Signs Your Hot Water System Might Need Repairs

Your hot water system plays a crucial role in your daily routine, so it’s important to catch potential issues early. Here are some common warning signs:

Inconsistent Water Temperature

Sudden hot-and-cold fluctuations or lukewarm water often point to a faulty thermostat or heating element.

Unusual Noises

Popping, rumbling, or hissing sounds? This could mean sediment buildup inside the tank, affecting efficiency.

Leaks or Water Pooling

A leaking unit may indicate a failing pressure valve, excess water pressure, or cracks in the tank.

Rusty or Discoloured Water

Brown or rusty water suggests corrosion inside the tank or pipes, requiring urgent attention.

Old System (8-12 Years)

Frequent breakdowns in older systems can mean it’s time for repairs or a full replacement.

Helpful Tip

If your hot water stops working, check your power supply or gas connection first—sometimes, a simple reset can solve the problem.

Hot Water Repair vs. Replacement – What’s Best?

Our licensed plumbers will assess your system in our call-out inspections and recommend the most cost-effective solution.

Not sure if you should repair or replace your hot water system? Here’s what to consider:

System Age

If your unit is over 10 years old and constantly failing, replacement may be the better option.

Issue Severity

Minor thermostat or heating element issues can often be fixed, while major leaks or corrosion might require a full upgrade.

Cost Comparison

If repairs exceed 50% of a new system’s cost, upgrading to a more energy-efficient model may save you money in the long run.

Helpful Tip

To extend the life of your system, flush the tank annually to remove sediment buildup and improve efficiency.
