Quick Answer: When Should I Do Spring Plumbing Maintenance?

Complete your spring plumbing check between late March and mid-April in Toronto—after the last frost but before heavy spring rains. Focus on inspecting pipes for winter damage, testing your sump pump, and checking outdoor faucets. A thorough inspection takes 1-2 hours and can prevent thousands in water damage.

Key Takeaways

  • Inspect all visible pipes for frost damage, cracks, or bulges
  • Test sump pump monthly during spring—our busiest flood season
  • Turn on outdoor faucets slowly, one at a time
  • Check water heater for rust and flush sediment annually
  • Clear floor drains and fill P-traps to prevent sewer gas
  • Professional inspection costs $150-$350, preventing $5,000+ repairs

Every spring, Toronto plumbers see the same story play out: a homeowner discovers a pipe that cracked during February's deep freeze—now that temperatures have risen, it's leaking into their basement. The damage? Often $5,000 to $15,000 in repairs that could have been caught with a simple spring inspection.

After 28 years of helping GTA families recover from preventable plumbing disasters, I've developed this 15-point checklist. Spend an hour or two now, and you'll save yourself from becoming one of the 3,400+ emergency calls we receive every April. Need help? Call (647) 554-4356 for a professional spring inspection.

Why Spring Plumbing Checks Matter in Toronto

Toronto's climate creates a perfect storm for plumbing problems. Our winters regularly see temperatures drop below -20°C, causing water in pipes to freeze and expand. When spring arrives, that ice melts—and any cracks or damage become active leaks.

According to the Insurance Bureau of Canada, water damage is now the leading cause of home insurance claims in Ontario—surpassing fire. Most spring water damage is preventable with proper inspection.

Toronto's Unique Plumbing Challenges

Several factors make spring plumbing maintenance especially critical in the GTA:

  • Freeze-Thaw Cycles: Toronto experiences 50+ freeze-thaw cycles per winter, stressing pipes repeatedly
  • Clay Soil: Much of Toronto sits on clay soil that shifts with moisture changes, affecting buried pipes
  • Aging Infrastructure: Many homes in Scarborough, Etobicoke, and North York have 50+ year-old plumbing
  • Spring Thaw + Rain: April brings snowmelt AND spring rains—overwhelming drainage systems

How to Test Your Sump Pump (Critical for Toronto Springs)

Testing your sump pump before spring rains can prevent basement flooding

Your sump pump is your first line of defense against basement flooding. In Toronto, sump pumps work overtime during April and May when snowmelt combines with spring rains. A failed sump pump during a major storm can cause catastrophic damage.

1

Check Power Connection

Ensure your sump pump is plugged into a working GFCI outlet. Test the outlet with another device. If you have a battery backup system, check that the battery is charged.

2

Visual Inspection

Remove the sump pit cover and shine a flashlight inside. Look for debris, gravel, or sediment that could clog the pump. The float switch should move freely without obstruction.

3

Water Test

Slowly pour 5 gallons of water into the pit. The pump should activate automatically when the float rises, discharge the water, and shut off. Time how long this takes—pumping 5 gallons should take 10-15 seconds.

4

Check Discharge Line

Go outside and verify water is exiting the discharge pipe at least 6 feet from your foundation. The pipe should be clear of debris and the end should point away from your home.

⚠️ Sump Pump Red Flags

Replace your sump pump immediately if: it makes grinding noises, runs continuously without shutting off, won't activate when water is added, or is more than 10 years old. In Toronto's high-water-table areas like High Park, The Beaches, and Mimico, consider adding a battery backup. Power outages during storms are common.

Checking Outdoor Faucets for Frost Damage

Outdoor faucets (hose bibs) are extremely vulnerable to freezing. Even if you winterized properly, frost can still damage the valve or pipe behind the wall. Here's how to safely check them:

  1. Locate the indoor shut-off valve for each outdoor faucet (usually in the basement near where the pipe exits)
  2. Close the indoor shut-off valve before opening the outdoor faucet
  3. Open the outdoor faucet fully and let any trapped water drain
  4. Have someone inside watch the area behind the faucet for leaks
  5. Slowly open the indoor valve while someone watches the outdoor faucet
  6. Check for proper flow—weak flow may indicate a partial blockage from ice damage

💡 Pro Tip from Mike

If you notice reduced water pressure or any wetness on the interior wall, stop immediately and close the indoor valve. You likely have a cracked pipe inside the wall. Call (647) 554-4356 before using that faucet—running water through a cracked pipe will cause major wall damage.

Water Heater Spring Maintenance

Your water heater works harder in winter and deserves a spring check-up. Here's what to look for:

Visual Inspection Checklist

  • Check for rust on the tank exterior, especially around fittings and the base
  • Look for water pooling around or under the tank
  • Inspect the pressure relief valve—lift the lever briefly; water should flow then stop
  • Check the anode rod (if accessible)—it should be replaced if heavily corroded
  • Verify the temperature setting—120°F (49°C) is recommended for efficiency and safety

Flush Sediment Annually

Toronto's hard water causes sediment buildup in water heaters. This reduces efficiency and shortens tank life. To flush:

  1. Turn off the power (gas or electric) and cold water supply
  2. Attach a garden hose to the drain valve at the tank bottom
  3. Run the hose to a floor drain or outside
  4. Open the drain valve and let water flow until it runs clear (usually 5-10 gallons)
  5. Close the drain, restore water supply, then restore power

Not comfortable doing this yourself? Professional water heater maintenance costs $100-$150 and extends tank life by 2-3 years. Call (647) 554-4356 to schedule.

Floor Drain Maintenance

Basement floor drains often go neglected—until they're needed during a flood. Spring is the time to ensure they're clear and functional.

Testing Floor Drains

  1. Remove the drain cover and clean out any debris
  2. Pour a gallon of water down the drain—it should flow freely
  3. Add 2-3 cups more water to fill the P-trap (prevents sewer gas)
  4. Check for backups in nearby fixtures when flushing toilets

⚠️ Signs Your Floor Drain Needs Professional Help

Contact a plumber if: water drains very slowly, you smell sewer gas even after filling the trap, water backs up when using other fixtures, or you haven't used the drain in years. Old floor drain traps can crack or the line to the sewer may have root intrusion. A professional drain cleaning costs $99-$199.

Inspecting Visible Pipes for Winter Damage

Walk through your basement, crawl spaces, and utility areas with a flashlight. You're looking for signs that pipes froze and expanded during winter:

What to Look For

  • Bulges or blisters in copper or plastic pipes
  • Hairline cracks that may only leak under pressure
  • White mineral deposits indicating past small leaks
  • Green corrosion on copper pipes (active corrosion)
  • Wet spots on walls, floors, or ceilings near pipes
  • Musty smells that could indicate hidden water damage

High-Risk Areas in Toronto Homes

Pay extra attention to these locations where pipes commonly freeze:

  • Exterior walls (especially in older homes without insulation)
  • Under kitchen sinks on exterior walls
  • Unheated garages with plumbing
  • Crawl spaces and under raised porches
  • Near air vents that blow cold air on pipes

If you find damage, don't panic. Mark the location and call a plumber before using that water line. For emergency pipe repairs, Water Pro offers same-day service: (647) 554-4356.

When to Call a Professional

While many spring plumbing tasks are DIY-friendly, some situations call for professional expertise:

Schedule a Professional Inspection If:

  • Your home is more than 30 years old
  • You've had frozen pipe issues in the past
  • You notice any signs of water damage during your inspection
  • Your water pressure has changed since fall
  • You're selling your home (buyers appreciate inspection reports)
  • You want peace of mind before spring rains

Frequently Asked Questions

When should I do spring plumbing maintenance in Toronto?

In Toronto, perform spring plumbing maintenance between late March and mid-April, after the last frost but before spring rains begin. This timing lets you catch winter damage before it causes flooding during April showers. Check Environment Canada for your area's last frost date.

How much does a professional spring plumbing inspection cost?

What are signs of frozen pipe damage after winter?

Signs of frozen pipe damage include: discolored water when first turning on taps, reduced water pressure, visible bulging or cracks in exposed pipes, water stains on walls or ceilings, and musty smells indicating hidden leaks. Check crawl spaces and exterior walls first—these areas are most vulnerable.

How do I test my sump pump for spring?

Test your sump pump by slowly pouring 5 gallons of water into the pit. The pump should activate automatically, discharge the water, and shut off. Check that the discharge pipe directs water at least 6 feet from your foundation. Test monthly during spring—our busiest flood season in Toronto.

Should I turn on outdoor faucets all at once in spring?

No, turn on outdoor faucets one at a time, slowly. First, close the indoor shut-off valve, then open the outdoor faucet to drain any trapped water. Have someone watch inside for leaks, then slowly open the indoor valve. If water doesn't flow or you see damage, keep the valve closed and call a plumber.

What spring plumbing tasks can I do myself?

DIY-friendly tasks include: visual pipe inspections, testing sump pumps, cleaning gutters, checking outdoor faucets, and clearing floor drains. Hire a professional for: water heater maintenance, backflow preventer testing, sewer line camera inspection, and repairing any damage you find during your inspection.

Spring Into Action

A thorough spring plumbing inspection takes just 1-2 hours but can save you thousands in emergency repairs. Toronto's harsh winters stress every pipe, fitting, and fixture in your home—finding problems now, before April rains arrive, is the difference between a minor fix and major flood damage.

Use the 15-point checklist above to systematically check your home. When in doubt, call a professional. A $150-$350 inspection is cheap insurance compared to the average $8,200 basement flood repair.
