1. Water at the base of the tank
A puddle under a storage tank, or rust stains running down the side, usually means the inner tank has corroded. Once the tank itself leaks, it cannot be repaired. Plan a replacement before it fails completely.
2. Rusty or discoloured hot water
Brown or rusty water from hot taps only can mean the tank lining is breaking down or the sacrificial anode has been used up.
3. Lukewarm or inconsistent temperature
If showers run cool, or hot water runs out faster than it used to, the thermostat, element, burner or gas control may be failing, or sediment may have built up. It is often fixable, but on an old unit it can be the start of the end.
4. Noises from the tank
Rumbling, popping or banging from a storage tank usually means sediment has built up on the bottom and is overheating. It makes the unit less efficient and stresses the tank.
5. The relief valve keeps dripping
A small discharge while the tank heats is normal. Constant dripping or running means the valve is worn or the water pressure is too high.
6. Pilot or ignition problems
A gas storage pilot that keeps going out, or a continuous-flow unit that shows error codes and shuts down, needs a gasfitter to check the controls, sensors and gas supply.
7. Age
Most storage tanks last about eight to twelve years. If yours is in that range and showing any of the signs above, it is worth getting a replacement quote so you can choose a system calmly rather than in a cold-shower emergency.

Narre Warren soil and pipes
Most of Narre Warren sits on grey and yellow clay that holds water through winter and cracks open in a dry February. Pipes laid in it move a little every season. On the streets built in the 1970s and 1980s that means earthenware sewer joints that have shifted and let roots in. On the 1990s and 2000s estates south of the Princes Highway it usually means PVC lines that have sagged where the trench was backfilled, leaving a dip that collects grease and wipes. Up in Narre Warren North the blocks are bigger and the runs are longer, often to a septic system or a pump. We bring that local knowledge to every job, and we use a camera to confirm what is happening underground rather than guessing at it.

Questions on this topic
How do I find out how old my hot water unit is?
Check the rating plate on the side of the unit. The manufacture date or serial number usually shows the year.
Should I replace my hot water system before it fails?
If it is old and showing warning signs, planning ahead gives you time to compare options and avoid days without hot water.
