I purchased the Herpstat 4 for a big project I was working. Unfortunately I ran out of space and had to cancel the project. I never used the herpstat 4 and it is just sitting in the box collecting dust. I am looking to sell it at this point so i thought I would try here first! Any questions...
Hmmm this one just ties to the cold water line... I YouTubed the installation it was pretty easy. Just need some room under sink for the filters and the reservoir.
