Strange Water Smell

[cruise 0]

Hi

not sure where to post this thread....hope i'm doing it at the right place.

I wonder if you all face the same problem as me. I find that the water in my unit (I believe should affect other units sharing the same watertank in a HDB block) has different smell. One period it can smell like aluminim-kind, another period can smell like ammonia-kind. It's really difficult to describe the smell as it's very unusual. I've not find our singapore water to smell so strange before having lived all my life here. I remembered when I was younger the water sometimes tend to smell stronger chlorine-like...otherwise nothing else.

I called town council last time about the strange taste and smell, they claimed nothing unusual, will flush the water out. Said will get back to me but never did. After many weeks gone by then the water condition improved. so till today i still no idea what's wrong with the water and what they did to make it better. (so not transparent.....)

does anyone share the same issue? or suggest how or where can the water sample be tested?

thanks
