ABSTRACT:
A filter assembly is provided for a manifolded water filtration system and includes a filter element, a brine seal located at the top of the filter element and engaging a boss depending from the system manifold. The brine seal isolates a rinse water discharge port, communicating with a an outlet of the filter element, from an untreated water inlet port formed in the boss so as to ensure that the water to be treated passes through the filter membrane as opposed to directly out of the rinse water discharge port. This configuration eliminates the need for an exterior feed line, thus simplifying the system and preventing vibration during system start-up. The brine seal also structurally reenforces the filter element, facilitates assembly of the filter, increases the capacity of the assembly, and reduces the chances of failure and leakage.
