How to Prepare Your Drains for Rainy Season in Greater Vancouver
Greater Vancouver’s rainy season can be brutal on drainage systems. What starts as a minor slowdown can quickly turn into major backups, flooded basements, or soggy yards when the heavy rains arrive.
Preparing your drains before the wet months is one of the smartest things you can do as a homeowner.
Why Rainy Season Is Hard on Drains
During our long wet season, drainage systems face extra stress:
- Increased water volume from rain and roof runoff
- Tree roots become more active as they seek water
- Silt and debris get pushed deeper into pipes
- Older or partially clogged systems can fail suddenly
Taking action before the rain starts can prevent most emergencies.
Essential Steps to Prepare Your Drains
- Schedule Professional Hydro Jetting
This is the single most effective preparation step. Hydro jetting removes built-up grease, sludge, and early root growth, giving your pipes maximum capacity before the heavy rains hit. Best timing: Late summer or early fall.
- Get a Drain Camera Inspection
A camera inspection shows the true condition of your pipes, French drains, and main line. It can reveal hidden problems (like root intrusion or pipe damage) that aren’t visible yet.
- Clean Gutters and Downspouts
Clogged gutters send massive amounts of water directly next to your foundation and into your yard drains. Clean them thoroughly and extend downspouts away from the house.
- Check and Clean Catch Basins
Remove leaves, dirt, and debris from any outdoor catch basins or area drains. This prevents them from overflowing during heavy storms.
- Inspect Grading Around Your Home
Ensure the ground slopes away from your foundation. Small low spots can turn into big problems when the rain comes.
Additional Rainy Season Protection Tips
- Trim back tree branches near drain lines
- Avoid putting food waste or grease down the kitchen sink
- Test your sump pump (if you have one) to make sure it’s working
- Consider installing a backwater valve if you don’t have one
