Warning Signs

Signs You Need This Service

Don't ignore these warning signs — acting early saves money and prevents further damage.

❄️

No Hot Water

The system has stopped working entirely. Could be a pilot light, element, thermostat or tank failure.

🌡️

Lukewarm Water Only

Not getting the temperature you expect? The element, thermostat or gas valve may be failing.

🟠

Rusty or Discoloured Water

Rust-coloured water from hot taps usually means the tank is corroding inside — replacement likely needed.

💧

Leaking from the Tank

A leaking hot water tank is serious — water damage compounds quickly. Call us immediately.

💨

Unusual Noises

Popping, hissing or rumbling from the tank often indicates sediment build-up or a failing element.

📈

Rising Energy Bills

An inefficient or failing system works harder to heat water, showing up as higher gas or electricity costs.
