No one wants to deal with cold showers, or having to boil the kettle to wash the dishes, so it’s important to make sure your hot water system is operating properly. We’ve put together a few important tips to help you spot the signs that you water heater system may need a service inspection, repair, or replacement.

Fix the Problem Early

Learning to recognise these simple signs will help you to address the problems sooner rather than later. Not only will this prevent you from being surprised by a sudden failure, it could also be the difference between an inexpensive repair and a costly replacement.

Many homeowners tend to neglect the servicing aspect of hot water systems, with plumbers called in only during an emergency. If the system is inspected on a regular basis its working life can be extended. This also ensures improved efficiency and that any repair work can be carried out in a timely manner.

What to Look Out for

You should, of course, have regular maintenance services with a reputable plumber scheduled in, but keep an eye out for these signs. If you notice any of them, call a plumber right away:

  1. Is the water flowing from the tap rusty or brown in colour?
  2. Is the water muddy or does it have sediment in it?
  3. Is the hot water system making strange sounds such as cracking or popping noises?
  4. Has the pilot light gone out? Does this happen often?
  5. Does the hot water have a strange smell or metallic taste?
  6. Are you getting less hot water?
  7. Is water leaking out of the system?
  8. Do you often experience fluctuations in temperature?
  9. Does the water pressure or flow rate vary?
  10. Are you running out of hot water faster than usual?
