Cold showers, rusty water, or a leaking tank? Here's how to tell if it's time to replace your hot water system.
A hot water system rarely fails without warning. Most units give off subtle signs for weeks or months before they finally give up — usually at the worst possible time.
Rusty or Discoloured Water
If your hot water runs brown or rusty, the tank is corroding from the inside. This is common in older steel tanks and usually means replacement is imminent, not repair.
Inconsistent Temperature
Water that starts hot and turns lukewarm quickly often points to a failing heating element or a sediment build-up at the bottom of the tank.
Strange Noises
Popping, rumbling, or banging sounds are caused by sediment hardening on the tank floor. This reduces efficiency and can shorten the unit's lifespan.
Age of the Unit
Most storage tank hot water systems last 8–12 years. If yours is approaching or past this age, it's worth having it assessed before it fails and causes water damage.
