A water treatment system is provided having an encapsulate manifold with a reverse osmosis cartridge and one or more filter cartridges, and an annular collar to adapt and connect the manifold to the cartridges. The filter cartridge includes a detent for being received within a slot in the manifold head for secure locking engagement. The water treatment system is also provided in a modular arrangement wherein manifold heads are physically and fluidly coupled together via a clip which interfaces with the modular manifold heads. The water treatment system also allows for a retrofit application to include a permeate pump. The cartridges are also designed to provide a minimum annular inlet gap to minimize spillage during changing of the cartridges.

The present invention provides a method and system of anticipating salt depletion in a brine tank of a water softener system, the system including a controller having a user interface and display, the method comprising the steps of tracking salt usage; determining the amount of salt remaining in the brine tank; calculating the number of days before salt is required in the brine tank based on salt usage and the amount of salt remaining in the brine tank; and providing an indication of the number of days to empty, whereby a user is able to anticipate the need to replenish the salt supply and plan accordingly to assure continuous satisfactory operation of the water softener system.
