April in the GTA means one thing for your basement: water. Snowmelt, spring rains, and rising water tables put thousands of GTA basements at risk every year. Your sump pump is the last line of defense — but only if it's working.

The 10-Minute Check

Step 1: Locate your sump pit and remove the cover. Look for debris — sediment, gravel, and small objects can clog the intake.

Step 2: Pour a bucket of water into the pit. The pump should activate automatically when the water reaches the float switch. If it doesn't, check the power connection first.

Step 3: Listen for unusual sounds — grinding, rattling, or continuous running are warning signs.

Step 4: Follow the discharge pipe outside. Make sure it's clear of ice, debris, and isn't frozen. The discharge should empty at least 6 feet from your foundation.

Step 5: Check the check valve. Water should only flow one direction — out. A failed check valve lets water drain back into the pit, causing the pump to cycle endlessly.

When to Call a Pro

If your pump is over 7 years old, makes unusual noises, or cycles more than 4 times per hour during moderate rain, it's time for a replacement. Average cost in the GTA: $800–$1,800 installed.
