Basement Flood Prevention Checklist

Why this matters in Brampton

Much of Brampton was built on clay soil that drains slowly, and newer subdivisions have the foundation weeping tile pumped to a sump rather than draining by gravity. When a summer thunderstorm dumps a month of rain in an afternoon, the sanitary and storm systems in older parts of the city can surcharge, and sewage can push back up a basement floor drain. The City of Brampton and the Region of Peel have run programs encouraging backwater valves and downspout disconnection; check their current pages for what is offered this year.

Step by step

Spring

1. Pour a pail of water into the sump pit and see the float rise and the pump clear it. Listen for grinding or a motor that hums without moving water.
2. Outside, confirm the discharge pipe is clear and ends a couple of metres or more from the foundation, not against a neighbour's lot line.
3. Open the access lid on your backwater valve and look for debris on the flap. Make sure the flap swings freely.

Summer

1. Clean leaves and seed pods out of the eavestroughs, especially under the maples common on older Bramalea streets.
2. Check that downspout extensions are attached and point away from the house.
3. Look at the soil along the foundation. It should slope away; settled flower beds often slope back toward the wall.

Fall

1. Test the sump again before the November rains, and if your pump has a battery backup, test that unit by unplugging the main pump.
2. Disconnect hoses and shut the inside valves for outdoor taps.
3. Make sure nothing in storage sits directly down on the slab beside the floor drain.

Mistakes to avoid

• Plugging a sump pump into an extension cord laid across a wet floor.
• Pouring cooking fat down the kitchen sink. Solid grease narrows the line, and a narrowed lateral backs up sooner during a storm.
• Paving over the backwater valve access or building a closet wall in front of it.
• Assuming a pump that is ten years old will start the one time it really matters.

when to phone a plumber

Phone us if the pump cycles every minute in dry weather, if water seeps up around the floor drain, or if you smell sewer gas in the basement. We can replace a tired pump (see sump pump installation), fit a full-port mainline backwater valve under a permit, or run a camera through the lateral to see if roots or a sag are slowing it down.

Ready when you are. One call, a real plumber, an arrival window.
