RODI water smells nasty/bad.

[emanoids]

Anyone having the same scenario wherein the water produced by RODI stinks few months used? I suspect from resin?

The first few drops of the water stink ?

My bf uses a DIY unit. And I realized that the fishy smell came from the water. Does anyone faces that smell issue too? Not a pungent one but u can sniff out a fishy smell

Yes sometimes the resin smell foul especially after fully used (need resin change).

Probably due to it has absorb all those impurity from the tab water.

no after few months of usage. i think that is the indicator that it is expired already?

it is so smelly that it need to put strong disinfectant to sink or toilet just to remove the smell.

_{Sounds like you have anaerobic bacteria growing in your DIY RODI unit. The smell is probably hydrogen sulphide.}

_{I'm curious to know if you actually test the water using TDS meter and what is the reading.}

Smell like rotten eggs I guess...

I have been using RO/DI system for my drinking and water top for my tank for many years and have yet encounter any issue like your. Mind sharing What RO/DI system are you using? DIY?

I believed he does not use it often ... only use it when he changes water ...

If you use it daily should not have the smell

I do experience the same smell. It's just that I didn't use often which probably causes the smell. I just let it run for a good few sec. then test the TDS...

To me it does not effect the TDS reading, It just the gas being release from the water after long storage in the my DI system.

thanks for the feedback guys! i am using rodi from madpetz. It does not affect TDS just that it is so smelly - but yes i think you are all right coz i only use it when all my rodi water reservoir is empty already and when start to use it again that is when it smells. I should let the water flow always on it.
