I installed a KDF GAC(4:6 by weight) filter (counter-top) to reduce possible heavy metals and chlorine in the water. (our water tastes generally good, except slightly chlorine)
However, after running the water through the filter we get a very strong rotten egg smell/taste. (assuming H2S)
Note: The water states/smells fine before filtration (or on any other tap in the house) except for slightly chlorine.
After some research; The filter should remove H2S not introduce it.
I can't find any reason other than it might be due to bacteria growth or the filter is saturated. But since this is a new filter I got yesterday... I'm completely stumped.
Why would a new KDF/GAC filter cause a rotten egg smell/taste?
PS. I've also let it run for 5 minutes at +-5.56L/min (+- 28L) without any improvement.
