Query: Leaks

First, according to the documentation that came with it, this filter only removes about 50 percent of the chlorine in tap water, and it does not remove any chlorine byproducts at all. Thinking that any filter is better that no filter (usually applied to pitcher filters, etc.), I installed it anyway. It leaked. The O-ring that fits on either end of the little barrel filter had not seated properly. Water all over the place. Took it down. Took it apart. Put it back together. No leak for two months. Then the other day, turned on the shower, heard a pop, and it leaks again. Took it down, took it apart. Put it back together. Still leaks. It's going into the trash. Don't bother with this filter, if for no other reason than it's not very good at what it claims to do. There are more effective products out there. I have one in my other place.
