Why does my tap water smell like chlorine?
A familiar smell. An important purpose. Understand how your water is treated—and explore options for the taste and odour you prefer.
Three things worth knowing.
It has a purpose.
Melbourne’s water treatment can include chlorine or chloramine to help control disease-causing microorganisms. Treatment varies with the source and supply system.
Smell is not a safety test.
The way water smells cannot confirm whether it is safe. A sudden or unusual change should be raised with your water supplier rather than diagnosed by smell alone.
The disinfectant matters.
Ask whether your supply uses chlorine or chloramine. A filter’s chlorine reduction claim should not be assumed to demonstrate the same performance for chloramine.
Protection along the way.
Melbourne Water treats and disinfects drinking water before it enters the supply network. The treatment used depends on the source and system.
01
Water source
Water enters the supply system from catchments and other sources.
02
Treatment
Chlorine, chloramine or UV can be used to control disease-causing microorganisms.
03
Distribution
A disinfectant residual can help protect water as it travels through the network.
04
Your home
Taste and smell can vary. Your retailer can explain your local supply.
From a drinking tap
to connected showers.
Removing a disinfectant also changes protection within downstream plumbing. Correct installation, hygiene and regular maintenance remain important. Follow any official boil-water or do-not-drink advice even if you have a filter.
If the concern is at the kitchen tap.
Discuss an under-sink option with a documented reduction claim for the taste or odour concern. Compare cartridge capacity and replacement requirements.
If the concern is across the home.
A whole-house system may be considered for connected outlets. Confirm the intended treatment at the expected flow, not just the number of filter stages.
If something changes unexpectedly.
Note whether the issue affects hot water, cold water or several taps. Ask the supplier or a qualified plumber about unusual changes, especially if there is discolouration or a notice affecting your supply.
Different moments.
The same water supply.
Start with where you notice the smell, then match any filtration to that outlet and the treatment your water needs.
At your drinking tap
If chlorine taste or odour is your concern, a suitable carbon filter may help. Confirm the cartridge’s specific reduction claims.
In your shower
Whole-house filtration serves connected showers as well as taps. Check performance at your household’s required flow rate.
When preparing food
A dedicated under-sink outlet can supply water for drinking and food preparation without treating every tap in your home.
Chlorine and chloramine.
Not the same filter question.
Chlorine
A commonly used disinfectant. Activated carbon can reduce chlorine taste and odour when the cartridge is suitable and maintained.
Chloramine
A disinfectant formed from chlorine and ammonia. Confirm a specific chloramine reduction claim; a chlorine claim alone is not enough.
Your questions,
answered clearly.
Why do I notice it more in the bathroom?
Showering creates a different experience from filling a glass: warm water, spray, ventilation and time spent in the room can affect what you notice. A smell alone does not establish its cause or concentration.
Does it vary between homes?
Water source, treatment and conditions within a property can differ. Ask your water retailer for information specific to your supply zone.
Will a shower filter solve it?
Only if the particular filter is suitable for the concern and its operating conditions. Check evidence at shower flow rates and temperatures; it will not treat other outlets.
