Common Water Heater Problems in Mississauga (and How Local Experts Fix Them)

Few things are more frustrating than stepping into a cold shower on a winter morning in Mississauga. Your water heater plays a crucial role in daily comfort,  from warm showers and dishwashing to laundry and cleaning. But like any mechanical system, it can run into problems over time.

Whether your unit isn’t heating properly, leaks are forming around the base, or the pilot light keeps going out, these are all signs your system needs attention. Understanding the most common water heater problems in Mississauga, and how local experts fix them , can help you know when to call for help before a small issue turns into a costly repair.

1. No Hot Water or Inconsistent Heating

If your water heater suddenly stops producing hot water, or the temperature fluctuates, several culprits could be to blame. For gas water heaters, the issue might be a faulty thermocouple or pilot light, while electric models often suffer from burned-out heating elements or thermostat malfunctions.

Sometimes, sediment buildup in the tank can also prevent the heater from reaching the correct temperature. A qualified technician will test your system’s electrical components, flush the tank if needed, and make sure all connections are secure.

2. Water Leaking from the Tank or Fittings

A small leak might not seem urgent, but it can quickly turn into a major problem if ignored. Leaks can stem from loose fittings, rusted pipes, or corrosion inside the tank itself. Over time, these issues weaken the system’s structure and reduce efficiency.

Local Mississauga repair experts typically start by inspecting the pressure relief valve and drain connections to pinpoint the source of the leak. If the tank itself is damaged, replacement is often the only safe option.

Ignoring leaks can lead to mold growth, water damage, and increased energy costs , so early detection is key to avoiding expensive repairs.

3. Pilot Light Won’t Stay Lit

If you have a gas water heater, the pilot light is what keeps your system running. When it refuses to stay lit, you’re left without hot water. Common causes include a dirty thermocouple, a blocked gas line, or drafts that extinguish the flame.

A licensed technician will safely clean or replace the thermocouple, check gas pressure, and ensure the flame burns correctly. It’s never a good idea to attempt DIY gas repairs , working with a trained professional ensures safety and long-term performance.

4. Strange Noises from the Water Heater

Popping, rumbling, or banging sounds coming from your water heater usually indicate sediment buildup at the bottom of the tank. As the burner heats the trapped water under the sediment, it creates those loud noises.

Sediment reduces efficiency and can eventually cause cracks or leaks in the tank. The solution is usually a professional flush and cleaning, which removes debris and restores normal operation. In hard water areas like Mississauga, scheduling an annual maintenance visit helps prevent sediment from accumulating again.

5. Low Hot Water Pressure

Weak or fluctuating water pressure from your hot taps may not always be caused by the heater itself, it can also stem from mineral deposits in pipes or blockages in the unit’s inlet valve.

If your home’s plumbing is older, sediment can build up over years of use. A technician will check for clogs, clean filters, and ensure proper water flow through the system. Consistent water pressure not only improves comfort but also helps the water heater run more efficiently.

6. Rusty or Cloudy Hot Water

Discoloured or cloudy hot water often points to corrosion inside the tank or a deteriorating anode rod. In electric models, mineral deposits can also affect clarity and taste.

If you notice rusty water coming only from the hot tap, the tank is likely the issue, not your plumbing. Replacement of the anode rod may help if caught early, but once corrosion spreads, it’s usually time for a new unit.

For some homeowners, this becomes an opportunity to consider upgrading to a tankless water heater, which eliminates stored water and the risk of rust altogether. Local technicians can help you decide if that’s the right solution for your home.
