Is your Hot Water System Ready For This Winter Season?

(Last Updated On: June 13, 2018)

There is nothing worse than waking up in Brisbane on a cold winter morning to find your hot water system isn’t working!

The following signs indicate that it’s time to replace a part of your hot water system or perhaps replace the whole unit:

  1. Water is luke-warm or hot water runs out quickly. This could be a sign that your thermostat or element may be faulty and will require replacement.
  2. Can you see any water leaks? Check all the valves on the hot water unit for drips. Your TPR valve could be leaking if you’re experiencing problems with your hot water.
  3. Check that your hot water system hasn’t split at the seams or looks like it’s expanding out. This is usually caused by a leak inside tank and the tank will need replacement.
  4. Rust spots, rust around the seams or rusty water lines down the tank. Rust doesn’t always mean a leak, but it’s worth having it checked.
  5. Burn marks. If your tank has burn marks up the side it’s a sign that your unit is overheating.
  6. Brown or yellow coloured water. If your water is coming out an unusual colour this is a sign that there’s rust or sediment in the bottom of the tank.
  7. The power keeps tripping when you use your hot water system. This usually means water is leaking onto your thermostat and trips out the fuse.
  8. The ground subsides around the bottom of your tank and the tank starts to lean. This can be caused by rain or a leak that erodes the ground below the tank. The system needs to be disconnected, drained and installed on top of a cement slab. It can pull the pipes off the wall as it tilts if you don’t!


Not all cases require spending money replacing an entire hot water unit. In some cases, simply a part needs replacing. However, if the problem is due to corrosion or age, the whole unit may need to be replaced.
