There’s something special about living in an older home — the character, the craftsmanship, the history. But with that charm often comes a hidden challenge: outdated plumbing.
Whether your house was built in the 1940s or just before the building code overhaul in the ‘90s, older homes have plumbing systems that can cause real headaches if they are not inspected and maintained properly.
If you’re starting to notice signs of trouble — slow drains, weird smells, or a mystery leak — it’s probably time to call in the pros. At Tip Top Plumbing, we specialize in helping homeowners navigate the quirks of older systems with reliable, code-compliant plumbing services in Calgary.
Here’s a breakdown of the most common plumbing issues in older homes, why, and how to fix (or prevent) them before they become bigger, messier problems.
1. Galvanized Steel Pipes (and the Trouble They Bring)
Galvanized steel pipes were widely used in homes built before the 1960s. At the time, they were considered a durable solution. But they’ve become one of the biggest plumbing liabilities over the decades.
Why it’s a problem:
- Galvanized pipes corrode from the inside out, leading to reduced water flow and rusty water
- The corrosion often isn’t visible until a pipe bursts
- They can lead to poor water pressure and uneven water temperature
- Lead solder was sometimes used in pipe connections — a serious health risk today
The fix:
We recommend fully repiping galvanized lines using modern materials like PEX or copper. While it’s an investment, replacing these pipes can improve water quality, pressure, and resale value.
2. Cast Iron Drain Lines
Cast iron drain pipes were commonly used until the late 1970s, especially in mid-century homes. They are often hidden in basement walls or buried under floors.
Why it’s a problem:
- Cast iron rusts and flakes over time, which can cause debris buildup
- Cracks and pinholes are common after decades of use
- The internal diameter of the pipe slowly shrinks, leading to slow drains and blockages
- Tree roots can break into the joints if the line runs outside
The fix:
The first step is a video camera inspection. If the pipe is damaged or corroded beyond repair, we can replace it with PVC or ABS piping that meets today’s code. In some cases, trenchless drain replacement is an option to reduce disruption.
3. Outdated Plumbing Fixtures
That vintage sink or clawfoot tub might be charming, but the fixtures underneath often aren’t performing well.
Common signs include:
- Constant drips or leaks
- Inconsistent water pressure
- Difficulty finding parts for repairs
- Fixtures that are not water-efficient, driving up utility bills
The fix:
We offer fixture upgrades that retain the look of your home while improving function and efficiency. From vintage-look faucets to modern low-flow toilets that still match your aesthetic, we can help you blend old-school style with new-school performance.
4. Hidden Leaks and Water Damage
Many older homes were built before the widespread use of vapour barriers or moisture-resistant materials. Combine that with aging pipes, and you have a recipe for hidden water damage.
Warning signs:
- Musty smells, especially near walls or under sinks
- Peeling paint or bubbling drywall
- Flooring that’s warping or discoloured
- Unexplained increases in your water bill
The fix:
We start by using moisture detection tools and thermal imaging to locate the leak. Once identified, we repair the pipe and recommend any drywall or flooring restoration if needed. Left unchecked, these leaks can lead to mould, rot, or foundation issues, so early detection is key.
5. Low Water Pressure Throughout the Home
Low water pressure isn’t just annoying — it can be a sign that your entire system needs attention.
Possible causes in older homes:
- Mineral buildup in galvanized pipes
- Failing pressure regulators
- Leaks in hidden supply lines
- Corroded shut-off valves that no longer open fully
The fix:
We perform a whole-home pressure test and isolate the cause. Solutions might include pipe replacement, pressure regulator adjustments, or installing booster pumps in multi-storey homes.
6. Sewer Line Problems
Sewer backups are a nightmare, and older homes are especially vulnerable due to their age, materials, and shifting foundations.
Common issues:
- Collapsed clay or cast-iron sewer lines
- Tree root intrusion
- Improper slope or outdated connection points
- Bellied sections where waste collects and stagnates
The fix:
Step one is a video inspection. From there, we can recommend hydro-jetting (for cleaning), spot repairs, or complete sewer line replacement. We also offer backwater valve installation, especially useful in flood-prone Calgary neighbourhoods.
7. Lead or Polybutylene Piping
Some older homes in Alberta may still have lead pipes (rare but dangerous) or polybutylene pipes (used in the ‘80s and 90s), which are prone to failure.
Why they’re risky:
- Lead pipes pose serious health risks due to lead leaching into drinking water
- Polybutylene pipes become brittle and crack under normal water pressure over time
The fix:
We recommend immediate replacement of lead with PEX or copper. For polybutylene, we suggest a full repipe, as patching leads to recurring leaks.
Why You Shouldn’t Ignore Plumbing Issues in Older Homes
It’s easy to delay plumbing upgrades when everything seems to be working. However, in older homes, many issues develop silently, and when they surface, they often come with water damage, costly repairs, or health hazards.
By acting early, you can:
- Avoid water damage and insurance claims
- Improve home value with modern plumbing
- Lower water bills with efficient fixtures
- Create a healthier, safer living environment
