Common Water Heater Problems We Fix in London Ontario
London Ontario’s hard water — with moderate to high mineral content — accelerates sediment buildup inside water heater tanks, reducing efficiency and shortening unit lifespan.
Here are the most common water heater issues our team resolves:
No Hot Water A complete loss of hot water is the most urgent water heater situation. On electric units, the most common cause is a failed heating element or a tripped breaker. On gas units, a faulty thermocouple, a failed pilot light, or a gas supply issue are the typical culprits. We diagnose and repair on the first visit.
Insufficient or Inconsistent Hot Water If your water heater runs out of hot water faster than it used to, or the temperature fluctuates during use, the tank may be undersized for your current household demand, the thermostat may have drifted, or sediment buildup may be reducing the effective tank capacity. We assess all three causes before recommending a solution.
Water Heater Leaking A leaking water heater requires same-day attention. Leaks from the pressure relief valve are often a sign of excessive tank pressure — a safety issue. Leaks from the tank body itself usually indicate internal corrosion and mean the unit needs replacement. Leaks from supply line connections are generally repairable without replacing the unit.
Discoloured or Foul-Smelling Hot Water Rusty or brown hot water typically indicates internal tank corrosion or a failing anode rod. A sulphur or rotten egg smell in hot water is almost always caused by a reaction between the anode rod and bacteria in the water supply. Both issues are diagnosable and often treatable without replacing the full unit.
Unusual Sounds from the Tank Rumbling, popping, or banging sounds from a water heater tank are almost always caused by sediment buildup on the tank floor. As the heating element heats water trapped beneath the sediment, it creates the sounds. A tank flush resolves the issue if caught early — left too long, the sediment causes permanent damage.
Signs Your Water Heater Needs Repair or Replacement in London Ontario
Your unit is over 10 years old The average tank water heater in London Ontario lasts 10 to 12 years. If yours is approaching or past that mark and showing any symptoms, repair costs will likely keep climbing — making replacement the more practical investment.
Hot water runs out faster than it used to Reduced hot water capacity is a reliable sign of significant sediment accumulation or a failing heating element. Both are diagnosable on the first visit.
You’re paying more to heat water without using more A steady increase in your energy bill without a change in usage is a sign your water heater is working harder than it should — often due to sediment insulating the heating element from the water.
Rust-coloured water only from the hot tap If cold water is clear but hot water is discoloured, the problem is inside the water heater, not the supply line — likely internal corrosion or a failed anode rod.

Frequently Asked Questions About Water Heater Repair & Installation in London Ontario
How long does water heater installation take in London Ontario?
Most standard tank water heater installations in London Ontario take between two and three hours, including removal of the old unit and final testing. Tankless water heater installations may take longer depending on venting requirements and electrical or gas line modifications.
What is the difference between a tank and tankless water heater?
A tank water heater stores and continuously heats a fixed volume of water — typically 40 to 60 gallons — ready for use. A tankless unit heats water on demand as it flows through the unit, using energy only when hot water is actually needed. Tankless units cost more upfront but use significantly less energy and never run out of hot water. We can help you assess which is right for your household’s usage pattern and budget.
How long does a water heater last?
Tank water heaters typically last 10 to 12 years in London Ontario. Hard water accelerates sediment buildup and anode rod depletion, which can shorten lifespan — making annual maintenance worthwhile. Tankless units generally last 15 to 20 years with regular descaling service.
Do you service all water heater brands in London Ontario?
Yes. Our team services and installs all major tank and tankless water heater brands available in London Ontario, including Rheem, Bradford White, A.O. Smith, Navien, Rinnai, Noritz, and others. If you have a less common brand, call us and we’ll confirm parts availability before scheduling.
How much does water heater repair cost in London Ontario?
The cost depends on the nature of the problem. Replacing a heating element or thermostat is one of the more affordable water heater repairs in London Ontario. A pressure relief valve replacement or anode rod service costs more depending on access and parts. We provide a fixed written quote before starting any work — no surprises on the final bill.
