Hot water tanks are one of the most relied-upon systems in Calgary homes. From morning showers to laundry and dishwashing, your tank works hard every day, especially during long, cold winters. Yet many homeowners only think about their hot water tank when something goes wrong. 
Regular maintenance is the key to avoiding unexpected failures, saving money, and ensuring your family always has reliable hot water. This guide explains how to maintain your hot water tank, common issues Calgary residents face, and why Aquality Plumbing & Heating is the trusted choice for repairs, replacements, and ongoing service.
Why Hot Water Tank Maintenance Matters
A well-maintained hot water tank can last 8–12 years, sometimes longer. Without maintenance, sediment buildup, corrosion, and worn components can dramatically shorten its lifespan. In Calgary, where hard water and heavy winter usage put extra stress on tanks, maintenance is not optional; it’s essential.
Benefits of regular maintenance include:
- Longer lifespan for your tank.
- Improved energy efficiency and lower utility bills.
- Reduced risk of leaks and costly water damage.
- Consistent hot water supply for your household.
Common Hot Water Tank Issues in Calgary
- Sediment buildup – Calgary’s hard water leaves mineral deposits that settle at the bottom of the tank, reducing efficiency and causing overheating.
- Corrosion – Without regular inspection of the anode rod, tanks can rust and leak.
- Pressure problems – High water pressure accelerates wear and tear.
- Temperature fluctuations – Faulty thermostats or heating elements can cause inconsistent water heating.
- Leaks – Small leaks often signal bigger problems ahead.
Step-by-Step Maintenance Tips
Flush the Tank Annually
Sediment buildup is the most common issue. Flushing the tank once a year helps remove deposits and keeps the system running efficiently.
How-to:
- Turn off the power or gas supply.
- Connect a hose to the drain valve.
- Drain several litres until the water runs clear.
- Refill and restart the tank.
Inspect the Anode Rod
The anode rod prevents corrosion by attracting minerals that would otherwise cause it. Check it every 2–3 years. If it’s worn down to less than 1.5 cm, replace it.
Test the Pressure Relief Valve
Lift the valve’s lever to ensure water flows out; if it doesn’t, replace the valve immediately.
Check the Thermostat Settings
Set the temperature to 49°C (120°F). This prevents scalding, saves energy, and reduces stress on the tank.
Check for Heat Loss
Lack of Insulation increases heat loss and may cause freezing in Calgary’s cold winters.
FAQs About Hot Water Tank Maintenance For Calgary
Q: How often should I flush my hot water tank?
At least once a year. In areas with hard water, it is recommended to do this twice a year.
Q: Can I do maintenance myself?
Basic tasks, such as flushing, are manageable, but inspections and repairs should be left to licensed technicians.
Q: How do I know if my tank needs replacement?
If your tank is over 10 years old, leaking, or struggling to provide hot water, replacement may be more cost-effective than repair.
