- Check the age of your hot water tank. Look for a large white and black sticker for this information, this sticker also called the rating plate, has important information related to your tank, such as model, serial number, age and size. In many Canadian cities as a result of our hard water your tank should typically last 8 – 12 years. If your tank is nearing the end of this range then it might be time to think about replacing or installing a water detection device to alert you in case a water leak occurs such as single-use water alarms in the area, or a Flo by Moen system on your main water valve. While a Flo by Moen system is a large investment in your home, it will not only detect leaks stemming from your hot water tank but also other household fixtures and pipes and automatically shut off the water main when triggered.
- Have a listen to your tank. Do you hear any strange sounds such as popping, knocking, or rumbling? This could be a sign of sediment buildup and could lead to reduced efficiency and even damage to your tank.
- Have you noticed inconsistent hot water supply or fluctuating temperatures? Is the hot water taking longer to reach the tap than it used to? If so your tank may be losing efficiency and nearing the end of life.
- Check for corrosion on the outside of your tank. Look at the valves and hoses running into your tank, do you notice any white crusty buildup on them? This corrosion could be a sign of a small leak.
- Does your water appear discoloured or rusty at times? You may also notice a change in your water’s taste. The change in appearance or taste is also another indication that your tank is nearing the end of life and will need to be replaced.
How to Replace Hot Water Tank?
Replacing a hot water tank involves several steps to ensure safety and compliance with local regulations. Here’s a step-by-step guide: 1. Check Local Regulations and Permits- In many cities in Canada, you may need a plumbing permit for hot water tank replacement.
- Check with your City or consult a licensed plumber to ensure compliance.
- Gas Tank: Turn off the gas supply and the pilot light.
- Electric Tank: Switch off the breaker at the electrical panel.
- Water Supply: Shut off the cold water supply valve.
- Attach a hose to the drain valve at the bottom of the tank and lead it to a floor drain.
- Open the drain valve and a hot water tap to let air in, speeding up the drainage process.
- Gas Tanks: Disconnect the gas line carefully.
- Electric Tanks: Disconnect the wiring (make sure to label connections).
- Detach the water inlet and outlet pipes.
- Once drained and disconnected, carefully remove the old tank.
- Be cautious, as tanks can be heavy and may still contain some water.
- Clean the area and ensure proper ventilation for gas models.
- Check that the new tank matches the size and capacity of the previous one.
- Position the new tank.
- Reconnect the water supply, ensuring tight connections to avoid leaks.
- Connect the gas line or electrical wiring.
- Fill the tank with water by opening the cold water supply and letting air escape through a hot water tap.
- Gas Tank: Light the pilot and check for gas leaks using a leak detection solution.
- Electric Tank: Restore power and check for proper heating.
- Monitor for leaks around the tank and connections.
- If you’re not confident in DIY installation, consider hiring a licensed plumber.
Pro Tips:
- Hire a Pro: Ordering professional plumbing services Calgary ensures the job meets safety codes.
- Energy Efficiency: Consider upgrading to a high-efficiency or tankless water heater.
In many Canadian cities, due to hard water conditions, hot water tanks typically last between 8 to 12 years. It’s advisable to check the manufacturer’s sticker on your tank for specific details.
Key indicators include:
Age: If your tank is nearing or has surpassed the 8-12 year range.
Strange Noises: Sounds like popping, knocking, or rumbling may indicate sediment buildup.
Inconsistent Hot Water: Fluctuating temperatures or delayed hot water delivery.
Corrosion: Visible rust or white crusty buildup on valves and hoses.
Discolored or Rusty Water: Changes in water appearance or taste.
Locate the rating plate on your tank, which displays essential information such as the model, serial number, age, and size.
Corrosion or leaks, especially around valves and hoses, are signs that your tank may be failing. It’s recommended to consult a professional plumber to assess the situation and discuss potential replacement options.
Regular maintenance, such as flushing the tank to remove sediment and inspecting for signs of wear, can help prolong its lifespan. Additionally, installing water detection devices can alert you to leaks early, minimizing potential damage.
If you delay replacing an aging hot water tank, you risk leaks, inefficient heating, increased energy costs, and potential water damage from a tank failure. Over time, sediment buildup can reduce efficiency and damage the unit.
It is recommended to flush your hot water tank at least once a year to remove sediment buildup. This helps maintain efficiency and prolongs the lifespan of your tank.
A traditional hot water tank stores and heats a set amount of water, while a tankless water heater heats water on demand. Tankless systems are often more energy-efficient and have a longer lifespan.
Some issues, such as a faulty thermostat or heating element, can be repaired. However, if the tank itself is corroded or leaking, replacement is usually the best option.
The right size depends on the number of people in your household and your water usage. A family of 1-2 people may need a 30-40 gallon tank, while a larger household of 4+ may require a 50-80 gallon tank.
