I refrained from reviewing for a few months because I wanted to make sure this worked. After 4 months, it works great. I called to have them troubleshoot the horrible smell I have in the water which smelled like rotten eggs and they recommended this. After a day, I could immediately tell the difference. The smell was quickly going away. I had still had a smell in the hot water line. They told me to Chlorine shock it and "bam" - it worked. It's so nice to have clean water again.
