gaps Around Pipes and Openings Cold air seeping in through cracks near pipes can cause them to freeze, even if the pipe itself is indoors. Use caulking or spray foam to close up any gaps or cracks in areas like the basement, garage, or utility room. This not only helps safeguard your plumbing from freezing but also boosts energy efficiency, potentially lowering your heating costs. 5. Familiarize Yourself with the Main Water Shutoff Valve If a pipe bursts, quickly shutting off your home's main water supply can greatly minimize the damage. This valve is generally located close to the water meter, often in a basement or utility room. Ensure every adult in your home knows its location and how to use it. In an emergency, turning off the water promptly could make the difference between a small inconvenience and a flooded home. 6. Call Local Plumbers for a Winter Inspection While DIY efforts are helpful, having your plumbing system professionally inspected before winter provides peace of mind. Local plumbers understand regional challenges and can identify issues you might miss like slow drains, worn-out water heaters, or ageing sump pumps. Scheduling a yearly plumbing checkup is a minor expense that can help you avoid major issues in the future. Many companies offer winterization services that include pipe wrapping, leak detection, and outdoor system checks. 7. Flush Your Water Heater With the arrival of winter, your water heater will have to work harder than usual. Flushing the tank helps clear out sediment that builds up over time, which improves efficiency and extends the life of the unit. Make sure the water heater is set to the appropriate temperature—usually around 55°C—to balance comfort, safety, and energy use. If your unit is over 10 years old or shows signs of corrosion, consider consulting a plumber about replacement options before winter sets in. 8. Install Smart Leak Detectors Technology can help homeowners avoid winter plumbing disasters. Leak detection devices are relatively affordable and easy to install near water heaters, sinks, toilets, or sump pumps. These devices alert you via smartphone if a leak is detected. Certain high-tech systems are capable of automatically turning off the water supply, providing extra peace of mind when you're not home. Whether you're on a trip or just at the office, it's comforting to know your property is being looked after. 9. Keep Heat Circulating in the Home Even when you're away, maintain a minimum indoor temperature of at least 12°C to prevent freezing. Keep the cupboard doors beneath sinks open to let warm air move around the pipes, particularly those located along outside walls. If you’ll be away for a long time, consider having a neighbour check in on your house occasionally. Catching a frozen pipe early can make a big difference in preventing a costly repair. Winter brings plenty of challenges, but a burst pipe doesn’t have to be one of them. Implementing a few simple precautions now can help you steer clear of serious plumbing issues in the future. From sealing cracks to checking your sump pump and scheduling a visit from experienced local plumbers, the steps you take today will protect your home all winter long. By preparing your plumbing system for freezing temperatures, you’re not only avoiding emergencies you’re preserving the comfort, safety, and value of your home.
