Why does my tap water smell of chlorine?
Chlorine has a role in disinfection. Here is how to separate a taste preference from a water quality concern when choosing treatment in Armenia.
Chlorine has a purpose
Chlorine is used to disinfect drinking water. Veolia Djur describes a local example at its Chakhkal chlorination station. Smell alone does not establish the chlorine concentration or compliance with water quality requirements.
That concentration needs an appropriate measurement. Neither smell intensity nor a TDS reading can establish it. An absence of smell does not prove safety either.
If the smell is new or much stronger
Note when the change began, which taps are affected and whether the colour changed too. Give that information to your water supplier. Do not use a filter simply to conceal an unexplained change.
Veolia Djur tells its customers to stop using tap water and call 1-85 if its quality seems doubtful. Give your address and describe the problem, then follow the supplier’s instructions.
When the concern is the usual taste
Once any quality concern has been resolved, an appropriate carbon cartridge may help with an unwanted chlorine taste. NSF/ANSI 42 includes chlorine and taste/odour reduction requirements; check the actual claims for the selected model.
Reducing chlorine does not mean the cartridge removes all salts or disinfects against every microorganism. Treating all incoming water and treating only the drinking tap also involve different flow and maintenance requirements.
What to discuss with Filac
Tell Filac where your water comes from, describe its taste and explain what changed and when. Ask which stage addresses taste and odour and compare suitable home systems.
If the taste returns in filtered water, provide the last cartridge-change date. A service check should establish the cause; taste alone cannot identify the part that needs replacement.
