Recognizing the Signs: When to Call for Water Heater Service

A proactive approach to water heater care can prevent costly emergencies. Be vigilant for these common warning signs that indicate your system needs professional attention:

  • Inconsistent or No Hot Water: The most obvious sign. If your showers are suddenly cold or your dishwasher isn’t cleaning properly, it could point to a failing heating element, a compromised tank, or sediment buildup.

  • Discolored or Rusty Water: Brownish or rusty water from your hot water taps often signals corrosion inside the tank. This is a serious concern that can lead to leaks and indicates the unit may be nearing the end of its service life.

  • Unusual Noises: Rumbling, popping, or banging sounds are typically caused by sediment (mineral deposits from hard water) hardening at the bottom of the tank. This sediment layer forces the heater to work harder, reducing efficiency and accelerating wear.

  • Leaks or Moisture Around the Unit: Any pooling water or consistent moisture around the base of the heater is a critical red flag. It often means the tank itself has corroded and may be on the verge of a major failure.

  • Advanced Age: The average lifespan of a traditional tank water heater is 8-12 years. If your unit is within or beyond this range and showing any of the above symptoms, replacement is likely more cost-effective than repeated repairs.

If you notice any of these issues, don’t wait for a complete breakdown. Contacting Option One Plumbing promptly can often save you money and prevent water damage to your property.

The Critical Role of Annual Maintenance

Many homeowners overlook maintenance until a problem arises. However, regular maintenance is not just recommended; it is a requirement to keep most manufacturers’ warranties valid. At Option One Plumbing, we emphasize that a simple yearly service can dramatically extend the life of your investment and ensure it runs safely and efficiently.

Our core maintenance service involves flushing the tank to remove accumulated sediment. This sediment acts as an insulator, forcing the heater to use more energy (gas or electricity) to heat your water, which increases your utility bills. Removing it restores efficiency and protects the tank from corrosive damage.

Furthermore, our certified technicians will assess your system for important safety and efficiency upgrades, such as installing a thermal expansion tank. This device counters the pressure caused by water expanding when heated, reducing stress on your water heater, pipes, and fittings. In many areas, including parts of Ontario, installing a thermal expansion tank is mandated by local plumbing codes to ensure system safety.

Making the Choice: Traditional Tank vs. Tankless Water Heaters

When it’s time for a new installation, Ontario homeowners have a fundamental choice to make. Option One Plumbing’s experts will guide you through the pros and cons of each system to find the perfect fit for your household’s needs and budget.

Traditional Storage Tank Water Heaters are the familiar model found in most homes. They continuously heat and store a large reservoir of water (typically 40-80 gallons), making hot water instantly available. The primary considerations are their larger physical footprint and the “standby” energy loss from constantly reheating the stored water.

Tankless (On-Demand) Water Heaters represent the modern, high-efficiency alternative. They heat water directly as it flows through the unit, eliminating standby energy loss. The benefits are significant:

  • Energy Savings: By only heating water when you need it, tankless models can be up to 34% more energy-efficient for homes that use 41 gallons or less of hot water daily.

  • Endless Hot Water: Since water is heated on demand, you’ll never “run out” during a long shower or while running multiple appliances.

  • Space Savings: Their compact, wall-mounted design frees up valuable floor space in your garage or utility room.

  • Longer Lifespan: A well-maintained tankless system can last more than 20 years, nearly double that of a traditional tank.

Our team will discuss your household’s hot water usage, upfront budget, and long-term savings goals to help you determine which system offers the best value and comfort for your home.
