is the water okay to drink if it still isn't clear?
Depends what is in it - a little light sediment won't really hurt you.
It will not hurt you but running silty water such as dirty glacier water can really do a number on your filter. Pre-filter as much as you can for such instances. I have seen one person's gravity filter get compromised due to silt.
I work for Katadyn and have used first the Hiker & then the Hiker Pro since 1995 in all sorts of very dirty water. I've never had a trace of color come through, in even Colorado & San Juan River water.
Possibly an iron stained water might make it through, but otherwise, if it is less than a year old, return it for a warranty test, if more than a year old, replace the filter cartridge with a new one.
