After the last frost risk has passed — typically late April to mid-May depending on your Ontario region. This is when outdoor faucets can be safely reconnected, irrigation systems started, and any freeze damage from winter will be detectable.

Testing your sump pump before spring thaw and rainy season. A sump pump failure during heavy spring rain can cause significant basement flooding. Test by pouring water into the pit until the float triggers, confirm the pump starts and stops correctly, and check the discharge pipe is clear.

Open the interior shut-off slowly, then open the outdoor tap. Check inside the wall near the faucet for water staining or damp drywall after turning on water. A frost-split pipe body may not leak until pressure is applied.

Test activation via bucket; verify float moves freely; check inlet screen; confirm discharge is clear and directed away from foundation; verify check valve is functioning; check battery backup condition if equipped.

Spring is a good time to flush a tank water heater if it hasn't been done in the past 12 months. Sediment accumulation reduces efficiency and can damage the tank lining. A plumber can also inspect the anode rod and test the T&P valve at the same visit.

Reconnect outdoor faucets and check for freeze damage; clear roof drain strainers and area drain grates; check window wells and foundation drainage; inspect sewer cleanout covers; verify downspouts direct water away from the building; test all exterior hose bibs.

Yes — rapid spring snowmelt can overwhelm foundation drainage, overtax sump pumps, and flood buildings with inadequate exterior waterproofing. Clear drains, test sump pumps, and ensure grading directs water away from the foundation to reduce this risk.

Many spring tasks can be done by building operators or homeowners. However, freeze-damaged pipes, leaking water heaters, failed PRVs, or a sump pump that won't start require a licensed plumber. Don't delay repairs — water damage is far more costly than plumbing service.
