Living in an older home has its undeniable charm. The historic architecture, the mature trees in the yard, and the character of the neighborhood all make older homes incredibly desirable. However, these homes also come with their own set of plumbing challenges that are often hidden from view—until something goes wrong. One of our recent clients, residing in an older home in NW Calgary, experienced firsthand the toll that aging plumbing can take. What started as a few minor issues—slow drains, a small leak here and there—soon turned into a series of major problems that left her facing costly repairs. From a failing water heater to corroded pipes and a full sewage backup, the problems escalated quickly.
If you're living in an older home, you may be facing similar issues without even realizing it. Below are the seven most common plumbing problems in older Calgary homes. Identifying these issues early can save you from expensive repairs and ensure that your plumbing system is functioning properly.
In many older homes, galvanized steel pipes were once the standard material for plumbing. Over time, these pipes corrode and rust from the inside, leading to leaks, low water pressure, and potential water damage. Unfortunately, the signs of corrosion are not always visible, and by the time leaks appear, the damage may already be extensive.
In our recent case, the client’s plumbing was still using these outdated galvanized pipes, which were near the end of their life cycle. Corrosion had weakened several sections of the system, and leaks were gradually becoming more frequent. These leaks caused water damage that could have been avoided with proactive pipe replacement.
If you live in an older home with galvanized pipes, it’s important to have them inspected regularly. Consider upgrading to modern materials like PEX or copper, which are more durable and resistant to corrosion. Addressing this issue early can help prevent major water damage and mold growth in your home.
Low water pressure is often a sign of a larger issue in older homes, especially if the problem persists throughout the house. Over time, mineral deposits from hard water can build up inside the pipes, restricting the flow of water. Additionally, older pipes may suffer from corrosion, causing the internal diameter to shrink, which further limits water flow.
Many homeowners don’t realize that low water pressure can also be a sign of a serious plumbing issue, such as a hidden leak or buildup of debris. If not addressed, these problems can worsen, leading to more expensive repairs down the line.
If you notice that your water pressure is lower than usual or inconsistent across multiple fixtures, it’s a good idea to have a plumber inspect your pipes. In some cases, installing a water softener can help reduce mineral buildup and improve flow, restoring the pressure throughout the house.
Slow drains are one of the most common and easily ignored plumbing issues in older homes. Whether it’s the kitchen sink or the bathroom shower, slow drainage is often a sign of a blockage. Over time, debris, grease, hair, and soap scum build up inside the pipes, leading to clogs that can restrict water flow.
In the worst cases, clogs in older pipes can lead to a sewage backup, where waste starts to back up into the home. Tree roots invading the pipes or cracks in old clay pipes can exacerbate these issues, causing significant damage and creating a health hazard.
Addressing slow drains early with regular drain cleaning can prevent these problems from escalating into major backups. If you’re dealing with multiple slow drains or foul odors, it’s a sign that you need to have your plumbing system inspected. A professional plumber can assess the condition of your pipes and recommend the best course of action to clear out blockages and prevent future issues.
Water heaters are essential in every home, but they don’t last forever. The average lifespan of a traditional tank water heater is around 10-15 years, and older units can become less efficient and more prone to failure as they age. If you notice that your water heater is making strange noises, isn’t heating water efficiently, or has started leaking, it may be time for a replacement.
One of the most common signs that a water heater is on its last legs is inconsistent hot water. In older homes, water heaters often haven’t been updated in decades, leading to higher energy bills and less reliable hot water. Replacing your old water heater with a more efficient model—whether it's a tankless water heater or a newer traditional tank unit—can save you money on energy bills and reduce the risk of a sudden failure.
The sewer line is one of the most crucial parts of your plumbing system, yet it’s also one of the easiest to overlook until something goes wrong. In older homes, the sewer lines may be made of clay or cast iron, which are prone to cracking and breaking down over time. Tree roots can infiltrate these pipes, causing blockages that can lead to major sewage backups.
Sewer line problems can be costly to repair and can also cause significant damage to your property. If your home is experiencing frequent clogs, slow drains, or sewage odors, it’s essential to have the sewer line inspected. Advanced technologies like video pipe inspections and trenchless sewer line replacement allow plumbers to identify and fix these issues with minimal disruption to your home and yard.
Leaky faucets, running toilets, and faulty showerheads are some of the most common plumbing issues in older homes. While they may seem like minor inconveniences, these problems can lead to higher water bills and wasted resources. Even small leaks can waste thousands of gallons of water over time, driving up your utility costs.
Upgrading old fixtures to water-efficient models can save you money in the long run. Replacing leaky faucets, showerheads, and toilets with modern, efficient models can reduce water consumption while also preventing future leaks. Many modern fixtures also have features like automatic shut-offs and easy-to-maintain designs, which further reduce the risk of future plumbing problems.
Owning an older home in Calgary means you're likely to encounter a few plumbing issues over time. These problems can range from minor inconveniences to serious, costly repairs. However, by staying on top of routine inspections and addressing issues early, you can avoid major plumbing disasters.
