Dual Tank — City Water
Our largest system. A separate carbon tank that cleans itself.
Two tanks instead of one — a dedicated softening tank and a dedicated carbon tank — bridged from a single ProValve. Splitting the media means each does its job properly, and the carbon tank backwashes itself clean.
Best for: Large homes, high usage, or heavily chlorinated city water
