Atmospheric rivers are hitting Victoria and Sooke more often (and harder) than ever. These intense rain events are no longer rare, and the impact on local homes is growing. Canada’s Changing Climate Report (led by ECCC / Government of Canada) discusses observed and projected changes in precipitation and extremes, including increases in extreme precipitation events.
At Homewise Plumbing, we’ve seen firsthand how overwhelmed drainage systems, failed sump pumps, and neglected perimeter drains can quickly turn a storm into a plumbing emergency. The good news? Most of it is preventable.
Here’s how to make sure your home’s plumbing and drainage are ready before the next big storm rolls in.
What Is an Atmospheric River, and Why Should You Be Concerned?
An atmospheric river is a narrow band of concentrated moisture in the atmosphere that delivers intense rainfall over short periods. These events are a growing concern for homeowners throughout southern B.C., including the Capital Regional District, as they can lead to:
- Overwhelmed perimeter drains
- Basement flooding
- Foundation leaks
- Sewer backups
During the 2021 atmospheric river, Victoria and surrounding communities saw record rainfall. In low-lying neighbourhoods like James Bay, Esquimalt, and Langford, many homes experienced drainage failures and water damage.
How Extreme Weather Events Have Affected Local Plumbing
At Homewise, we were on the front lines helping local residents deal with:
- Clogged or broken perimeter drain systems
- Failed or undersized sump pumps
- Sewage backups due to inadequate backflow prevention
- Leaking foundations from saturated soil and poor water diversion
Much of the damage could have been prevented with proper drainage maintenance and storm preparedness.
Essential Pre-Storm Plumbing Checks for Victoria & Sooke Homeowners
1. Inspect Your Perimeter Drain System
Homes in older areas like Oak Bay, Fairfield, and parts of Sooke often have aging perimeter drainage. If your home’s system hasn’t been inspected in several years, consider a camera inspection to identify cracks, root intrusions, or blockages before the rain hits.
2. Test and Maintain Your Sump Pump
If your home has a basement or crawl space, your sump pump is critical. Test it regularly by:
- Pouring water into the sump pit
- Ensuring the float activates the pump
- Confirming the discharge pipe directs water away from your foundation
- Checking for a working battery backup
3. Check Your Backwater Valve
Backwater valves help prevent raw sewage from flowing back into your home during heavy rain. These valves are a must-have in flood-prone neighbourhoods and may even be required by local building codes in some new builds. Learn more from the Government of Canada flood preparedness guide.
If your home doesn’t have one (or you’re unsure if it’s working) we can install or inspect your system.
4. Clean Gutters and Downspouts
While not strictly a plumbing issue, blocked gutters cause rainwater to pool around your foundation, which can lead to leaks and overloaded drains. Clear out leaves, debris, and moss, especially during the fall when Victoria’s trees shed heavily.
5. Watch for Warning Signs
Pay attention to:
- Pools of water around your foundation
- Damp or musty smells in the basement
- Slow-draining sinks and tubs
- Unusual gurgling during rainstorms
These issues may signal trouble in your perimeter drains or sump system.
