If you own an older home in London Ontario, heritage plumbing tells a complicated story. You can read part of that story just by looking at your bathrooms. One renovated in the 70s. Another in the 90s. A kitchen updated in the 2010s. However what’s behind the walls tells a different story entirely.
I’m Aron Oretan — a Licensed Red Seal Plumber and Steamfitter with 26 years in the trade. I live in Old South. I’ve worked in these homes my entire career. Here’s what heritage plumbing in London Ontario actually looks like — and what it means for you as a homeowner.
Why Heritage Plumbing in London Ontario Is Different
Century homes in London Ontario get renovated over and over again. Each renovation involves different owners, different budgets, and different standards. As a result, layers of plumbing from different eras end up stacked on top of each other behind your walls.
The most common problem I find is old pipe that should have been replaced — but wasn’t. Instead someone connected new pipe to old with a coupling. They did half the job and walked away. The new work looks fine. However the old pipe behind it is still there. Still failing. Still causing problems. You just can’t see it until something goes wrong.
The Five Pipe Types I Find in Older London Homes
Most homeowners can’t tell different pipe types apart. That’s fine — identifying them is my job. So when I walk into a heritage home in Old South or Wortley Village, I assess every pipe I find and explain exactly what each one means for the homeowner.
Lead service lines. Lead water mains still run into homes all over London’s older neighbourhoods. This is a health issue. Lead leaches into drinking water — especially when water sits in the line overnight. Furthermore if your home was built before the 1950s and you’ve never replaced your water main, there’s a good chance you still have a lead line. The City of London offers a free lead testing program. Start there.
Galvanized water pipe. Galvanized steel water lines rust from the inside out. Over decades that rust narrows the inside of the pipe. As a result water pressure drops. Eventually the pipe fails completely. You can’t see it happening — you just notice the pressure getting worse year by year.
Galvanized drain pipe. Same material, same rust problem. However galvanized drains carry an additional risk. When they clog, they are extremely difficult — sometimes impossible — to snake out. The rust grabs onto the snake. In fact the pipe itself can crack under pressure. What looks like a simple drain cleaning job can turn into a full pipe replacement.
Old cast iron pipe. Cast iron still gets used in modern commercial buildings. However old cast iron in a century home behaves very differently. It becomes brittle over time. It can crack on its own — without any external force. When it goes, it goes without warning.
Clay and asbestos pipe underground. Below the foundation you can still find clay and asbestos drain lines in older London homes. Clay is porous — tree roots sense the moisture inside and grow straight through the pipe walls. Asbestos pipe fails at the gasket joints between sections. Both require camera inspection before any work begins.
What Happens When Old Heritage Plumbing Finally Fails
Old pipe doesn’t always fail dramatically. Sometimes it’s slow. A drain that takes a little longer to clear. Water pressure that’s never quite right. A smell that comes and goes.
Other times it’s sudden. A galvanized drain that can’t be snaked. A cast iron section that cracks during a routine job. A lead line that shows up on a water test.
In either case the process is the same. First I identify the pipe type causing the problem. Then I explain what’s happening and why. After that I lay out the options based on how much pipe is affected and what budget makes sense for the situation.
Your Options When Old Pipe Needs Attention
Sometimes full replacement is the right answer. Other times we replace only the problem section and leave the rest in service. And sometimes — when the pipe is stable and the budget doesn’t allow for more — we monitor it and plan for future work.
There’s no one-size-fits-all answer in a century home. Every house is different. My job is to give you an honest picture so you can make an informed decision based on real information — not guesswork.

Why Heritage Plumbing Needs a Plumber Who Knows It
Not every plumber is comfortable in a century home. The rough-ins don’t follow modern standards. The pipe materials require different tools and different techniques. Furthermore what you find behind the wall is rarely what you expected going in.
I live in Old South. I’ve been working in these homes since I started in the trade. I know what galvanized drain pipe feels like when you’re snaking it. Old cast iron tells its own story — you can hear it getting brittle before it breaks. And experience teaches you when to push forward and when to stop before something worse happens.
That experience matters in a heritage home. More than anywhere else.
What to Do if You Own an Older Home in London Ontario
You don’t need to replace everything at once. However you do need to know what you have. A proper plumbing assessment gives you that picture.
Start with a water test if your home predates the 1950s. Find out whether you have a lead service line. Then ask about the condition of your water and drain lines. A good plumber walks you through what’s there, what’s at risk, and what can wait.

Frequently Asked Questions About Heritage Plumbing in London Ontario
How do I know what pipes are in my older London Ontario home? Most homeowners can’t identify pipe types by sight. However a licensed plumber can. If your home was built before the 1970s it likely has a mix of pipe materials from different eras. A plumbing assessment gives you a clear picture of what you have and what condition it’s in.
Is galvanized pipe dangerous in an older London home? Galvanized pipe isn’t dangerous the way lead is. However it rusts from the inside out over time. That rust reduces water pressure and eventually causes failure. Furthermore galvanized drains become nearly impossible to snake out when they clog — which makes them a bigger problem than most homeowners realize.
Should I replace all the old pipe in my heritage home at once? Not necessarily. The right approach depends on the condition of the pipe, how much needs attention, and your budget. Sometimes full replacement makes sense. Other times replacing the problem sections is the practical choice. A licensed plumber helps you prioritize.
What is a lead service line and does my Old South home have one? A lead service line is the underground pipe running from the city water main into your home. Homes built before the 1950s commonly have them. The City of London offers a free lead testing program. If results show elevated lead, water main replacement is the right conversation to have.
Can clay or asbestos drain pipes be repaired without digging? Sometimes. Depending on the extent of the damage, drain patching or relining can address specific problem sections without full excavation. However a camera inspection tells us exactly what we’re dealing with before any decisions are made.
How much does it cost to repipe a heritage home in London Ontario? Every home is different. Cost depends on the pipe type, how much needs replacing, and how accessible the pipes are. Some projects are straightforward. Others involve opening walls and floors. Contact Triton for an honest assessment and quote based on your specific home.
