Hot water is one of those comforts you don’t think much about—until it’s suddenly gone. At Doug the Plumber, we often get calls from homeowners across the Comox Valley who are dealing with unexpected water heater problems.
In many cases, those issues started with small warning signs that were easy to overlook. Catching these signs early can save you from the stress (and cost) of a cold shower, emergency repairs, or a full water heater replacement. Here’s what to watch for.
1. Inconsistent Water Temperature
Are you noticing that your hot water suddenly turns cold, or fluctuates while you’re in the shower? This is one of the most common signs that your water heater is struggling.
What it means:
This could be due to a failing heating element, sediment buildup in the tank, or a malfunctioning thermostat.
2. Strange Noises Coming From the Tank
Popping, rumbling, or banging noises are not normal. These sounds are often caused by sediment hardening inside the tank.
What it means:
As sediment builds up, it creates air pockets that make noise and reduce heating efficiency. Left unchecked, this can cause your tank to overheat or wear out prematurely.
3. Rusty or Discoloured Water
If you turn on the hot water tap and see rusty, brown, or yellow water, your water heater could be the culprit.
What it means:
Corrosion may be occurring inside the tank, or the anode rod may be depleted. If rust is present, the tank could be weakening—and a leak may not be far off.
4. Low Hot Water Pressure
Is your hot water flow weaker than usual? That can be another red flag.
What it means:
Sediment buildup in the tank or pipes may be restricting water flow. This issue won’t improve on its own and often gets worse over time.
5. Water Leaks Around the Tank
Even a small amount of water pooling at the base of your water heater should never be ignored.
What it means:
Leaks can come from connections, pressure valves, or even cracks in the tank itself. If the tank is compromised, replacement is likely the safest option.
6. Age of Your Water Heater
If your water heater is over 10 years old, even minor symptoms can be a sign it’s nearing the end of its lifespan.
What it means:
Older units are more prone to corrosion, inefficiency, and failure. A professional inspection can help you decide whether repair or replacement makes more sense.
