Expert North York Plumber

Frequently Asked Question

• 1. Why is the water pressure so low in my older North York home?

  In homes built in the 1950s and 60s, low pressure usually comes down to the pipes themselves. Many North York homes still have the original galvanized steel supply lines, and these corrode from the inside over decades, narrowing the opening that water flows through. 

  Some older homes also have undersized half-inch main service lines that simply can’t deliver the volume modern households expect. A water pressure test and a camera inspection will tell us whether the cause is corrosion, an undersized line, or something simpler like a failing pressure regulator or a partially closed valve. From there we can recommend the right fix rather than guessing.

• 2. Could my North York home still have lead water service lines, and how do I find out?

  It’s possible. Lead service lines were common in Toronto homes built before the mid-1950s, and many are still in the ground because they’re buried and easy to overlook. The concern is twofold: lead can leach into your drinking water, which is a health risk for young children and pregnant women, and aging lead or galvanized lines are prone to leaks. 

  We can inspect your service line where it enters the basement and confirm the material. If it’s lead, we can replace it with copper through our lead pipe replacement service. The City of Toronto also offers testing for lead in tap water if you want a reading first.

• 3. Is it worth replacing the original plumbing in an older North York house, or should I repair as issues come up?

  It depends on what you find when you look. If your home still has its original galvanized supply lines or a lead service line, those are at the end of their useful life and a full or partial replacement usually makes more sense than repeated repairs that keep adding up. 

  If the system is copper and sound, repairing as issues arise is reasonable. The smart first step is a camera inspection and pressure test so you know the actual condition before deciding. That way you’re spending on what needs it, not replacing pipes that have years left.

• 4. Does the City of Toronto offer a rebate for installing a backwater valve or sump pump in North York?

  Yes. North York falls under the City of Toronto’s Basement Flooding Protection Subsidy Program. The City offers up to 80 percent of the invoiced cost, to a maximum of $1,250 for a backwater valve and up to $1,750 for a sump pump, including eligible labour, materials and taxes. 

  The City announced an expansion of the program for 2026 that raises the totals and adds new categories, so the current maximums are worth confirming on the City’s site before you commit. We install backwater valves and sump pumps to the City’s requirements, which is what keeps your application eligible.

• 5. Is there a rebate for adding a battery backup to my sump pump in North York?

  The City has added a battery backup component to its 2026 program expansion, on top of the existing sump pump subsidy. A backup is worth considering regardless of the rebate, because sump pumps can lose power during severe storms, and rainstorms and power outages often happen together. 

  That’s exactly when your pump needs to keep running. Because rebate categories and amounts were updated for 2026, we confirm the current terms before the work so you know what you can claim. We can install a backup alongside your existing pump or as part of a new sump pump installation.

• 6. What is a combined sewer, and why does it make older North York neighbourhoods more prone to sewer backups?

  A combined sewer carries both wastewater from your home and stormwater runoff in a single pipe. It’s common in Toronto’s older, denser areas. The problem is capacity: during heavy rain, stormwater overwhelms the pipe, and the overloaded sewer can force water backward into basements through floor drains and fixtures. 

  Newer areas separate storm and sanitary flows, but many established North York streets predate that design. A backwater valve is the main defense because it closes automatically when the sewer surcharges and stops the backflow from reaching your basement.

• 7. Why does my basement stay damp even when there's no visible flooding in my North York home?

  Persistent dampness without obvious flooding usually points to groundwater pressure or a failing drainage system rather than a single leak. Many North York homes have weeping tile systems that are now 50 to 70 years old, well past their lifespan, and these often clog with sediment or roots or collapse entirely, so water that should be drained away instead lingers against the foundation. 

  Foundation cracks and high local groundwater add to it. The fix depends on the cause, so we’d inspect the foundation, check whether your sump and weeping tile are working, and identify where moisture is entering before recommending anything.

• 8. Which pipes in my older North York home are most at risk of freezing in winter?

  The most vulnerable are pipes running through unheated or poorly insulated spaces: exterior walls, unheated basements and crawlspaces, garages, and the hose bib on the outside of the house. 

  Older North York homes are especially exposed because insulation standards were lower when they were built, and a deep cold snap like the one in January 2026 is when burst lines tend to happen. 

  Keeping these areas above freezing, insulating exposed pipe, and disconnecting outdoor hoses before winter all help. If a pipe does freeze, we offer frozen pipe repair and thawing, and it’s worth acting fast before a frozen line bursts.
